3个野生大豆与栽培大豆杂交后代品系的光合光响应曲线及模型拟合
Photosynthesis Light Response Curves of Three Hybrid Soybean Strains and Model Fitting
摘要
Abstract
In this experiment,three strains that were obtained by crossing Glycine soja Sieb.et Zucc.and Glycine max (L.) Men.were selected as the research objects and the male parent Glycane sofa.was used as control(CK).Four typical models of photosynthesis light response curve,such as rectangular hyperbolic model,non-rectangular hyperbolic model,modified rectangular hyperbolic model and exponential function model were adopted to fit the photosynthesis light response curves of the test materials.The aim was to determine the model's suitability used for hybrid soybeans and compare the differences in photosynthetic characteristics between the three strains and the male parent.The results showed that these four models could fit the photosynthesis light response curves of strain 0004,strain 0005,strain 9002 and CK (R2 ＞ 0.98).Because the rectangular hyperbola model,non-rectangular hyperbola model and exponemial equation model were unable to calculate maximum net photosynthetic rate (Pn max) and saturation point(Isat) of plants and the fining values were different from the measured values,the phenomenon of photoinhibition could not reflected either.Only the modified rectangular hyperbolic model could solve the questions mentioned above very well,which was suitable for this study.Through the comparison of the photosynthetic parameters of the four tested materials,the strain 9002 showed the best photosynthetic characteristics and the strongest light adaptability.关键词
