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.
The present invention generally relates to methods of inhibiting ethylene responses in plants and plant materials, and particularly relates to methods of inhibiting various ethylene responses including plant maturation and degradation, by exposing plants to cyclopropene derivatives and compositions thereof wherein: 1) at least one substituent on the cyclopropene ring contains a carbocyclic or heterocyclic ring, or 2) a substituent contains silicon, sulfur, phosphorous, or boron, or 3) least one substituent contains from one to four non-hydrogen atoms and at least one substituent contains more than four non-hydrogen atoms.
A composition is provided that contains one or more cyclopropene and that contains one or more of
(AA) one or more plant growth regulator that is not a cyclopropene, or
(BB) one or more adjuvant selected from the group consisting of one or more surfactants, one or more alcohols, one or more oils, and mixtures thereof, or
(CC) one or more mixture of said (AA) and said (BB).
Also provided is a method that includes the step of contacting such compositions to one or more plants or plant parts.
