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。
Under cold stress (1 ℃, light intensity 150μmol · m-2 · s-1) for 2 days, the content of malondialdehyde (MDA) and the activity of acid phosphatase in rice seedlings also increased and the content of inorganic phosphorus also increased. 30mmol / L CaCl2 immersion seeds 1d weakened this effect of cold stress. Both H2O2 and methyl viologen (MV) stimulated the activity of acid phosphatase in the leaf and exudative rhizosphere of seedlings.
