摘要
研究了赤霉素(GA3)预处理结合瓶插液(蔗糖+8-羟基喹啉)使用对洋桔梗(Eustoma grandiflorum)切花的保鲜效应。结果表明,25 mg/L GA3预处理配合30 g/L蔗糖+100 mg/L 8-羟基喹啉瓶插液处理能延长洋桔梗切花的瓶插寿命,增加花枝鲜重,改善水分平衡值,延缓可溶性蛋白质含量的下降,还可以提高保护酶过氧化物酶(POD)和超氧化物歧化酶(SOD)的活性。
The preservative effect of GA3pretreatment combined with vase solution(sucrose and 8-hydroxyquinoline) on Eustoma grandiflorum cut flowers were evaluated. The results showed that the vase life of cut flowers could be extended by 25mg / L GA3pretreatment combined with vase solution containing 30 g / L sucrose and 100 mg / L 8-hydroxyquinoline. Meanwhile,the fresh weight of flowering branch was increased; moisture balance was improved; degradation of soluble protein was delayed; and activity of POD, SOD in cut flowers was all increased.
