Abstract

In order to investigate pre-harvest application of calcium in hydroponic culture, a factorial experiment was conducted based on completely randomized design with four replications. The first factor CaCl2 and the second factor CaNO3 and both factors were applied in four levels (0, 0. 5, 1 and 1. 5% as foliage spray). For evaluation of associated traits with vase life, the produced flowers were kept in a vase solution containing 200 mg/L hydroxyquinoline sulfate with temperature conditions of 20 ° C. The results showed that vase life of flowers extended 6. 13 and 5 days by application 1% CaCl2 for Intens and Rosalin respectively. All treatments were effective in the increasing relative fresh weight of flower due to increase water uptake. The results also revealed that the calcium pretreatment delayed flowers senescence and maintained leaf protein and petal Anthocyanin content. Application of calcium resulted in a decrease in electrolyte leakage and malondialdehyde content in the cut flowers of both cultivars, providing evidence for delay of senescence in calcium-treated cut flowers. Also, results showed that calcium application significantly increased peroxidase (POD) and phenylalanine ammonia-lyase (PAL) of both cultivars. The maximum and the minimum PAL and POD activities were observed in resistant and sensitive cultivars, respectively. Taken together the results showed pre-harvest application of calcium (especially 1% CaCl2) might be promising approaches to improve postharvest performance of two cultivars of gerbera cut flowers.
