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.
