| 摘 要： | 研究了不同化学试剂NaOH、HCl、H2O2、KNO3及激素GA3处理对稗草种子萌发的影响.结果表明,不同化学试剂及激素GA3处理对稗草种子萌发率的影响存在较大差异.NaOH对其萌发促进作用最大,用1.5%NaOH溶液浸泡稗草种子24 h后,萌发率高达94.67%,显著高于对照(6.67%);HCl、H2O2、KNO3处理对稗草种子萌发虽有一定的促进作用,但萌发率均低于30%.GA3处理对稗草萌发有明显的促进作用,当浓度为800 mg/L时,萌发率为80%.

| Abstract: | The objective of this study was to find the best method of stimulating germination of Echinochloa crus-galli seed.Effect of different chemical agents,NaOH,HCl,H2O2,KNO3 and gibberellin on the germination of Echinochloa crus-galli seed was studied.Results showed that seeds immersed in NaOH with 1.5% concentration for 24 h obtain germination of 94.67%,which was significantly higher than that of control(6.67%).While other chemical agents such as HCl,H2O2 and KNO3enhanced germination of Echinochloa crus-galli s... |
