摘要
红麻种子超干燥后，种子生活力明显下降。经五种不同的CB预先回湿方法（a、25％PEG处理；b、100％RH二天；c、40％～60％RH一周；d、40％～6O％RH一周加80％～90％RH二天；e、水浸二天）处理后，除水浸二天处理其它四种方法处理与对照相比均有极显著的效果。发芽势、发芽率、发芽指数和活力指数均显著地高于对照，其中以25％PEG处理和40％～60％RH一周加80％～90％RH二天的处理效果最佳，且两者间无显著性差异。
Seed viability decrease obviously after the seed was ultradried. The ultradried seeds were treated with five different methods(a. 25 % PEG, b. 100% RH for two days, c. 405- 60% RH for one wekk plus 80N - 90% RH for two days, e. immersed in waterfor two days)- Seed viability increased significantly after seeds were treated. The best treatments are 25% PEG and 40%- 60%RH for one week plus 80% - 90% RH for two days , and there was no significant difference between the effect of these two meth-ods.
