Abstract

The present disclosure provides the use of 4-(Phenylethynyl) benzoic acid in preparing a plant growth regulator. 4-(Phenylethynyl) benzoic acid has a formula as C15H10O2, a molecular weight of 222.2390. The optimum concentration of 4-(Phenylethynyl) benzoic acid in the plant growth regulator is in a range of 10 μM to 200 μM. The plant growth regulator further contains a pesticidally acceptable carrier. The present disclosure further provides the use of 4-(Phenylethynyl) benzoic acid in regulating plant growth. In the use of 4-(Phenylethynyl) benzoic acid in preparing a plant growth regulator of the present disclosure, 4-(Phenylethynyl) benzoic acid has the ABA-like effects, and is more stable, easily available, cheaper, and environmentally friendly. Therefore, the present disclosure is suitable for large-scale popularization.

First claim

The invention claimed is:

1. A method of inhibiting seed germination, the method comprising:
providing a solution comprising 4-(Phenylethynyl) benzoic acid; and
inhibiting the seed germination using the solution.

2. The method of claim 1 , wherein the 4-(Phenylethynyl) benzoic acid has a formula as C 15 H 10 O 2 , a molecular weight of 222.2390, and a structure as follows:

3. The method of claim 2 , wherein a concentration of 4-(Phenylethynyl) benzoic acid in the solution is in a range of 10 μM to 200 μM.

4. The method of claim 3 , wherein the solution further comprises a pesticidally acceptable carrier comprising water, dimethyl sulphoxide (DMSO), at least one buffer, Hoagland nutrient solution, at least one surfactant, or a combination thereof.

5. A method of blocking radicle elongation, the method comprising:
providing a solution comprising 4-(Phenylethynyl) benzoic acid; and
blocking the radicle elongation using the solution.

6. The method of claim 5 , wherein the 4-(Phenylethynyl) benzoic acid has a formula as C 15 H 10 O 2 , a molecular weight of 222.2390, and a structure as follows:

7. The method of claim 6 , wherein a concentration of the 4-(Phenylethynyl) benzoic acid in the solution is in a range of 10 μM to 200 μM.

8. The method of claim 7 , wherein the solution further comprises a pesticidally acceptable carrier comprising water, dimethyl sulphoxide (DMSO), at least one buffer, Hoagland nutrient solution, at least one surfactant, or a combination thereof.

9. A method of promoting stomata closure, the method comprising:
providing a solution comprising 4-(Phenylethynyl) benzoic acid; and
promoting the stomata closure using the solution.

10. The method of claim 9 , wherein the 4-(Phenylethynyl) benzoic acid has a formula as C 15 H 10 O 2 , a molecular weight of 222.2390, and a structure as follows:

11. The method of claim 10 , wherein a concentration of 4-(Phenylethynyl) benzoic acid in the solution is in a range of 10 μM to 200 μM.

12. The method of claim 11 , wherein the solution further comprises a pesticidally acceptable carrier comprising water, dimethyl sulphoxide (DMSO), at least one buffer, Hoagland nutrient solution, at least one surfactant, or a combination thereof.
