Abstract
Methods of applying cyclopropene derivatives and compositions thereof to block ethylene receptors in plants are disclosed. One such method comprises applying to the plant an effective ethylene response-inhibiting amount of cyclopropene derivatives or compositions thereof. Also disclosed are methods of inhibiting abscission in plants, methods of prolonging the life of cut flowers, methods of inhibiting ripening of picked fruits, and methods of inhibiting ripening of picked vegetables.

A method of inhibiting an ethylene response in a plant, comprising applying to the plant an effective ethylene response-inhibiting amount of a compound of Formula I:
- 15
- wherein:
- n is a number from 1 to 4;
- and
- each R is independently a saturated or unsaturated, linear or branched-chain, unsubstituted or substituted, C5-C20 alkyl, alkenyl, or alkynyl, wherein at least one R is a saturated or unsaturated, linear or branched-chain, unsubstituted or substituted C5 alkyl, alkenyl, or alkynyl.
A method of prolonging the life of a cut flower, comprising applying to the cut flower an effective life-prolonging amount of a compound of Formula I:
- 16
- wherein:
- n is a number from 1 to 4;
- and
- each R is independently a saturated or unsaturated, linear or branched-chain, unsubstituted or substituted, C5-C20 alkyl, alkenyl, or alkynyl, wherein at least one R is a saturated or unsaturated, linear or branched-chain, unsubstituted or substituted C5 alkyl, alkenyl, or alkynyl.
A method of inhibiting an ethylene response in a plant, comprising applying to the plant an effective ethylene response-inhibiting amount of a compound of Formula I:
- 17
- wherein:
