5种异裂菊属植物光响应模型拟合及光合特性研究
Light Response Model Fitting and Photosynthetic Characteristics of Five Heteroplexis Plants
摘要
Abstract
In order to elucidate photosynthetic characteristics and mechanism of adapting to karst adversity of endemic genus Heteroplexis in karst areas,taking five Heteroplexis plants as materials,four models were used to fit light response curves,and key photosynthetic parameters were analyzed.Results showed that curve of rectan-gular hyperbola model deviated greatly with measured value curve or could not reflect photoinhibition,which was not suitable for light response fitting of Heteroplexis plants.Curve of modified rectangular hyperbola model was similar to measured value curve and was most suitable for light response fitting of Heteroplexis plants.Het-eroplexis sericophylla had the best adaptability to strong light.Heteroplexis incana had the best shade tolerance.Heteroplexis microcephala had the strongest photosynthetic potential.Corresponding environmental factors should be adjusted to make Heteroplexisplants grow better.关键词
