研究Ca2+和钙调素(CaM)拮抗剂W 7[N-(6-am inohexyl)-5-chloro-1-naphthalene su lfonam ide]对辣椒幼苗抗冷性的影响,结果表明:Ca2+浸种处理显著降低了低温胁迫下叶片电解质渗透率和MDA含量,提高了SOD、POD活性和可溶性蛋白质、可溶性糖的含量,而W 7浸种处理显著提高了低温胁迫下辣椒幼苗叶片电解质渗透率和MDA含量,降低了SOD、POD活性和可溶性蛋白质、可溶性糖的含量,说明Ca2+.CaM信使系统在辣椒幼苗抗冷调控过程中起着重要的作用。
【英文摘要】
The effect of seeds soaking with Ca2+ and calmodulin antagonist W7 on chilling resistance of pepper seedlings were studied.Seed soaking with Ca2+ solution obviously decreased the contents of malondialdehyde(MDA) and electrolyte leakage,increased the activities of superoxid dismutase(SOD),the peroxide enzyme(POD) and the content of soluble protein and soluble sugar of pepper leaves,seed soaking with W7 distinctly enhanced the contents of MDA and electrolyte leakage,reduced the the activities of SOD,POD and t...
