摘　　要：壳低聚糖是小分子量的壳聚糖降解产物,目前在生产和生活中得到广泛应用。本文研究了用亚硝酸降解法制备的壳低聚糖对普通农作物种子生理和生化指标的影响。结果表明:不同浓度的壳低聚糖可不同程度地改善绿豆的生理生化指标,其中,以1.0 %浓度的壳低聚糖溶液效果最好。1.0%的壳低聚糖可不同程度地提高种子的发芽指数、活力指数和过氧化物酶活力,对种子萌芽和幼苗均有一定的促生长作用。因此,壳低聚糖作为一种新型植物生长调节剂,可以在农业生产中发挥一定的作用。Chitin-oligosaccharides are decomposition products of chitosan, which are small in molecular weight, and used in human production and living widely. In this study, a kind of chitin-oligosaccharide was prepared with its effects on some physiological indexes of crop seeds including, for example, soya bean, red bean, cowpea, wheat, among others determined. The results showed that chitin-oligosaccharides at different concentrations can improve germination, vigor indexes and peroxidase activity. Meanwhile the oligosaccharides increased the seed germination potential, germination rate and physiological indexes of seedlings to a certain degree. Chitin-oligosaccharides, as a new plant growth regulator, can play a certain role in agricultural production.
