Provided is a device for generation of cyclopropene compounds which is capableof achieving direct in situ preparation and application of cyclopropene compoundsinhibiting the action of ethylene which accelerates the ripening process ofplants, the device comprising a first storage part for storing precursors ofcyclopropene compounds ("cyclopropene precursors"), a secondstorage part for storing reaction reagents which convert cyclopropene precursorsinto cyclopropene derivatives via chemical reaction, and a spray part for sprayingthe cyclopropene derivatives produced by the chemical reaction between thecyclopropene precursors and the reaction reagents.
