| 摘 要： | 以鲁花11号花生（Arachis hypogaeaL．）种子为试验材料，在温室条件下研究不同浓度的冠菌素浸种，对干旱胁迫下花生幼苗叶片渗透调节物质及膜脂过氧化的影响。结果表明：干旱胁迫下，冠菌素可提高花生幼苗叶片主要渗透调节物质一可溶性糖、可溶性蛋白质和游离脯氨酸的含量，且随着胁迫时间的延长，增幅加大；花生幼苗叶片丙二醛（MDA）含量明显减少。冠菌素浸种浓度以0．01μmol／L的抗旱效果最好。研究表明冠菌素对提高花生幼苗的抗旱性具有积极作用。

| Abstract: | The peanut （Arachis hypogaea L. ） -- Luhua 11 was used for the material in this ex- periment. Peanut seeds were soaked with different concentration of COR. Peanut seeds were planted in greenhouse condition. In three leaves period, PEG was poured into soil to have a drought stress environment. The results showed that, under drought stress, osmolytes of peanut seedling leaves which were treated with COR were increased, and the content increased more and more along with the increase of stress time. The content of MDA in peanut seedling leaves were reduced. In these treatments, the best concentration of COR was 0.01μmol/L. Studies showed COR had positive significance for peanut seedling to improve drought-resistance. |
