Abstract: (503 Views)
Shelf life and maintenance of quality after harvest of ornamental plants are very important. The present experiment was conducted as a factorial experiment in the form of a completely randomized statistical design to investigate the effect of different levels of gibberellin and thymol essential oil on flower life and postharvest quality of Alstroemeria flowers (Alstroemeria L. Inticancha Dark Purple). Experimental treatments included different levels of gibberellin (zero, 25, 50, and 100 mg L-1) and different levels of thymol essential oil (zero, 50, and 100 mg L-1). The highest vase life was observed in the treatment with 50 mg L-1 gibberellin and thymol (15 days), this treatment also caused an increase in the relative fresh weight and absorption of the solution in Alstroemeria flowers, while the lowest vase life, relative fresh weight and absorption of the solution were recorded in the control. The relative fresh weight showed an upward trend in the treatments with 50 mg L-1 gibberellin and thymol and 100 mg L-1 gibberellin and 50 mg L-1 thymol until the third day, after which a downward trend was observed. Moreover, a positive correlation was observed between the yellowing of the leaves and the electrolyte loss of the leaves. The most favorable appearance quality (least yellowing) was observed in the treatments with 50 mg L-1 gibberellin and thymol or without thymol. The treatments with 25 mg L-1 gibberellin and 100 mg L-1 thymol and 50 mg L-1 gibberellin and thymol or without thymol reduced the bacteria at the stem end. In carbohydrate analysis, these indices showed an upward trend with increasing thymol concentration in the treatments without gibberellin, while a downward trend was observed with increasing gibberellin concentration along with the thymol treatment of 100 mg L-1. Finally, the results of this experiment suggest the use of 50 mg L-1 gibberellin with 50 mg L-1 thymol or without thymol to increase postharvest longevity and reduce the yellowing of leaves.
