| 摘 要： | 用PEG、PVA、KNO3、PEG KNO3、PVA KNO3对杂交籼稻汕优63 F1和特优559 F1人工老化种子进行引发效果研究,筛选最佳处理方法。结果表明:1.0%PVA 1.0%KNO3处理杂交籼稻种子1 d,引发效果最佳,发芽率显著提高。引发后,汕优63发芽率由74.7%提高到85.0%,特优559发芽率由73.7%提高到88.0%。活力指数、发芽势、苗高、苗重也均较未经处理的人工老化种子显著提高。

| Abstract: | Priming effects were studied on artificially aged indica rice Shanyou63 F1 and Teyou559 F1 seeds using PEG,PVA,KNO3,PEG KNO3,PVA KNO3 sollution with different concentrations.The result showed that,the best priming effect was obtained at the treatment of 1.0 %PVA 1.0 %KNO3,soaking 1 day.The germination percentage of Shanyou63 and Teyou559 was raised from 74.7 % to 85.0 % and from 73.7 % to 88.0 % respectively after priming.Vigor index,germination rate,seedling fresh weight,seedling height increased significantly compared with check of no priming treatment on the artificially aged seed. |
