摘要
通过对大花滨菊、金鸡菊、‘北美黄’北京夏菊、北京小菊4种菊科植物的株高变化、相对电导率、丙二醛含量、脯氨酸含量和可溶性总糖含量等生理生化指标的测定,评价了它们的抗旱性。综合各项指标,4种菊科植物之间的抗干旱能力有着明显的差异,其耐干旱能力由强到弱的排序依次为北京小菊、‘北美黄’北京夏菊、金鸡菊、大花滨菊。
In this paper, the soil moisture, plant height, the relative conductance of Chrysanthemum leucanthemum, Coreopsis, ＇North American yellow＇ Beijing summer Chrysanthemum, Beijing miniature Chrysanthemum, proline content and soluble sugar content of physiological and biochemical indicators of four ground cover plants of Compositae were determined, and the drought resistance was studied. On the basis of all indexes, four different varieties of drought-resistant between the ability have significant differences that Composite indicators, the ability of the resistance to drought from strong action to the weak is Beijing miniature Chrysanthemum, ＇North American yellow＇ Beijing Summer Chrysanthemum, Coreopsis, Chrysanthemum leucanthemum
