盐胁迫对不同品种辣椒种子萌发特性的影响

Effect of Salt Stress on Germination Characteristics of Different Pepper Varieties

研究了NaCl胁迫对10个辣椒品种种子发芽的影响。结果表明,低盐浓度对辣椒种子萌发有促进作用,随着NaCl胁迫浓度的增大,对种子萌发的抑制作用明显增强,在供试的10个辣椒品种中,不同品种辣椒种子萌发受盐胁迫抑制的程度不同,“美国超大牛角王”、“特大牛角椒”和“大牛角椒”为耐盐品种,“保椒耐寒二号”不耐盐,其他品种耐盐性中等。

The effects of salt stress on the seed germinations of 10 pepper varieties were studied. The results showed that low salt concentration had a stimulating effect on germination. As NaCI concentration rose, the inhibitive effects on the seed germinations obviously increased. The seed germinations of the ten pepper varieties were differently inhibited by the stress ＂Meiguochaodaniujiaojiao＂, ＂Tedaniujiaojiao＂ and ＂Daniujiaojiao＂ were tolerant to salt, ＂Baojiaonaiyan 2^# ＂ were not tolerant and the other were moderately tolerant.
