| 摘 要： | 以槟榔盆栽幼苗为试验材料,研究低温对其生理生化特性的影响。结果表明:随着低温处理时间的延长,幼苗受害指数增大,细胞质膜透性、丙二醛含量和脯氨酸含量均有不同程度的升高;SOD酶活性出现先上升而后下降的变化趋势,POD酶活性整体呈"S"形变化趋势,两者可能在逆境处理过程中具有互补作用。

| Abstract: | The effect of low temperature on the physiological and biochemical characteristics of areanut(Areca catectu L.) seedlings was studied.The result showed that the injury index,membrane leakage,MDA content and proline content in the leaves of areanut seedlings increased along with the extension of low temperature stress time.When the time of low temperature stress prolonged,the Superoxide Dismutase(SOD) activity first increased and then decreased gradually,while the change of peroxidase(POD) activity showed S ... |
