氟铝互作对茶树叶片叶绿素荧光特性的影响
Effect of Fluoride and Aluminum Interaction on the Chlorophyll Fluorescence Characteristics of Tea Leaves
摘要
Abstract
To study the effect of fluoride and aluminum intertreatment on the chlorophyll fluorescence characteristics of tea leaves, different concentrations of fluorine and aluminum were used and the fluorescence parameters were analyzed by modulated chlorophyll fluorescent instrument. The results found that: the actual photosynthetic efficiency Y(Ⅱ), the maximum (Fm), primary maximum photochemical efficiency of PSⅡsuch as Fv/Fm and coefficient of photochemical quenching such as qP and qL of tea seedlings decreased with the increase of fluorine concentration without aluminum. But the non-photochemical quenching coefficients (NPQ), Fo, non-photochemical quenching coefficient (NPQ and qN) and PSII regulated energy dissipation increased. At low aluminium levels, Fm, Fv/Fm, Y(Ⅱ), NPQ and qN decreased with the increase of fluorine concentration, while qP and qL increased. There were no significant differences between the Fo, Y(NO) and Y(NPQ) values at this time. Under high aluminium treatment, with the increase of fluorine treatment concentration, the Fo gradually increased, Y(Ⅱ), Fv/Fm, qP decreased, Y(NPQ) and NPQ increased significantly under low fluorine concentration (100 mg·L-1). In short, for tea trees under fluorine stress, aluminum could reduce the damage to tea plants, especially under low aluminum level. The improving effects of photosynthetic efficiency were more obvious.关键词
