钼肥对酿酒葡萄光合及果实品质的影响
Effects of molybdenum fertilizer on photosynthesis and fruit quality in wine grapes
摘要
Abstract
Taking the wine grape variety Marselan as test material,this study investigated the effects of foliar application of two molybdenum fertilizers(sodium molybdate and ammonium molybdate)at five concentrations(0.1 μM,1 μM,5 μM,10 μM,and 100 μM)on photosynthesis and fruit quality.The results showed that compared with the control,foliar application of sodium molybdate and ammonium molybdate at different concentrations significantly increased leaf chlorophyll content,net photosynthetic rate,intercellular CO₂ concentration,stomatal conductance,transpiration rate,water use efficiency,and the maximum photochemical efficiency of chlorophyll fluorescence,with the 1 μM treatment showing the most pronounced effects.Meanwhile,the 1 μM molybdenum treatment also improved the fruit quality of wine grapes,including single berry weight,soluble solids,total phenol,and anthocyanin contents,while titratable acidity decreased.关键词
