Abstract

This invention is based on surprising results that certain concentrations of certain sugars stabilize cyclopropene and at least one sugar. Also provided are methods of using such compositions for inhibiting an ethylene response in a plant.

Claims (24)

1. A stable liquid composition comprising an aqueous solution of 1-methylcyclopropene (1-MCP) and at least one sugar,

wherein the 1-MCP is encapsulated,

wherein the at least one sugar comprises sucrose,

wherein the aqueous solution is at least 60% saturated or supersaturated with the sucrose.

2. The stable liquid composition of claim 1 , wherein the 1-MCP is part of a molecular complex.

3. The stable liquid composition of claim 2 , wherein the molecular complex is an inclusion complex.

4. The stable liquid composition of claim 2 , wherein the molecular complex comprises the 1-MCP and a molecular encapsulating agent.

5. The stable liquid composition of claim 4 , wherein the molecular encapsulating agent forms a cavity and the 1-MCP or a portion of the 1-MCP is located within the cavity.

6. The stable liquid composition of claim 4 , wherein the molecular encapsulating agent is selected from the group consisting of substituted cyclodextrins, unsubstituted cyclodextrins, crown ethers, zeolites, and combinations thereof.

7. The stable liquid composition of claim 4 , wherein the molecular encapsulating agent comprises a cyclodextrin.

8. The stable liquid composition of claim 7 , wherein the cyclodextrin is selected from the group consisting of alpha-cyclodextrin, beta-cyclodextrin, gamma-cyclodextrin, and combinations thereof.

9. The stable liquid composition of claim 7 , wherein the cyclodextrin is a modified cyclodextrin or a cyclodextrin polymer.

10. The stable liquid composition of claim 7 , wherein the cyclodextrin is a substituted cyclodextrin.

11. The stable liquid composition of claim 7 , wherein the cyclodextrin is beta-cyclodextrin.

12. The stable liquid composition of claim 4 , wherein the molecular encapsulating agent comprises an organic molecular encapsulating agent.

13. The stable liquid composition of claim 4 , wherein the molecular encapsulating agent comprises an inorganic molecular encapsulating agent.

14. The stable liquid composition of claim 1 , wherein the stable liquid composition is stable over a period of at least 10 days.

15. The stable liquid composition of claim 1 , wherein the stable liquid composition is stable over a period of at least 30 days.

16. The stable liquid composition of claim 1 , wherein the stable liquid composition is stable over a period of at least one year.

17. The stable liquid composition of claim 1 , wherein the stable liquid composition comprises more than one sugar.

18. The stable liquid composition of claim 17 , wherein the more than one sugar is selected from the group consisting of monosaccharides, disaccharides, trisaccharides, oligosaccharides, polysaccharides, and combinations thereof.

19. The stable liquid composition of claim 18 , wherein the more than one sugar comprises a polysaccharide.

20. The stable liquid composition of claim 17 , wherein the more than one sugar comprises a sugar derivative.

21. The stable liquid composition of claim 1 , wherein the aqueous solution is 90-100% saturated or supersaturated with the sucrose.
