[目的]研究壳寡糖对小麦(Triticum aestivum)种子萌发及幼苗生长的影响.[方法]利用不同浓度壳寡糖处理小麦种子及幼苗,研究壳寡糖对小麦种子萌发及幼苗生长的影响.[结果]壳寡糖能够有效地提高小麦种子胚乳淀粉酶活力,提高胚根、胚芽的生长速率,促进小麦种子萌发;同时,壳寡糖还可提高小麦幼苗叶片叶绿素含量以及根系活力,促进幼苗生长.其中浓度为0.1 μg/ml壳寡糖的促进作用最为明显.[结论]壳寡糖具有促进小麦种子萌发及幼苗生长的作用.该研究可为壳寡糖的应用提供理论支持.%[ Objective ] The research aimed to study the effects of chito-oligosaccharide on wheat seed germination and seedlings growth.[ Methods ] Treating wheat seed and seedling with different consistency of chito-oligosaccharide, the effect of chito-oligosaccharide on wheat seed germination and seedlings growth was studied. [ Results ] The results showed that chito-oligosaccharide could improve the amylase activity of wheat seed, increase the growth-rate of root and bud, stimulate the seed germination. And at the time, it could improve the chlorophyll of the plants and the root activity, and accelerate the rate of wheat seedlings growth. Comparatively, the chito-oligosaccharide in concentrations of 0.1 μg/ml made the most obvious promotion effect. [ Conclusion] Chito-oligosaccharide can make a promotion effect on wheat seed germination and seedlings growth. The study can provide theoretical support for the applying of chito-oligosaccharide.
