植酸对月季切花瓶插寿命的影响

Effect of Phytic Acid on Vase Life of Cut Rose Flowers

摘要:

用0.13%和0.013%植酸对月季切花进行处理,探讨了植酸对月季切花瓶插寿命及衰老过程中一些生理生化指标的影响。结果表明,0.13%和0.013%植酸处理的切花,瓶插寿命分别延长了2.3 d和1.4 d。植酸处理抑制了O₂^-.含量的增加和POD活性的提高,从而减轻了O₂^-.对植物细胞的伤害即抑制丙二醛含量增加,同时抑制了可溶性糖含量的降低,改善了切花吸水状况,并最终延长瓶插寿命。其中, 0.13%植酸处理的效果较好。因此,植酸能够有效延长月季切花的瓶插寿命,可应用于月季切花的瓶插保鲜。

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.
