Abstract

The present invention is directed to methods of improving plant growth by applying an effective amount of (S)-abscisic acid and glycine betaine to the plant. The present invention is further directed to methods of improving stress tolerance in a plant by applying an effective amount of (S)-abscisic acid and glycine betaine to the plant.

First claim

The invention claimed is:

1. A method of improving plant growth comprising applying an effective amount of (S)-abscisic acid ((S)-ABA) and glycine betaine (GB) to the plant, wherein the weight ratio of (S)-ABA:GB is from about 1:1 to about 1:33.

2. The method of claim 1 , wherein the plant is subject to an abiotic stress.

3. The method of claim 2 , wherein the abiotic stress is cold stress.

4. The method of claim 2 , wherein the abiotic stress occurs prior to the application of (S)-ABA and GB.

5. The method of claim 2 , wherein the abiotic stress occurs after the application of (S)-ABA and GB.

6. The method of claim 1 , wherein the plant is a monocotyledonous plant.

7. The method of claim 6 , wherein the monocotyledonous plant is corn.

8. The method of claim 1 , wherein the plant is a dicotyledonous plant.

9. The method of claim 8 , wherein the dicotyledonous plant is selected from the group consisting of cucumber and basil.

10. The method of claim 1 , wherein (S)-ABA is applied at a rate of about 1 to about 100 grams per hectare and GB is applied at a rate of about 1 to about 1,000 grams per hectare.

11. A method of improving stress tolerance in a plant comprising applying an effective amount of (S)-abscisic acid ((S)-ABA) and glycine betaine (GB) to the plant, wherein the weight ratio of (S)-ABA:GB is from about 1:1 to about 1:33.

12. The method of claim 11 , wherein the stress is an abiotic stress.

13. The method of claim 12 , wherein the abiotic stress is cold stress.

14. The method of claim 11 , wherein the stress occurs prior to the application of (S)-ABA and GB.

15. The method of claim 11 , wherein the stress occurs after the application of (S)-ABA and GB.

16. The method of claim 11 , wherein the plant is a monocotyledonous plant.

17. The method of claim 16 , wherein the monocotyledonous plant is corn.

18. The method of claim 11 , wherein the plant is a dicotyledonous plant.

19. The method of claim 18 , wherein the dicotyledonous plant is selected from the group consisting of cucumber and basil.

20. A composition comprising (S)-abscisic acid ((S)-ABA) and glycine betaine (GB), wherein the weight ratio of (S)-ABA:GB is from about 1:1 to about 1:33.
