| 摘 要： | 用低聚壳聚糖溶液处理桑树种子和对桑树进行叶面喷施 ,结果表明 :0 5 %的低聚壳聚糖溶液处理桑树种子 ,可以提高桑树种子的发芽率、发芽指数和幼苗生长势 ,桑树喷施 0 5 %的低聚壳聚糖溶液可提高叶片的叶绿素含量 ,增强光合能力 ,降低硝酸还原酶和过氧化氢酶的活性 ,叶片的可溶性糖、粗蛋白的质量分数分别提高 8 7%、8 2 % ,叶片的单位面积质量也高于对照 ;用处理过的桑叶喂蚕 ,可以提高产茧量和茧质。

| Abstract: | The effect of chitooligosaccharides on mulberry seeds germination and physiological characters of mulberry were studied. The results showed that spraying 0 5% chitooligosaccharides solution on the trees can obviously increase germinating percentage, germinating index and vigor index of mulberry seeds. Chitooligosaccharides can obviously increase chlorophyll content and photosynthetic rate, enhance content of soluble sugar and crude protein of leaves, decrease the activity of catalase and nitrate reductase. Yield and quality of leaves were increased through spraying chitooligosaccharides on mulberry trees |
