Abstract
A method of inhibiting an ethylene response in a plant is disclosed herein. The method comprises applying to the plant an effective ethylene response-inhibiting amount of diazocyclopentadiene (DACP). Derivatives of DACP given by Formula (I) below may also be employed: ##STR1## wherein: n is from 1 to 4; and R is selected from the group consisting of halogen, hydroxy, C1-C4 alkyl, C1-C4 alkoxy, carboxy, and amino. DACP is preferred. Also disclosed are methods of inhibiting abscission in plants and methods of prolonging the life of cut flowers.
Claims20
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) below:
- ##STR3## wherein:
- n is from 1 to 4;
- and
- R is selected from the group consisting of hydrogen, halogen, hydroxy, C1-C4 alkyl, C1-C4 alkoxy, carboxy, and amino.
A method of inhibiting abscission in a plant, comprising applying to the plant an effective abscission-inhibiting amount of a compound of Formula (I) below:
- ##STR4## wherein:
- n is from 1 to 4;
- and
- R is selected from the group consisting of hydrogen, halogen, hydroxy, C1-C4 alkyl, C1-C4 alkoxy, carboxy, and amino.
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) below:
- ##STR5## wherein:
- n is from 1 to 4;
- and
- R is selected from the group consisting of hydrogen, halogen, hydroxy, C1-C4 alkyl, C1-C4 alkoxy, carboxy, and amino.
