the effect of ethanol and cycloheximide on the vase life of cut flowers alstroemeria (alstroemeria hybrida)

Alstroemeria is one of the most beautiful flowers in the family alstroemeriaceae.one of the major problems of this cut flower is short life ofleaves, this fact reduces the economic value of this cut flower. abscission ofpetal before wilting is also considered as one of the most important problemsof this flower. petals of this flower are very sensitive to ethylene. a factorialexperiment based on completely randomized design was conduced to studythe interaction effect of ethanol and foliar spraying cycloheximide (chi) onthe vase life and postharvest characteristics of alstroemeria with four levelsof ethanol (0, 2, 4 and 6%) and foliar spraying chi in three levels (0, 0.5, 1mm) in three replications and 36 experimental plots with five cut flowersper plot. anova showed that the effects of interaction ethanol and chi onthe measured traits were significant at 5% for the vase life and 1% for theother traits. results showed that the treatment of 1 mm chi and 6% ethanolwith 15.94 days has the maximum vase life in compared with the control(10.74 days).
