摘要
测定了相近环境条件下 ,高密度和低密度种群的北美车前在不同生长时期的叶绿素a/b值、过氧化物酶 (POD)活性、可溶性糖及脯氨酸 (Pro)的含量 .结果表明 ,各个生长时期的北美车前 ,高密度种群的叶绿素a/b值低于低密度种群 ,而POD活性、可溶性糖含量和叶片游离脯氨酸含量都高于低密度种群 .并分析了 4种生理指标的变化与种群对环境适应间的相关性 .
In this paper,the physiological indices of Plantago virginica including chlorophyll a/b,the activity of POD,the contents of soluble sugar and free proline at 1 360 individuals/m+2 and 60 individuals/m+2 were tested. The results showed that compared with the populations at lower density, the populations at higher density had lower chlorophyll a/b, while their activity of POD,the contents of soluble sugar and free proline were higher. The relationship between the physiological indices and their environmental adaptability at different population densities was discussed.
