摘要: 为比较不同种类彩叶植物在中重度盐碱地上的表现,通过对天津市滨海新区6种常见彩叶植物(金叶槐、金叶榆、紫叶李、紫叶矮樱、红叶碧桃、红叶臭椿)叶片的可溶性糖含量、可溶性蛋白含量、游离脯氨酸含量、POD活性、SOD活性、丙二醛含量的测定与分析,研究了它们的植物生理特性。结果显示:金叶槐的SOD活性最高,金叶榆的POD活性最高,它们的丙二醛含量最低。紫叶李的可溶性糖含量、SOD活性和游离脯氨酸含量最低,紫叶矮樱的丙二醛含量最高,可溶性糖含量、可溶性蛋白质含量和POD活性最低,红叶碧桃的游离脯氨酸含量最高,红叶臭椿的可溶性糖和可溶性蛋白质含量最高。综合分析显示,在中重度盐碱地上6种彩叶植物的生长由强到弱依次为: 金叶榆与金叶槐、红叶碧桃与红叶臭椿、紫叶李、紫叶矮樱。

Abstract: In order to compare the suitable varieties of colorful leaf tree for cultivation in severe saline-alkali soils, the soluble protein, soluble sugar, free proline, malondialdehyde content, membrane permeability, SOD, POD enzyme activity and other physiological and biochemical indexes in leaves were determined with six varieties(Zi Ye Li, Zi Ye Ai Ying, Jin Ye Yu, Jin Ye Huai, Hong Ye Chou Chun, Hong Ye Bi Tao)from 5 regions of Binhai in Tianjin. The results showed that SOD activity in Jin Ye Yu was the highest; POD enzyme activity in Jin Ye Yu was the highest; the malondialdehyde content in Jin Ye Huai and Jin Ye Yu was the lowest;the content of soluble protein and free proline content and SOD activity in Zi Ye Li was the lowest; the malondialdehyde content in Zi Ye Ai Ying was the highest; the content of soluble protein and soluble sugar and POD enzyme activity in Zi Ye Ai Ying was the lowest; the content of free proline in Hong Ye Bi Tao was the highest;the content of soluble sugar and the soluble proline in Hong Ye Chou Chun was the highest. In conclusion, the growth characteristics of the colorful leaf trees from strong to weak was that of Jin Ye Yu and Jin Ye Huai, Hong Ye Bi Tao and Hong Ye Chou Chun, Zi Ye Li, and Zi Ye Ai Ying.
