| 摘 要： | 采用营养液水培系统,以花叶万年青为试材,用叶面喷施的方法,研究了外源水杨酸对根际低氧胁迫下花叶万年青的几个逆境指标的影响。结果表明:低氧胁迫下花叶万年青叶片超氧化物歧化酶(SOD)、过氧化物酶(POD)、丙二醛(MDA)的含量、细胞质膜透性均高于对照,外源SA明显抑制MDA的积累,降低了细胞膜透性,显著增强超氧化物歧化酶(SOD)、过氧化物酶(POD)的活性。说明SA作为化学诱抗剂,可抑制低氧胁迫下花叶万年青体内ROS的产生,提高抗氧化酶的活性,降低膜酯过氧化水平,从而提高植株对低氧胁迫的抵抗能力。

| Abstract: | By means of a system of nutrient solution culture,Dieffenbachia was used to study the effect of foliar application of exogenous salicylic acid(SA) on stress indexes species Dieffenbachia under hypoxia stress.The results showed that the content of superoxide dismutase(SOD),peroxidase(POD),malonaldehyde(MDA ),membrance permeability under root-zone hypoxia stress were higher than the control.However,the level of ascorbic acid(AsA) were decreased.Exogenous SA significantly decreased the content MDA,increased th... |
