Claims
- 1. A plant growth promoting compound having the structure: whereA is oxygen or a direct bond, B is —CH2CH2—, OP is hydroxyl or protected hydroxyl, R1 is hydrogen or methyl, and R2 is hydrogen or methyl.
- 2. The compound of claim 1, where the configuration at C24 is either substantially R (α) or substantially S (β).
- 3. The compound of claim 2, where the configuration at C24 is substantially S (β).
- 4. The compound of claim 1, where R1 and R2 are hydrogen.
- 5. The compound of claim 3, where R1 and R2 are hydrogen.
- 6. The compound of claim 5, where A is oxygen.
- 7. The compound of claim 6, where and OP is hydroxyl.
- 8. A plant growth promoting composition comprising a compound having the structure of claim 1, where OP is hydroxyl, in a suitable delivery vehicle.
- 9. The composition of claim 8, wherein in said compound, the configuration at C24 is substantially S, R1 and R2 are hydrogen, and A is oxygen.
- 10. The composition of claim 8, further comprising a plant growth factor selected from the group consisting of an auxin, a gibberellin, and a cytokinin.
- 11. The composition of claim 10, wherein said plant growth factor is an auxin.
- 12. The composition of claim 11, wherein said plant growth factor is 3-indole acetic acid (IAA) or α-naphthalene acetic acid (NAA).
- 13. A method of promoting plant growth, comprising applying to the plant, in a suitable delivery vehicle, an effective amount of a compound having the structure of claim 1, where OP is hydroxyl.
- 14. The method of claim 13, wherein in said compound, the configuration at C24 is substantially S, R1 and R2 are hydrogen, and A is oxygen.
- 15. The method of claim 13, where said plant is a cereal crop.
- 16. The method of claim 13, further comprising applying to said plant a plant growth factor selected from the group consisting of an auxin, a gibberellin, and a cytokinin.
- 17. The method of claim 16, wherein said plant growth factor is an auxin.
- 18. The method of claim 17, wherein said plant growth factor is 3-indole acetic acid (IAA) or α-naphthalene acetic acid (NAA).
