| 摘 要： | 用0.1％、0.2％、0.3％、0.4％、0.5％五种浓度的壳聚糖溶液处理棉花种子12h,以蒸馏水浸种12h为对照.室温培养7d,每天自然光照8h,棉花种子的发芽率、发芽势、萌发指数、活力指数及α-淀粉酶活性、过氧化物酶活性和过氧化氢酶活性均比对照高,且随着壳聚糖浓度的增大各指标均呈先升高后降低的趋势,处理浓度为0.2％时,种子的发芽率、发芽势、萌发指数、活力指数及α-淀粉酶活性、过氧化物酶活性和过氧化氢酶活性分别提高了16.7％、3.17％、2.63、30.7、96.87％、37.42％、33.78％,效果最佳.

| Abstract: | Cotton seeds were soaked in chitosan solution of different concentrations(0.1%,0.2%,0.3%,0.4%,0.5%)for 12 hours in comparison with seeds in water.Then cultured them for 7 days at room temperature and 8 hours at natural light every day.Seed germination rate,germination power,germination index,vigor index and activity of a-amylase,POD and CAT were higher than the control.With the increasing of chitosan concentration,all indexes increaded at first and then decreased,When the concentration was 0.2%,the seed germination rate,germination energy,germination index,vigor index,a-amylase,POD and CAT activity were increased by 16.7%,3.17%,2.63,30.7,96.87%,37.42% and 33.78% respectively,and it was the optimum concentration. |
