摘    要:采用培养皿发芽法,研究了NaCl胁迫、GA3+Ca2+混合处理和吸湿-回干处理对辣椒种子发芽的影响。结果表明:20~80 mmol/LNaCl胁迫处理辣椒种子,能提高种子发芽势、发芽指数和活力指数,但对发芽率影响不大;NaCl浓度超过80 mmol/L,随着处理浓度的升高,各发芽指标值均呈下降趋势。200 mg/L GA3+20 mmol/L Ca2+混合液浸种,可显著提高种子发芽势、发芽指数和活力指数。辣椒种子吸湿-回干处理24 h,种子开始发芽的时间提前,发芽势、发芽指数和活力指数显著提高。

关 键 词:辣椒  种子发芽  GA3+Ca2+混合处理  NaCl胁迫  吸湿-回干

Abstract:The effect of pepper(Capsicum frutescens L.) seed treatment with NaC1,GA_3+Ca~(2+) and hydration-dehydration on its germination was studied.The results showed that the vigor of germination,the germination index and vigor index were increased in the treatment of 20~80?mmol/L NaC1,but the germination percentage was not various;and with the increasing of NaCl concentration(≥80?mmol/L NaCl),the inhibition on germination increased significantly.The vigor of germination,the germination index and vigor index were significantly increased while the seeds soaked with the mixed solution 200 mg/L GA_3+20 mmol/L Ca~(2+) and treated with hydration-dehydration for 24 hour.
Keywords:Pepper(Capsicum frutescens L  )  Seed germination  Mixed solution of GA_3 Ca~(2 )
