摘　　要：为筛选适宜在天津地区生长的彩叶植物,以6种彩叶植物为研究对象,分析了6项抗逆生理指标的差异。结果显示:红叶臭椿的可溶性糖含量(0.195%)最高,紫叶李(0.11%)最低;金叶榆的可溶性蛋白含量(13.07 mg/g)最高,紫叶矮樱(7.135 mg/g)最低;红叶碧桃的游离脯氨酸含量(51.954μg/g)最高,紫叶矮樱(37.900μg/g)最低;金叶榆的过氧化物酶(POD)活性(52.38U/(g·min))最高,紫叶矮樱(15.012 U/(g·min))最低;金叶槐的超氧化物歧化酶(SOD)活性(0.499 U/g)最高,紫叶李(0.341 U/g)最低;紫叶矮樱的丙二醛含量(0.027μmol/g)最高,金叶榆(0.003μmol/g)最低。隶属函数综合分析得出,6种彩叶植物适应性可分为4类,最适宜的为金叶榆和金叶槐;其次为红叶碧桃、红叶臭椿;第3类为紫叶李;第4类为紫叶矮樱。In order to screen suitable color-leaf plants to grow in Tianjin, the 6 kinds of color-leaf plants were regarded as theresearch objects, including Sophora japonica cv. Golden Stem, Ulmus pumila cv.Jinye and Ailanthus altissima Var. et al. Thedifferences of 6 cultivar＇s anti-stress physiological indexes were analyzed. The results showed that Ailanthus altissima（0.195%）had the highest soluble sugar, the lowest one was Prunus cerasifera Ehrhar f.（0.11%） ; the Ulmus pumila cv.Jinye （13.07 mg/g）had the highest soluble protein, and the lowest one was Prunus×cistena N.E.Hansen ex Koehne（7.135 mg/g）; the Amygdaluspersica f. （51.954 μg/g） had the highest free proline, and the lowest one was Prunus×cistena N.E.Hansen ex Koehne （37.9 μg/g） ;the Ulmus pumila cv.Jinye（52.38 U/（g·min） ）had the highest peroxidase activity（POD）, and the lowest one was Prunus×cistena N.E.Hansen ex Koehne（15.012 U/（g·min） ）; the Sophora japonica cv. Golden Stem（0.499 U/g）had the highestsuperoxide dismutase, the lowest one was Prunus cerasifera Ehrhar f.（0.341 U/g）; the Prunus×cistena N.E.Hansen ex Koehne（0.027 μmol/g）had the highest malondialdehyde, the lowest one was Ulmus pumila cv.Jinye（0.003 μmol/g）. According tocomprehensive analysis of the index membership function, the adaptability of 6 kinds of color-leaf plants could be divided intofour categories. One of the best categories included Ulmus pumila cv. Jinye and Sophora japonica cv. Golden Stem; the secondcategory were Amygdalus persica f. and Ailanthus altissima Var; the third category was Prunus cerasifera Ehrhar f.; the lastcategory was Prunus×cistena N.E.Hansen ex Koehne.
