The present invention relates to a rooting system and the use of said rooting system. The invention further relates to a method of rooting of vegetative cuttings. The invention also relates to an assembly comprising said rooting system a plant material.
Plant material is commonly reproduced via vegetative cuttings. Such vegetative cuttings are often a cutting of about 5 cm in length of a portion of a mother plant, which may include one or more leaves. The unrooted cutting is typically inserted in a growth media such as a growth cell or “plug” containing growth media and nutrients until roots are formed. The rooted cutting in the growth cell, often termed a liner, is then distributed to a plant grower. The liner is then transplanted into a container and grown until the plant achieves a growth stage suitable for distribution in the marketplace. Such growth cells or plugs often contain soil or a soil replacement. The disadvantage of soil or soil replacement is that these are often prohibited from being imported into countries. Soilless media are desirable for their ability to be imported from one country to another. Further downsides are that soil and soil replacements are heavy, especially if kept wet, and take up a relative large amount of space which are both disadvantageous for transport.
It is an object of the present invention to provide for an improved growing medium.
It is further an object of the present invention to provide for a growth medium overcoming the disadvantages of the growth media according to the prior art.
The present inventor has surprisingly found that the above objects are met by a soilless rooting system comprising: an elongated holder having a first portion and a second portion extending the length of the holder, said first and second portions comprising a material that permits roots from a vegetative cutting to grow therethrough.
The present invention is directed to a soilless rooting system that includes an elongated holder having a first portion and a second portion that extends to the length of the holder. The first and second portions include a material that permits roots from a vegetative cutting to grow therethrough. The present invention also includes a method of rooting vegetative cuttings by providing the rooting system and placing the vegetative cutting adjacent one of the first and second portions. The first and second portions are adhered together, thereby sandwiching the vegetative cutting therebetween.
The present invention includes a rooting system for germinating seeds or for producing a callus and/or roots of a vegetative cutting, and may be used to package, store, and transport the same. The present invention further relates to the use of said rooting system in growing plant material. The present invention is described in relation to the production of rooted cuttings from unrooted cuttings, but this is not meant to be limiting. For example, the present invention may also be used with tissue culture, bare root cuttings, or seeds. Thus, reference to rooting is also applicable to germinating. In addition, the present invention is not limited to use with any particular species of plants or crops, any ornamental and/or agricultural species may be used.

The present invention is illustrated in more detail in the following description and with reference to the drawings, in which:
As shown in
In one embodiment, the holder 2 is folded longitudinally along the web 8 between first and second portions 4, 6 as shown in
As the elongated holder 2 is folded, an unrooted cutting UC is inserted therebetween, as shown in
For some unrooted cuttings, it may be beneficial to support the holder 2 such that any leaves of the unrooted cuttings UC are free, with the roots able to grow in an opposite direction. For example, as shown in
The process of sticking the unrooted cuttings UC into the rooting system may be automated using a dispensing system 20, as shown schematically in
The embodiment disclosed above considers the use of a one-piece elongated holder 2 having a first portion 4 and a second portion 6, and a web or liner 8 that supports the first and second portions 4, 6. However, the first and second portions may be separate components that are adhered together after the unrooted cuttings are inserted therebetween. In addition, the first and second portions may be held together by any mechanism, such as organic or inorganic glue, adhesive, heat fusion, staples, zippers, zip locks, or the like. Alternatively, one portion may be positioned on top of the other portion with the plant material placed in between for rooting. In this embodiment, an unrooted cutting may be placed onto one portion, allowed to root, and the second portion is laid thereover after rooting occurs. Alternatively, the elongated holder 2 may be a unitary structure with openings provided therein for insertion of the unrooted cuttings UC. Upon rooting, the roots grow out through both portions, such that the rooted cutting binds the two portions together.
The elongated holder 2 may be produced from inorganic or synthetic materials so that the rooted cuttings RC may be transported between countries that do not permit importation of organic rooting material, such as soil and bark. For example, the elongated holder 2 may be a synthetic material, such as polyester, nylon, or polyethylene terephthalate (e.g., fleece), and may be woven or non-woven. In one embodiment, the elongated holder 2 may be biodegradable, such as paper or other cellulosic material. In addition, the elongated holder 2 may be provided of any length, width, thickness, color, texture, scent, or shape that allows the plant material to develop roots and sustain the roots until transplanted into a growth media or soil. The elongated holder 2 should have a porosity that allows the unrooted cutting UC to grow roots R therethrough and be sufficiently permeable to water so that the cuttings UC or RC may be watered. In one embodiment, the cuttings UC or RC are treated with water containing optionally 50 ppm nitrogen, such as in the form of calcium nitrate. The soilless rooting system containing cuttings UC or RC may also be misted to maintain moisture in the rooting system.
After rooting has been accomplished, the rooted cuttings are suitable for transplanting. The rooted cuttings may be inserted into a transport device, such as an elongated plastic sleeve (not shown), which may be perforated to allow air flow. Sleeves containing holders with the rooted cuttings can then be packed into containers, such as cardboard boxes, with ice packs.
In an embodiment the elongated holder 2 is provided with information, preferably in the form of a bar code, quick response (QR) code or an information carrier such as an Radio-frequency identification (RFID) tag.
