The present invention, in some embodiments thereof, relates to a plant, e.g., a tree, with differential altitude and distributed root system. The present invention, in some embodiments thereof, further relates to an elevating facade, e.g., a wall, which is covered, at least in part, by a plant with a distributed root system, thereby generating a living facade, e.g., a living wall, carrying the plant with a distributed root system thereon. The present invention, in some embodiments thereof, further relates to methods of producing the plant and the living facade.
Under typical growth conditions, a plant of any given species develops root and foliage systems of a characteristic evolutionary predetermined size before flowering and/or fruiting. A plant is considered a mature plant when its root and foliage systems have reached the characteristic evolutionary predetermined size.
From an evolutionary perspective, in order to increase its chances of survival, under stress conditions, a plant may flower and produce fruits even before its root and/or foliage systems reached their characteristic evolutionary predetermined size.
For a similar reason a mature plant may skip flowering and/or fruiting in a certain year due to biotic or abiotic stress conditions, so as to allocate the limited resources available that year to survival as opposed to reproduction and delay reproduction to years when the stress is relieved.
Living walls, vertical vegetation, green facades, wall gardens, etc., are all phrases describing non horizontal structural elements formed with surfaces (typically vertical surfaces) that physically support the growth of vegetation thereon, or adjacent thereto.
Often times, the following terminology is used in the art to describe elevating vegetation:
1. The phrase “green facade” is often used in the art to describe vines and climbers that grow from the ground or from large containers at various locations on the exterior of structures. The climbers are supported either by the wall itself (the traditional green facade) or by a supporting trellis/mesh. An illustration of a green facade is shown in
2. The phrase “living wall” is often used in the art to describe plants that grow from a vertical layer of a growing medium. Within the living wall category, some of the architectures are based on plants growing hydroponically, typically planted in layers of synthetic felt, therefore called “vegetated mat”. An illustration of a living wall in the form of a vegetated mat is shown in
3. Other living walls are based on panels or pockets filled with a more traditional growing medium (e.g., potting mix). These architectures are oftentimes to called “panel system”, “pocket system” or modular living walls. An illustration of a modular living wall is shown in
It is to be understood that the nomenclature characterizing the art to which this invention relates is constantly developing and the phrases used above should not be deemed limited by the above descriptions.
Under the preferred embodiments section that follows, the reader shall find definitions for the terminology and lexicography which is exploited throughout the current document in order to describe the present invention.
To date, the practice of growing plants on walls is limited to plants with relatively small root systems, because root space is seriously limited by the space made available by living wall architectures.
As a result, trees are rarely grown over walls, let alone flowering and fruiting trees. When trees are grown on walls, in order to reach maturity they require massive containers formed in, or attached to, the wall in order to allow the tree to develop a root system of sufficient functional size to support a mature foliage system, flowering and fruiting. Failing to provide such conditions may result in poorly and immature appearing trees.
The present invention provides a novel insight to the elevated vegetation art, which allows to overcome the limitations imposed by limited root space.

Unless otherwise defined, all technical and/or scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the invention pertains. Although methods and materials similar or equivalent to those described herein can be used in the practice or testing of embodiments of the invention, exemplary methods and/or materials are described below. In case of conflict, the patent specification, including definitions, will control. In addition, the materials, methods, and examples are illustrative only and are not intended to be necessarily limiting.
Some embodiments of the invention are herein described, by way of example only, with reference to the accompanying drawings. With specific reference now to the drawings in detail, it is stressed that the particulars shown are by way of example and for purposes of illustrative discussion of embodiments of the invention. In this regard, the description taken with the drawings makes apparent to those skilled in the art how embodiments of the invention may be practiced.
In the drawings:
The present invention, in some embodiments thereof, relates to a plant, e.g., a tree, with differential altitude and distributed root system, which can be used in elevated vegetation applications. The present invention, in some embodiments thereof, further relates to an elevating facade, e.g., a wall, which is covered, at least in part, by a plant with a distributed root system, e.g., differential altitude and distributed root system, thereby generating a living facade, e.g., a living wall, carrying thereon the plant with the distributed root system. The present invention, in some embodiments thereof, further relates to methods of producing the plant and the living facade.
Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not necessarily limited in its application to the details of construction and the arrangement of the components and/or methods set forth in the following description and/or illustrated in the drawings and/or the Examples. The invention is capable of other embodiments or of being practiced or carried out in various ways.
The following terms and phrases are used herein to describe the present invention.
The term “facade” is used herein to describe a face of a natural (e.g., hill of cliff side) or man-made (e.g., an external or an internal wall of a building) structure.
The phrase “elevating facade” is used herein to describe a facade which is not horizontal. Typically an elevating facade forms an angle of between 30-90 or 40-90 or 50-90 or 60-90 or 70-90 or 80-90 or about 90 or 90 degrees with the horizon. In the latter case, the facade is a vertical facade, namely, orthogonal to the horizon.
