不同受涝模式下水稻抽穗开花期荧光参数的日变化规律
The Impact of Varying Farmland Water Logged of Rice to the Parameters of Diurnal Chlorophyll Fluorescence Kinetics in Heading and Flowering Stage
摘要
Abstract
Set four different modalities farmland water logged (tillering stage to heading and flowering stage of three successive reproductive stages water logged, jointing booting stage to heading and flowering stage of two successive reproductive water logged, heading and flowering stage of maintaining a smaller amount of leakage water logged, heading and flowering stage of maintaining a larger amount of leakage water logged) to study the impact of varying farmland water logged of rice to the Parameters of diurnal chlorophyll fluorescence kinetics in heading and flowering stage. The result shows that the initial fluorescence value Fo, the maximum fluorescence value Frn, the primary light energy conversion efficiency Fv/Fm, the potential activity of photosystem Fo/Fm, the photochemical quenching coefficient qP, non-photochemical quenching coefficient qN all along with the existence of illumination changes have a diurnal significantly variation, and there is photoinhibition at noon, and exist differences among different trends. It showsthat water logged can effect the photosynthetic mechanism of rice. A certain degree of water logged can ease the phenomenon photoinhibition of rice , even can help it ,but over water logged would damage the photosynthetic mechanism of rice. Among them, the damage of tillering stage to heading and flowering stage of three successive growth stages water logged to rice mechanism of photosynthesis is most significant, we should try to avoid such situation in agricultural production.关键词
