| 摘 要： | 以市售甲壳丰(有效成分为壳聚糖,壳聚糖含量为30%)进行稀释,稀释倍数分别为100、200、300、400、500、600倍,以清水为对照,对番茄种子进行浸种处理,探索壳聚糖对番茄种子萌发及幼苗生长的影响.结果表明:番茄种子发芽势、发芽率、幼苗主根伸长量及根系活力均高于对照,其中稀释300倍的壳聚糖最有利于番茄种子的萌发,稀释400倍的壳聚糖最有利于促进主根的伸长及根系活力,且壳聚糖在一定范围内存在浓度效应.

| Abstract: | Tomato seed were soaked in different concentration of chitosan solution.The diluted times varied from 100 to 600 times.The chitosan solution of different diluted times explored the chitosan on the impact of tomato seed germination and the growth of seedlings.The results showed that the tomato seed germination rate,germination potential,main root length and root activity were higher than the control that treated with water.The chitosan with diluted 300 times heavily activate to the tomato seed germination an... |