The term “about” is used herein to indicate +/−5% of a specified value.
The phrase “elevating vegetation” is used herein to describe vegetation grown over the surface of an elevating facade. When the elevating facade is a vertical facade, the elevating vegetation is vertical vegetation.
The term “plant” is used herein to describe an organism of the kingdom plantae.
The phrase “single plant” is used herein to describe a single organism. By “single organism” it is meant that any cell or natural structure of the organism is connected directly or indirectly (via other cells and natural structures) to all other cells or natural structures of the organism. A single plant or a single organism according to the invention may have more than a single genetic or species origin, as it may be the case, e.g., in grafted or artificially inosculated trees. All parts of a single plant according to the invention share commonly functional vasculature (xylem and phloem). In some embodiments of the invention the plant is a tree, e.g., a fruit tree.
The phrase “root system” is used herein to describe the entire underground root structure of a single plant.
The phrase “foliage system” is used herein to describe the entire aboveground foliage structure of a single plant.
The phrase “flowering and/or fruiting supporting root system” is used herein to describe a root system which is sufficiently sized to support flowering and/or fruiting, respectively, of a plant under typical growth conditions.
The phrase “flowering and/or fruiting supporting foliage system” is used herein to describe a foliage system which is sufficiently sized to support flowering and/or fruiting, respectively, of a plant under typical growth conditions.
The phrase “typical growth conditions” is used herein to describe growth conditions which are sufficiently non-stressful so as not to induce plant “pre-death” flowering and/or fruiting.
The phrase “distributed root system” is used herein to describe a root system with is partitioned into at least two or more spatially separated root aggregates or clusters. A root cluster according to the invention is typically smaller in size as compared to a mature root system of the same plant. Under typical growth conditions, a root cluster according to the invention is too small to support flowering and/or fruiting of the plant. The size of a root cluster according to the invention is limited by the confinement in which it is contained. It will be appreciated that the present invention is useful, for example, in cases where a natural size of a root system of a plant requires more soil volume than what is offered by a single confinement.
The term “confinement” is used herein to describe a restricted space available for root growth. The confinement may be a container formed in or on an elevating facade.
The phrase “differential altitude and distributed root system” is used herein to describe a root system with is partitioned into at least two or more spatially separated root aggregates or clusters, wherein at least two of said aggregates or clusters are at a different altitude. The differential altitude and distributed root system is typically allowed to grow to a combined size which is equal to or larger than a mature root system of the same plant when grown on land.
The phrase “plant structure” is used herein to describe a portion of the plant anatomy which is characterized by morphological, functional and developmental parameters. Plant structures, as used herein, include, but are not limited to “root”, “stem” and “shoot”. Roots, stems and shoots are all vascular structures, with stems and shoots, but not roots being node-bearing structures.
The term “root” is used herein to describe the non-leaf, non-node-bearing part of a plant.
The term “stem” is used herein to describe the stalk of a plant or the main trunk of a tree. A stem may include but is not limited to: stalk, stock, shoot, trunk and axis.
The term “shoot” is used herein to describe new plant growth that can grow from seed or axillary buds. A shoot may include but is not limited to: branch, bough, growth, offshoot, sprig and scion. Both stems and shoots are node-bearing plant structures.
Typically the plant root is positively gravitropic, in contact with the growth medium and located below the soil surface, while the stem and/or shoot is typically negatively gravitropic, above the soil surface and exposed to the air. However, under certain circumstances, portions of the root cluster may develop above the soil surface (for example, aerial roots), and portions of the shoot or stem may grow horizontally at the soil surface or just below it (for example, stolons or runners), or not only horizontally but at a different orientation (vertically or obliquely) to the soil surface (for example, “rhizomes”).
The phrase “a portion of a plant structure” is used herein to describe a subdivision of the plant structure. Roots, stems and shoots of most plants and trees comprise complex and diverse outgrowths for example, a branch of a limb or bough, or a sprig of a shoot, primary and adventitious roots, or other subdivisions of the root cluster and specialized stem growths such as bulbs. Thus, the methods of the present invention can be performed using an entire plant structure, such as a shoot or a stem, or any portion or subdivision (natural or artificially formed) of the structure (for example, a few individual roots of the root cluster and the like), with the proviso that the structure have the capability of forming a vascular connection with the other, spatially separated root aggregates or clusters of the distributed root cluster.
According to the invention, the size of a root system is limited by the size and number of the confinements in which it grows, and since the number of confinements is readily increasable, root systems of any size can be grown. Thereby, allowing the growth of large trees.
The phrase “distributed foliage system” is used herein to describe a foliage system with is partitioned into at least two or more spatially separated foliage aggregates or clusters.
