Effect of cobalt chloride on vase life and postharvest quality of cut tuberose (Polianthes tuberosa L.)

Mohsen Mohammadi*, Davood Hashemabadi and Behzad Kaviani

In order to evaluate the effect of cobalt chloride on vase life and postharvest of cut tuberose, an experiment based on complete randomized design with 4 levels of cobalt chloride (0, 200, 300, 400 mg l-1) in 3 replications was conducted. Statistical analysis showed that the effect of cobalt chloride on measured traits was significant at 5 and 1% probability level. Mean comparison of the data showed that the 300 mg l-1 of cobalt chloride had the highest effect on longer vase life (10.66 days), water absorption (1.53 ml g-1 F.W.) and loss of fresh weight (19.99 g). Also, the 400 mg l-1 of cobalt chloride showed the maximum effect on petal’s carotenoids (0.40 g) and proteins (31.10%).
