摘要
用抗旱浸种剂和拌种剂复合处理玉米种子 ,在较低的土壤水分条件下 ,可提高玉米种子的出苗率和出苗速度 ,促进幼苗根系生长。同时能提高叶绿素含量和可溶性糖含量 ,降低游离脯氨酸含量 ,植株保水抗旱力明显增强。试验结果表明 ,出苗率、苗高、苗干重、根长、根干重、根体积、根冠比、叶绿素含量、可溶性糖含量、脯氨酸含量处理间均有显著差异 ,其中用浸种剂浸 8h和用 2 %拌种剂复合处理的效果最好 ,显著优于空白对照和 8h清水浸种处理。
Maize seeds were treated complexly by drought resistance seed-soaking drug and seed-dressing drug under drought stress. Results showed that drought-resistant pharmaceutics could promote seed germination and the growth of seedling root system ,increased the content of chlorophyll and soluble sugar ,reduced the content of proline,and have an obvious effect on keeping water ability of maize plant. There was remarkable difference among treatments in the rate of emergence,plant height,shoot dry weight,root length,root dry weight,root volume,root-cap ratio,the content of chlorlphyll,the content of soluble sugar and the content of proline. The treatment that seeds are soaked for 8 hours while dressed for 2 percent were the best effective.