The phrase “differential altitude and distributed foliage system” is used herein to describe a foliage system with is partitioned into at least two or more spatially separated foliage aggregates or clusters, wherein at least two of said aggregates or clusters are at a different altitude.
The phrase “plant cluster” is used herein to describe an aggregate of plant organs including at least a clustered root system and optionally also a stem and a clustered foliage system or a non-segregated foliage system.
The phrase “living facade” is used herein to describe a facade at least partially covered by a plant or plants.
The phrase “living wall” is used herein to describe a wall at least partially covered by plant or plants.
Under typical growth conditions, a plant, e.g., a tree, under typical growth conditions, must reach maturity prior to flowering and fruiting. Plant maturity in this context greatly depends on a suitable size of the root system of the plant. Plant maturity in this context may also greatly depend on a suitable size of the foliage system of the plant.
In vertical vegetation, confinement size severely limits the size of the root system that can develop therein, thereby limiting the size of the foliage, which, under typical growth conditions is correlated to the size of the root system.
The inventor of the present invention realized that a plant having a distributed root system may be used to allow a single plant to develop a plurality of distributed root clusters that collectively form a root system of a size sufficient to support flowering and/or fruiting of the plant under typical growth conditions. The plurality of root clusters may be contained in a plurality of confinements formed in or on an elevating facade, thereby rendering moot the confinement size limitation that characterizes the prior art and which thus far practically prevented vertical vegetation of larger plants such as trees, e.g., fruit trees.
The inventor of the present invention has developed numerous methods of generating a plant having a distributed root system, e.g., a differential altitude and distributed root system for use in context of the invention. These methods are described below, followed by a description of the plants generated there from and the facades that make use thereof.
Thus, as shown in
In air layering, a target region of a branch is wounded and surrounded in a moisture-retaining wrapper, such as, but not limited to, sphagnum moss, which is further surrounded in a moisture bather, such as, but not limited to, a polyethylene film. When sufficient roots have grown from the wound, the wrapper is removed and the novel root cluster is planted in soil, or alternatively, soil or soil replacement (e.g., potting mix) is added to support root growth.
In soil layering, a target region of a branch is wounded and placed in soil or soil replacement to induce root growth in situ.
In either case, a rooting hormone, such as, but not limited to, abscisic acid (ABA), 1-Naphthaleneacetic acid (NAA) and/or 1-Naphthaleneacetamide, may be applied to encourage the wounded region to grow roots.
As shown in
Functional fusion of branches 16a and 16b may be carried out by a process known as inosculation, whereby branches merge as a result of their cambiums grafting together slowly as they grow adjacent to each other.
As shown in
As shown in
Various plant structures can be used for generating a plant having a differential altitude and distributed root system. Thus, according to some embodiments of the present invention there is provided still another method of generating a plant having a differential altitude and distributed root system. According to this aspect of the invention the method comprises first obtaining a plant having a root cluster in a first confinement, and inducing a structure of the plant to generate an additional root cluster in a second confinement. According to this aspect of the invention, the first confinement and second confinement are located at different altitudes. According to another aspect of the present invention, the method may be repeated with the plant grown in the first or the second confinement, or both, to provide a method of generating a plant having a plurality of different altitudes and distributed root systems.
According to some embodiments of the present invention there is provided still another method of generating a plant having a differential altitude and distributed root system. According to this aspect of the invention the method comprises obtaining a first plant having a root cluster in a first confinement and a second plant having a second root cluster in a second confinement and inducing a portion of a structure of the first plant to functionally fuse with a portion of a structure of the second plant, where the first confinement and said second confinement are at different altitudes, generating a plant having a different altitudes and distributed root systems. According to another aspect of the present invention, the method may be repeated with the plant grown in the first or the second confinement, or both, to provide a method of generating a plant having a plurality of different altitudes and distributed root systems. According to this aspect of the invention, the plant structure is selected from the group consisting of a root, a stem and a shoot. In some embodiments, the structure of the first plant is a root and the structure of the second plant is a root, and the roots are induced to functionally fuse. In other embodiments, the structure of the first plant is a root and the structure of the second plant is a shoot, and the root and shoot are induced to functionally fuse. In yet other embodiments, the structure of the first plant is a root and the structure of the second plant is a stem, and the root and stem are induced to functionally fuse.
In some embodiments, the structure of the first plant is a shoot and the structure of the second plant is a shoot, and the shoots are induced to functionally fuse. In other embodiments, the structure of the first plant is a shoot and the structure of the second plant is a root, and the shoot and root are induced to functionally fuse. In yet other embodiments, the structure of the first plant is a shoot and the structure of the second plant is a stem, and the shoot and stem are induced to functionally fuse.
