| 摘 要： | 水稻幼苗遭遇冷胁迫（１℃，光照强度１５０μｍｏｌ·ｍ－２·ｓ－１）２ｄ，其叶片丙二醛（ＭＤＡ）含量明显增加，酸性磷酸酯酶活性也增加，同时无机磷含量也增加。３０ｍｍｏｌ／Ｌ的ＣａＣｌ２浸泡种子１ｄ则削弱了冷胁迫的这种作用。Ｈ２Ｏ２和甲基紫精（ＭＶ）均有刺激幼苗叶片和离体根质膜酸性磷酸酯酶活性的作用。 |
| 关 键 词： | 水稻幼苗；膜脂过氧化；膜磷脂脱酯化；冷胁迫 |
Membrane lipid peroxidation and de_esterification of membrane phosphatide in leaves of rice seedlings under chilling stress |
|
| Abstract: | After chilling stress at 1 ℃ under a PFD of 150 μmol·m-2·s-1 for two days, content of MDA, activity of acid phosphatase and content of soluble phosphorus in leaves all increasedMethod of rice seeds submerged in 30 mmol/L CaCl2 solution for one day reduced all the above changes induced by chilling stressThe activities of acid phosphatase in both leaves of seedlings and plasma membrane from roots in vitro were induced by both H2O2 and MV. |
| Keywords: | Rice seedlings membrane lipid peroxidation de-esterification of membrane phosp- hatide chilling stress |
