| 摘 要： | 采用SPD根际注射结合叶面喷施的方法,研究了不同浓度(0、50、100、150、200 mg/L)外源SPD对小白菜生长及其生理生化特性的影响.结果表明,100～150 mg/L SPD诱导能显著提高盐胁迫下小白菜的株高、单株干重、单株鲜重和含水量等;降低叶片丙二醛(MDA)含量;增强叶片超氧化物歧化酶(SOD)、过氧...

| Abstract: | We studied the effects of exogenous SPD of different concentration 0,50,100,150,200 mg/L on the physiological parameters in Chinese cabbage by the method of rhizosphere and foliar spraying. The results were as follows:SPD of 100-150 mg/L significantly improved the plant height,plant dry weight,plant fresh weight and plant water content,reduced the malondialdehyde(MDA)content. enhanced superoxide dismutase(SOD),peroxidase(POD)enzyme activity of leaf,significantly increased the chlorophyll content and the net... |
