该试验于1993~1994年在山东农业大学校内以4个水、陆稻为材料,研究了水分胁迫下秧苗的生理效应。结果表明,水分胁迫下秧苗素质明显下降,细胞膜受到破坏,相对电导率、丙二醛含量及脯氨酸含量都显著地增加,水、陆稻对此反应有明显差异。在水分亏缺的情况下,陆稻秦爱与水稻中花2号等相比,秧苗体内水分含量相对稳定、膜受害较轻,丙二醛含量增加缓慢、增量较小,然而脯氨酸含量却迅速显著地积累。植株体内丙二醛、脯氨酸含量的变化,可作为水、陆稻抗旱性鉴定的生理指标。
The experiment from 1993 to 1994 in Shandong Agricultural University, four water, paddy rice as material, to study the physiological effects of seedling under water stress. The results showed that under water stress, the quality of seedlings decreased obviously, the cell membrane was damaged, the relative conductivity, MDA content and proline content increased significantly. In the case of water deficit, compared with rice Zhonghua 2, Qin A had a relatively stable water content in the seedlings, the membrane damage was lighter, the content of malondialdehyde increased slowly and the increase was smaller, but proline The content is rapidly and significantly accumulated. The changes of malondialdehyde and proline content in plants can be used as physiological indexes for drought resistance identification of water and Upland rice.
