PLANT ETHYLENE RESPONSE INHIBITION COMPOUNDS AND COMPLEXES

摘要

The present invention generally relates to the regulation of plant physiolog y, in particular to methods for inhibiting the ethylene response in plants or plant products, and has three embodiments. The first embodiment relates to methods of minimizing impurities capable of reversibly binding to plant ethylene receptor sites during the synthesis of cyclopropene and its derivatives such as methylcyclopropene, thereby avoiding the negative effect s these impurities have on plants treated with cyclopropene and its derivative s. The second embodiment relates to complexes formed from molecular encapsulati on agents such as cyclodextrin, and cyclopropene and its derivatives such as methylcyclopropene, in addition to cyclopentadiene and diazocyclopentadiene and their derivatives, thereby providing a convenient means for storing and transporting these compounds capable of inhibiting the ethylene response in plants, which are reactive gases and highly unstable because of oxidation an d other potential reactions. The third embodiment relates to convenient method s of delivering to plants these compounds capable of inhibiting the ethylene response in the plants in order to extend their shelf life.
