| 摘 要： | 用不同浓度的聚乙二醇(PEG)、氯化钙(CaCl,2)、水杨酸(SA)溶液对不同质量的辣椒种子进行处理,它们对辣椒种子的发芽势和发芽率的影响差异不显著,但对辣椒种子活力的促进作用有一定的差异.对于高质量的辣椒种子来说,CaCl,2和SA对种子活力的提高显著好于PEG;对于低质量种子来说.虽然SA和PEG对种子活力的促进作用不如CaCl,2,但这3种渗透调节剂最佳处理组合之间对种子活力的影响差异不显著.另外,SA和CaCl,2可使辣椒种子有较强的抗逆性,PEG的抗逆效果次于SA和CaCl,2.

| Abstract: | Capsicum seeds were treated with different concentration of PEG,CaCl2 and SA respectively.No difference was found among the influence of PEG,CaCl2 and SA on capsicum seed germination potential and germination capacity,but some difference was found on seed vigor.For new capsicum seeds,there was the same effect between CaCl2 and SA on seed vigor,which was better than PEG.For aged capsicum seeds,there were no obviously differences among the influence of SA,PEG and CaCl2.The result indicated that SA and CaCl2 h... |
