PP_(333)、GA_3对麝香百合切花品质及叶绿素含量的影响初探

用PP3 3 3 、GA3 溶液分别对麝香百合进行叶面喷施处理 ,试验结果表明 :叶面喷施GA3 对百合花茎长度及花朵数的增加影响最显著的浓度为 2 0 0mg/L ,其次为 5 0 0mg/L ;叶喷PP3 3 3 对茎长增加以浓度 1 0 0mg/L显著 ,而对花朵数增加以 2 0 0mg/L显著。叶绿素含量以GA3 2 0 0mg/L浓度的最高 ,其次为GA3 5 0 0mg/L ,且GA3 处理叶绿素含量总体上高于PP3 3 3 。

A Study on the Influence of PP_(333) and GA_3 on the Quality and Chlorophyll Content of Lilium longiflorum Thunb

Lilium longiflorum Thunb was foliarly sprayed with PP 333 and GA 3 respectively. The results indicated: 200 mg/L of GA 3 had the most remarkable effect on the stem length and flower quality of Lilium longiflorum Thunb; the effect of 500 mg/L of GA 3 was the next; 100 mg/L of PP 333 had remarkable effect on the stem length, while 200 mg/L had remarkable effect on flower number; the chlorophyll content was the highest when treated with 200 mg/L of GA 3, the effect of 500 mg/L of GA 3 was the next; the chlorophyll content was higher when treated with GA 3 than that when treated with PP 333 in general.
