| 摘 要： | 研究了不同Ca2 浓度处理和Ca2 信号抑制剂对低温下辣椒幼苗叶片中3种主要渗透调节物质的影响。结果表明,外源10mmol/LCa2 能明显地增加辣椒幼苗叶片可溶性蛋白质、可溶性糖和脯氨酸含量。采用Ca2 螯合剂EGTA和钙调素拮抗剂W 7N-(6-氨基己基)-5-氯-1-萘磺胺]对辣椒幼苗低温处理后,辣椒幼苗叶片中可溶性蛋白质、可溶性糖和脯氨酸含量降低。以上结果说明Ca2 信号系统参与了调节辣椒幼苗抗寒过程中渗透物质的合成。

| Abstract: | Effects of different concentrations of Ca2 and inhibitors of Ca2 signal system on some osmolytes,including soluble protein,soluble sugar and proline in pepper under low temperature stress were investigated.The results indicated that extraneous calcium(10mmol/L) treatment could markedly increase the content of soluble protein,soluble sugar and proline.Moreover,addition of Ca2 chelating agent EGTA or calmodulin antagonist W7 could markedly decrease the content of soluble protein,soluble sugar and proline.Taken together the above results,it is suggested that Ca2 signal system may be regulated by change of some osmolytes in Pepper under low temperature. |
