摘　　要：用^(60)Co-γ射线辐射11个小麦品种的干种子,结果表明:1个品种处理的发芽势、发芽率、发芽指数比对照极显著降低;7个品种处理苗高比对照显著或极显著提高;11个品种处理的根长和活力指数比对照显著或极显著降低;8个品种处理根冠比较对照显著或极显著降低,9个品种处理的出苗率显著或极显著低于对照,9个品种处理的成活率显著或极显著低于对照,11个品种处理的单蘖率、叶长、叶宽、根长均比对照极显著降低,9个品种处理的单株越冬蘖比对照显著或极显著降低。7个品种处理的可溶性蛋白含量比对照显著或极显著降低;6个品种处理的丙二醛含量均比对照显著或极显著提高;10个品种处理的POD活性比对照显著或极显著提高。11 wheat varieties＇ s dry seeds were radiated by ^60Co-γ ray. The results showed that one variety＇ s germination energy, germination rate and germination index of treatment were significantly lower than those of control ;7 varieties＇ s length of buds of treatment were significantly or extreme significantly higher than those of control; 1 1 varieties＇ s length of root and activity index of treatment were significantly or extreme significantly lower than those of control;8 varieties＇ s root/bud of treatment were significantly or extreme significantly lowerer than control; 9 varieties＇ s seedling rate of treatment was significantly lower than that of control. 9 varieties＇ s plant survival rate of treatment was significandy lower than that of control. 1 1 varieties＇ s singal tiller rate,length of leaves, breadth of leaves, root length and winter tiller per plant of treatment were signifi- candy lower than those of control. 9 varieties＇ s winter tiller per plant of treatment was significantly or extreme significandy lowerer than control;7 varieties＇ s content of soluble protein of treatment was significantly or extreme significantly lower than control. 6 varieties＇ s content of pmpanedial of treatment was significandy or extreme significantly higher than control ; 10 varieties＇ s content of POD enzyme were significantly or extreme significandy higher than those of control.
