摘要
选取贵阳市露地生长3年以上的9种常见绿篱植物,测定不同低温(0℃、-5℃、-10℃、-15℃)处理下各植物叶片的相对电导率、可溶性蛋白质含量、可溶性糖含量、脯氨酸含量、SOD活性、POD活性、MDA含量等7个生理生化指标的变化,并通过隶属函数法进行抗寒性综合评价,结果显示,9种绿篱植物抗寒能力排序为:红花檵木>南天竹>狭叶十大功劳>小叶女贞>小叶黄杨>火棘>迎春>六月雪>洒金桃叶珊瑚。
The present experiment was conducted to study the physiological and biochemical indices of cold-resistance on 9 hedge in Guiyang. The 9 common hedge grown in Guiyang exposed for more than 3 years. The relative electrolyte leakage percentage, the content of soluble protein, proline and MDA, the activities of SOD and POD were determined under the treatments of low-temperature. A comprehensive evaluation of cold-resistance was given based on subordinate function value analysis. The results showed that the order of cold-resistance was Loropetalum chinense〉Nandina domestica〉Mahonia fortunei〉Ligustrum quihoui〉Buxus sinica〉Pyracantha fortuneana〉 Jasminum nudiflorum〉Serissa serissoides〉A ucuba japonica.
