以０．１０％～０．５０％的羧甲基壳聚糖（ｃａｒｂｏｘｙｍｅｔｈｙｌｃｈｉｔｏｓａｎ）处理玉米种子，可以明显提高种子的发芽势、发芽率和实生苗株高，并表现出与浓度有关。萌发种子胚乳的α－淀粉酶活性、α－淀粉酶同工酶及幼苗叶片叶绿素含量测定与分析结果表明，羧甲基壳聚糖能加速种子萌发过程中胚乳淀粉的水解，为种子萌发提供充足的养分，有利于幼苗生长。说明羧甲基壳聚糖对种子萌发及幼苗生长具有明显的生理调节功能
Treatment of corn seeds with carboxymethylchitosan at 0.10% ~ 0.50% could significantly improve seed germination potential, germination rate and seedling height, and showed a correlation with concentration. The α-amylase activity, the α-amylase isoenzyme and the chlorophyll content of the seedling leaves of the germinating seeds showed that the carboxymethyl chitosan could accelerate the hydrolysis of the endosperm starch during seed germination and provide adequate seed germination The nutrients are conducive to seedling growth. Carboxymethyl chitosan showed obvious physiological regulation on seed germination and seedling growth
