6-BA和 GA3配伍对玫瑰切花保鲜效果的影响

摘要

The effect of preservative containing 6-BA and GA3 on biochemical and physiology of cut rose flowers dur-ing senescence was studied .The results showed that combined treatment of these two kinds of growth regulator can prolong the vase life of cut flowers , increase the activity of POD , slow down the rate of protein degradation , reduce the content of proline and water loss , increase the fresh weight of roses , and delay the reduce of soluble sugar con-tent.But, it had no significant effect in maintaining the relative stability of membrane structure .%研究含6-BA和GA3的保鲜剂在玫瑰切花衰老过程中对其生理生化的影响，试验结果表明：该保鲜剂可延长玫瑰切花的瓶插寿命，增加POD活性，减慢蛋白质降解的速度，降低脯氨酸含量和水分散失，增加玫瑰花枝的鲜重，延缓可溶性糖含量的降低，但对维持膜结构的相对稳定性作用不大。
