摘 要:研究不同浓度的壳聚糖溶液对酸浆种子萌发及幼苗生长的影响。分别用0、0.1、0.2、0.3、0.4、0.5 g/L的壳聚糖(CTS)溶液处理酸浆种子。结果表明,不同浓度的壳聚糖溶液处理后,低浓度的壳聚糖溶液(小于0.3g/L)显著增加酸浆发芽势、发芽率、活力指数、生物量、叶绿素含量、可溶性蛋白含量、可溶性糖含量、硝酸还原酶活力、根系活力。当为高浓度壳聚糖溶液时(0.4、0.5g/L)表现出抑制效应,其中以0.2g/L壳聚糖溶液处理效果最好。关键词:壳聚糖;酸浆种子;促进;种子萌发;幼苗生长8552
Effect of Chitosan on Seed Germination and Seedling Growth
of Physalis alkekengi
Abstract: for explore the effect of chitosan solution on seed germination and seedling growth. Treating the Physalis alkekengi seed with of 0,0.1,0.2,0.3,0.4,0.5 g/L Chitosan solution. The results showed that, the germination potential and rate, the seed vitality index ,biomass ,the content of chlorophyll, soluble protein, soluble sugar, the activity of nitrate reductase and root activity in leaves were increased when compared to the control after low concentration of chitosan solution treatment. The results were reverse, when there is high concentration of chitosan solution treatment. And 0.2g/l was the optimal concentration.
Key words: Chitosan; Physalis alkekengi seed;
