Abstract:The influence of phytic acid (PA) on vase life and some physiological and biochemical indexes of rose cut flowers was studied. The results showed that the vase life of cut rose flowers prolonged 2.3 days and 1.4 days treated with 0.13% and 0.013% PA, respectively. After rose cut flowers were treated with PA, peroxydase (POD) activity increased and the contents of O2-. and malonaldehyde (MDA) decreased. The increment of soluble sucrose content improved water absorbing ability of cut flowers treated with PA, so that the vase life prolonged. The effect of 0.13% PA was better than that of 0.013% PA. Therefore, PA could prolong the vase life of cut rose flowers, and it would be widely used in fresh-keeping of rose cut flowers.
