چکیده
leaf yellowing is a major problem in postharvest of alstroemeria cut flowers. for delaying of leaf yellowing and increasing flower quality a completely randomized factorial design was carried out on the alstroemeria cut flowers (‘fuji’ cultivar). in this research ethanol (0, 2, 4, 6%), ga3 (0, 50, 100, 150 mg/litre) in two methods (pulse and continuous) were investigated on the flower vese life and other qualitative traits. there is 4% sucrose in all treatments except control. result revealed that continuous treatment had more effect on the vase life and quality of flowers than pulse treatment. 4% ethanol prolonged vase life and increased solution uptake. increasing ga3 concentration in holding solution prolonged vase life and coused better retention of quality of cut flowers. however had no significant difference in 100 &150 mg/l ga3 in flower vase life, solution uptake and fresh weight? moreover ga3 in pulse treatment had more effect than continuous treatment on better retention of chlorophyll.
