"METHODS FOR MINIMIZING IMPURITIES ABLE TO CONNECT REVERSIBLY TO THE ETHYLENE RECEPTORS ON A PLANT AND TO PROVIDE A COMPOUND AND METHYLCYCLOPROPENE TO A PLANT TO INHIBIT AN ETHYLENE RESPONSE ON THE PLANT,". The present invention, in general, concerns the regulation of plant physiology, in particular methods for inhibiting the response to ethylene in plants or plant products and has three modalities. The first modality concerns Methods of minimizing impurities capable of reversibly binding to ethylene receptor sites in the plant during the synthesis of cyclopropane and its derivatives, such as methylcyclopropene, thus avoiding the negative effects that these impurities have on plants treated with cyclopropene and its derivatives. The second modality concerns complexes formed from molecular encapsulating agents, such as cyclodextrin and cyclopropene and their derivatives such as methylcyclopropene, in addition to cyclopentadiene and diazocyclopentadiene and their derivatives thus providing convenient means to store and transport these compounds capable of inhibit the response to ethylene in plants, which are reactive and highly unstable gases because of oxidation and other potential reactions. The third modality concerns convenient methods of providing plants with these compounds capable of inhibiting the response to ethylene in plants in order to prolong their shelf life.
