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。The effect of pepper（ Capsicumfrutescens L. ） seed treatment with NaC1 ,GA3 ＋ 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 NaCl, but the germination percentage was not various; and with the increasing of NaCl concentration（ ≥ 80 mmol/L NaCl）, the inhibition on germination increased significantly, Tne vigor of germination, the germination index and vigor index were significantly increased while the seeds soaked with the mixed solution 200 mg/L GAs ＋ 20 mmol/L Ca^2＋ and treated with hydration-dehydration for 24 hour.
