极细链格孢激活蛋白对大豆光合特性、叶绿素荧光参数及产量的影响
Effect of Activator Protein from Alternaria tenuissima on Characteristics of Photosynthesis, Chlorophyll Fluorescence Parameters and Yield of Soybean
摘要
Abstract
To investigate the influence of activator protein on the growth of soybean,the characteristics of photosynthesis,chlorophyll fluorescence parameters and yield of soybean variety Jidou 17 at different concentrations (1,2,3,4,5,6 μg/mL) of activator protein from Alternaria tenuissima were investigated using photosynthesis system and weighing method.The results showed that with increased concentrations of activator protein,chlorophyll content,net photosynthetic rate,stomatal conductance and transpiration rate,optimal photochemical efficiency of PS Ⅱ (Fv/Fm),effective quantum yield of PS Ⅱ (φpsⅡ) and photochemical quenching (qP) in soybean increased first and then decreased.After spraying 1,2,3,4 μg/mL concentrations of activator protein,soybean not only improved leaf chlorophyll content,but also increased the net photosynthetic rate,stomatal conductance and transpiration rate,while increasing the optimal photochemical efficiency of PS Ⅱ (Fv/Fm),effective quantum yield of PS Ⅱ (φPSⅡ) and photochemical quenching (qP).The effect of 3,4 μg/mL activator protein was of best efficiency to the plant.However,a further increase in activator protein to 5,6 μg/mL reduced above these improving effects.The soybean yield increased by 11.21％-14.76％ after using 3,4 μg/mL activator protein.These results indicate that spraying proper concentration activator protein from Alternaria tenuissima is an effective measure to promote soybean yield.关键词
