Physiological Adaptation of Pachysandra terminalis Sieb.et Zucc under Different Canopy Conditions
摘要
Abstract
The differences of leaf pigment content and photosynthetic ability of Pachysandra terminalis Sieb.et Zucc under different artificial canopy conditions were studied.The results showed that the contents of total chlorophyll,chlorophyll a,chlorophyll b and carotenoid in the leaves of BD2 and BD4 at the junction of forest edge and forest were significantly higher than those of the other leaves,especially the photosynthetic pigment content in the leaves of BD4 was significantly higher than the leaves of BD8 which was out of the forest(P ＜ 0.01).The chlorophyll a/b value in the leaves of BD8 and BD6 was close to 3,and the other Pachysandra terminalis Sieb.et Zucc leaves was (2.093 ±0.249)-(2.589 ±0.019).The contents of chlorophyll and carotenoid in the leaves was relatively low.The leaf photosynthetic rate of BD2 and BD4 at the junction of forest edge and forest was higher than that of BD5,BD8 and BD1.The leaf light utilization rate of BD2 was significantly higher than that of BD8 and BD5 (P ＜ 0.01) as well as BD1 and BD3 (P ＜ 0.05).The rate of leaf indoor photosynthetically active radiation in the leaves of BD4 was significantly higher than that of the other samples.Because of the high content of chlorophyll and suitable chlorophyll a/b value in leaves of BD2 and BD4,the leaves had dark green leaf color and healthier texture.Pachysandra terminalis Sieb.et Zucc was most suitable for planting in semi shade environment.Due to decreased chlorophyll content and increased transpiration rate in the leaves of BD8,the leaf color of Pachysandra terminalis Sieb.et Zucc appeared yellow green.关键词
