摘要:
以结缕草、假俭草、钝叶草3种暖季型草坪草为试验材料，采用人工低温处理，对不同处理温度叶片的细胞膜相对电导率、可溶性蛋白含量、SOD活性、POD活性进行测定分析。结果表明：随着处理温度的降低，3种暖季型草坪草叶片的细胞膜相对电导率呈上升趋势，细胞膜稳定性表现为结缕草>假俭草>钝叶草；草坪草叶片的可溶性蛋白含量呈升高趋势；草坪草叶片的SOD、POD活性均呈先升高后降低的趋势；0～-10℃为3种草坪草遭受低温胁迫的敏感区域。3种暖季型草坪草的抗寒性强弱表现为：结缕草>假俭草>钝叶草。
Abstract:
With the three warmseason turfgrass Zoysia japonica，Eremochloa ophiuroides and Stenotaphrum secundatum as experimental materials，using artificial low temperature treatment，measured and analysed the difference among leaves which was disposed under various low temperatures including relative electric conductivity of cytomembrane，the content of water-soluble protein and the activity of SOD,POD.The results showed that with the reduce of the temperature，relative electric conductivity of plasma membrane increased in the three warmseason turfgrass leaves，the plasma membrane stability showed that Zoysia japonica＞Eremochloa ophiuroides＞Stenotaphrum secundatum，the tendency of water-soluble protein in the turfgrass leaves presented rise，the activity of SOD,POD in the turfgrass leaves increased at first and then decreased，the range of sensitive areas under low temperature stress in three turfgrass was between 0℃ and-10℃.And it concluded that the cold resistance of the three warmseason turfgrass was as follows: Zoysia japonica＞Eremochloa ophiuroides＞Stenotaphrum secundatum.
