初步探讨了ZnCl2 对月季切花瓶插保鲜作用及其生理生化基础 结果表明 :与对照 (去离子水 )和基本液 (2 0g/L蔗糖 +50 0mg/L柠檬酸 +2 50mg/L 8-羟基喹啉 +2 5mg/L硝酸银 )相比 ,经ZnCl2 改良液处理的月季切花花枝硬挺 ,弯头减少 ,蓝变减轻并延迟 ,平均瓶插寿命延长 10 %～6 0 % ,尤以 10mg/L的ZnCl2 改良液效果最好 ZnCl2 改良液处理增加花枝鲜重 ,明显降低月季切花衰老过程中花瓣花青素含量下降的幅度 ,并显著延缓花瓣和叶片膜相对透性的增加
The effects of ZnCl2 on the preservation of cut rose vase and its physiological and biochemical basis were discussed preliminarily. The results showed that compared with control (deionized water) and basic solution (20g / L sucrose + 50 0mg / L citric acid + 250mg / L 8- Compared with the control, the cuttings of cut rose treated with ZnCl2 modified solution were stiff, the elbows were reduced, the blue stains were reduced and delayed, the average vase life was prolonged by 10% ~ 60%, especially 10mg / L ZnCl2 modified liquid best ZnCl2 modified liquid to increase the fresh weight of flowering branches, significantly reduce the rate of petal anthocyanin content during the senescence of cut rose, and significantly delay the increase of the relative permeability of petals and leaf membrane
