چکیده
Alstroemeria is one of the most beautiful flowers in the family Alstroemeriaceae. One of the major problems of this cut flower is short life of leaves, this fact reduces the economic value of this cut flower. Abscission of petal before wilting is also considered as one of the most important problems of this flower. Petals of this flower are very sensitive to ethylene. A factorial experiment based  on completely randomized design was conduced to study the interaction effect of ethanol and foliar spraying cycloheximide (CHI) on the vase life and postharvest characteristics of alstroemeria with four levels of ethanol (0, 2, 4 and 6%) and foliar  spraying CHI in three levels (0, 0.5, 1 mM) in three replications and 36 experimental plots with five cut flowers per plot. ANOVA showed that the effects of  interaction ethanol and CHI on the measured traits were significant at 5% for the vase life and 1% for the other traits. Results showed that the treatment of 1 mM CHI and 6% ethanol with 15.94 days has the maximum vase life in compared with the control (10.74 days).

تازه های تحقیق
  •  This study showed that the use of anti-ethylene compounds of CHI and ethanol has improved the vase life of cut alstroemeria;
  • ANOVA showed that the effect of cycloheximide × ethanol was significant on vase life (P< 0.05) and chlorophyll a and b, petal anthocyanin, °Brix, ratio of open florets, electrolyte leakage and dry matter (P<0.01);
  • Maximum vase life, chlorophyll a, chlorophyll b, °Brix is related to the treatment of 1 mM CHI × 6% ethanol;
  • The results showed that among different treatments, 1 mM CHI × 6% ethanol, 0.5 mM CHI × 4% ethanol and 0.5 mM CHI × 6% ethanol had the maximum increase of the vase life and characteristics that related to vase life. Therefore, the treatment of 0.5 mM CHI × 4% ethanol can be introduced as the best treatment.
