超级高产小麦旗叶荧光动力学研究
Studies on the Chlorophyll Fluorescence Kinetics of the Flag Leaf of the Super High-yield in Wheat
摘要
Abstract
The objective of this study was to investigate the photosynthesis and fluorescence kinetics characteristics of the flag leaf of the super wheat varieties, and to provide a theoretical basis for breeding of the super yield varieties in wheat. Linmai4 a super yield variety, was used to investigate the parameters in the photosynthesis and fluorescence kinetics of the flag leaf. This was done using a CI-301 photosynthesis system and a FMS-2 chlorophyll fluorescence system in the field experiment. yieResults show that, compare with the comon high-yield varieties of Wanmai52 and Yannongl9, the photosynthetic parameters of photosynthetie rate, light saturation point, CO2 saturation point and carboxylase efficiency were high , and the compensation points of light and CO2 low for Linmai4; and its parameters value of photosynthetic system working about the actual photochemical efficiency of PSII(Φ PSII) ,the photochemical quenching (qP) ,the efficiency of reactive center stimulation energy capture of PSII( Fv/Fm) , the ratio of the variable to minimal fluorescence of PSII (Fv/F0) , and the electron transport rate (ETR) were high,and the (non photochemical quenching (NPQ) low. This proved that the photosynthetic system working ability is stronger, and working efficiency higher for Linmai4, and guarantee of proceeding of the photosynthesis efficiently for the flag leaf, and which could provide sufficient energy and carbohydrates for the seed filling.关键词
