摘    要:为了研究壳聚糖浸种处理棉种对种子萌发和幼苗生长的影响。分别用0.5 g/L、1 g/L、1.5 g/L、2 g/L、2.5 g/L、3 g/L的壳聚糖溶液浸种处理棉花种子。结果表明,壳聚糖浓度为1.5 g/L,棉种的发芽率提高16.56%,出苗时间提早0.8天,出苗率提高15.53%,株高提高11.85%,叶片鲜重提高9.63%,幼苗的淀粉酶含量提高13.79%,叶绿素含量提高4.94%,脯氨酸含量提高13.28%,过氧化氢酶活提高7.21%。由此得出,适宜浓度壳聚糖溶液处理能促进种子萌发和幼苗生长,其中最适浓度为1.5 g/L,通过研究壳聚糖对棉花生长的影响,为其在农业上的应用研究提供新思路。

Abstract:The effect of chitosan on seed germination and seedling growth. Treating the cotton seed with 0.5 g/L, 1 g/L, 1.5 g/L, 2 g/L, 2.5 g/L, 3 g/L of chitosan. The results showed that, when the concentration of chitosan reached 1.5 g/L, the germination rate increased by 16.56%, in the same time the seedling emergence time of cotton was 0.8 day earlier than the control group, and the emergence rate, plant height, fresh weight had increased by 15.53%, 11.85% and 9.63%, and the content of amylase, chlorophyll content, proline content, catalase activity had increased by 13.79%, 4.94%, 13.28% and 7.21%. Appropriate concentration of chitosan could promote seed germination and seedling growth of cotton and the promoting effect of the seed treated by 1.5 g/L was the highest. Above discussed in the paper providing a new insight into the application effects of chitosan in agriculture.
Keywords:chitosan  seed soaking  promote  seed germination  seedling growth
