摘要
为了解天津轻度盐碱地上彩叶植物的适应性,本试验以金叶槐、金叶榆、紫叶李、紫叶矮樱、红叶碧桃、红叶臭椿6种彩叶植物为试材,测定了其可溶性糖、可溶性蛋白、游离脯氨酸、丙二醛含量,以及POD、SOD活性。结果表明,金叶榆可溶性糖、可溶性蛋白含量、POD活性均最高,但丙二醛含量最低,分别为0.184%、13.758 mg/g、65.033 U/(g·min)、0.005μmol/g;金叶槐游离脯氨酸含量和SOD酶活性均最高(43.186μg/g,0.582 U/g)。综合隶属函数分析显示,适应性最强的为金叶榆(0.826)和金叶槐(0.729);其次为红叶臭椿(0.634)、红叶碧桃(0.592)和紫叶李(0.134);紫叶矮樱(0.009)适应性最差。
To understand the adaptability of colored plants on the light saline-alkali land in Tianjin, the physiological characteristicsof six kinds of colorful plants, such as Sophora japonica cv. Golden stem, Ulmus pumila cv. jinye, Prunus Cerasifera Ehrhar f.Prunus Salicina and Prunus×cistena, Amygdalus persica f. atropurpurea, and Ailanthus altissima Var. were reseached accordingto their soluble sugar, soluble protein, free proline,malondialdehyde content, POD, and SOD activity in leaves.The resultsshowed that the content of soluble sugar, soluble protein and POD of Ulmus pumila cv. jinye were the highest, and its content ofmalondialdehyde was the lowest （0.184%, 13.758 mg/g, 65.033 U/ （g · min） and 0.005 μmol/g respectively） . Free proline contentand SOD activity were the highest（43.186 μg/g, 0.582 U/g）in Sophora japonica cv. Golden stem The results of comprehensivemembership function analysis showed that Ulmus pumila cv.jinye（0.826）and Sophora japonica cv. Golden stem（0.729）havethe best adaptability, followed by Ailanthus altissima Var.（0.634）, Amygdalus persica f. atropurpurea（0.592）and PrunusCerasifera Ehrhar f.（0.134）, while Prunus × cistena（0.009）was the worst.
