| 摘 要： | 以无土基质培育的狗牙根(Cynodon dactylon)为研究对象,研究了狗牙根对不同干旱胁迫处理的生理响应,以探讨工厂化培育下狗牙根合理的灌溉时间.结果表明,干旱胁迫导致叶片相对含水量降低,游离脯氨酸含量和超氧化物歧化酶活性增加,在干旱胁迫12 d以前复水的处理,叶片相对含水量和游离脯氨酸含量能恢复到未处理以前,在...

| Abstract: | A pot experiment was carried out determine the physiological response of Bermudagrass(Cynodon dactylon)to different drought stresses for selecting the appropriate time of irrigation by measuring the relative water content,content of free proline and superoxidase activity.The results of this study indicated that drought stress decreased leaf relative water content and increased the content of free proline.The re-irrigation in the 12 days after drought stress restored the relative leaf water content and free ... |
