Some characteristics of tuberose as affected by pre-harvest application of calcium chloride and gibberillic acid
Mortazavi, S.N. | Bagheri, F. | Bahadoran, M.
In the present study the effect of gibberellic acid (GA3) and calcium chloride (CaCl2) sprays (0, 150, 300 and 450 ml L-1), applied 25 and 15 days before harvesting, on physiological and morphological characteristics of tuberose ‘Pearl Double’ was studied. Cut flowers were harvested and transported to the laboratory where they were placed in distilled water. The experiment considered some parameters for evaluation, such as relative water content of leaves and petals, water intake, percentage of open florets, electrolyte leakage, ethylene production, chlorophyll and carotenoid content. Results indicate that the best treatment was the combination of 150 ml L-1CaCl2 and 450 ml L-1GA3 for most of parameters