In other embodiments, the structure of the first plant is a stem and the structure of the second plant is a stem, and the stems are induced to functionally fuse. In other embodiments, the structure of the first plant is a stem and the structure of the second plant is a root, and the stem and root are induced to functionally fuse. In yet other embodiments, the structure of the first plant is a stem and the structure of the second plant is a shoot, and the stem and shoot are induced to functionally fuse.
It will be appreciated that, in some embodiments of the present invention, multiple or a plurality of plant structures can be induced to functionally fuse. For example, in some embodiments, generating a plant having a differential altitude and distributed root system comprises obtaining a first plant having a root cluster in a first confinement and a second plant having a second root cluster in a second confinement and inducing a portion of at least two structures of the first plant to functionally fuse with a portion of at least two structures of the second plant, where the first confinement and said second confinement are at different altitudes, generating a plant having a different altitudes and distributed root systems, comprising a plurality of plant structures having vascular connections between the parts of the plant in the first and second confinements. The at least two structures of the first plant can be identical structures (at least two stems, at least two shoots, etc), or different structures (at least one stem and at least one shoot, at least one root and at least one stem, etc), or combinations thereof. The at least two structures of the second plant can also be identical structures (at least two stems, at least two shoots, etc), or different structures (at least one stem and at least one shoot, at least one root and at least one stem, etc), or combinations thereof.
Thus, for example, in some embodiments a plant having different altitudes and distributed root systems, comprising a plurality of plant structures having vascular connections between the parts of the plant in the first and second confinement can be generated by inducing fusion between a shoot of the first plant and a stem of the second plant, AND additionally inducing fusion between a root of the first plant and a shoot of the second plant, producing a plant having different altitudes and distributed root systems, comprising a plurality of plant structures having vascular connections between the parts of the first and second confinements. According to some embodiments, the at least two structures of the first and second plants can be two, three, four, five or more structures, and the plurality of plant structures having vascular connections between the parts of the plant in the first and second confinements can include two, three four, five or more structures having vascular connections between the parts of the plant in the first and second confinement. Such plant having a plurality of plant structures having vascular connections between the parts of the plant in the first and second confinements may benefit from additional vascular connection between the parts of the plant at different altitudes, enabling, inter alia, effective bidirectional movement of nutrients and fluids between the parts of the plants in the first and second confinements.
It will be appreciated that, as in the other methods described herein, such a method for generating a plant having a plurality of plant structures having vascular connections between the parts of the plant in confinements of different altitudes can optionally be performed using not only a first and second but also a third and fourth or more confinements concurrently.
According to another aspect of the present invention, the portion of the structure that is induced to generate a root cluster, or functionally fuse to a portion of a structure of the second plant is in vascular connection with the structure.
It will be appreciated that in some embodiments of the present invention, generating a plant having different altitudes and distributed root systems or a plurality of plant structures having vascular connections between the parts of the plant in confinements of different altitudes can be achieved by using more than one structure, or more than one portion of a structure according to the methods of the present invention. Thus, in some embodiments of the invention, two, three, four or more shoot, stem or root structures of the plant in the first confinement may be induced to generate a second root cluster in the second confinement. Further, in some embodiments of the invention, two, three, four or more shoot, stem or root structures of the plant in the first confinement may be induced to fuse in vascular connection with the structure, structures, or portions thereof of the second plant in the second confinement.

Some plants may require continuous root growth in order to maintain viability. In such cases, extra confinements may be constructed to allow future use and root growth.
When a root cluster of a plant of the invention fills up the confinement in which it grows, the root cluster may die. In this case, the growing medium in this confinement may be renewed and a new root cluster and foliage cluster grown therein using any one of the methods of the present invention.
In addition, in a case whereby a root cluster of a plant dies and as a result the plant parts into two independent plants, the two independent plants may be rejoined into a single plant using the methods of the present invention, e.g., the method described in
The present invention allows for the first time the cultivation of large trees such as fruit trees on living facades. When grown as described herein, a tree with a differential altitude distributed root system and optionally a differential altitude distributed foliage system have its weight distributed over the area of the wall and will be fastened in many locations to the vertical surface, thus conferring greater structural stability and greater resilience to wind and weight induced load stresses.
Fruit trees are particularly suited for cultivation on living facades where agricultural produce is desired, since, unlike many other crop plants, many species of fruit trees are capable of surviving through periods of cold temperatures without special attention and sheltering (overwintering).

As used herein, the singular form “a”, “an” and “the” include plural references unless the context clearly dictates otherwise.
As used herein the term “method” refers to manners, means, techniques and procedures for accomplishing a given task including, but not limited to, those manners, means, techniques and procedures either known to, or readily developed from known manners, means, techniques and procedures by practitioners of the horticulture art.
It is appreciated that certain features of the invention, which are, for clarity, described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the invention, which are, for brevity, described in the context of a single embodiment, may also be provided separately or in any suitable subcombination or as suitable in any other described embodiment of the invention.
