| 摘 要： | 以‘齐黄27’大豆为材料,研究人工气候室模拟大气CO2浓度倍增(700μmol.mol-1)的环境条件下大豆植株在生长、色素含量及光合作用相关指标的变化。结果表明:CO2倍增显著增加株高、干鲜重和根瘤数,显著降低根冠比;CO2浓度倍增处理增加了叶绿素、花青素和类胡萝卜素含量,使光合速率、Rubsico的活性、气孔导度和PSⅡ的功能都有所增加。CO2浓度倍增处理对大豆植株的生长具有促进作用,主要是由于高浓度CO2增加了根瘤的数量,增加了叶片叶绿素和类胡萝卜素含量,提高了Rubsico活性,增强了PSⅡ功能并且提高了气孔导度,最终使光合速率增加所致。

| Abstract: | The effects of doubled carbon dioxide concentration(700 μmol · moL~(-1))on some relevant indicators of growth and development,biomass accumulation and photosynthesis in soybean(Glycine max Merr.)were investigated in artificial climate room with soybean cultivar Qihuang 27 as material.Doubled CO_2 significantly increased plant height,dry weight,fresh weight and the number of root nodule while significantly decreased the root/shoot ratio; Doubled CO_2 significantly increased the contents of chlorophyII,carotenoid and anthocyanin;Doubled CO_2 increased photosynthesis rate,rubsico activity,stomatic conductance,and Fv/Fm.Results suggest doubled CO_2 enhanced photosynthesis by increasing related physiological traits,hence,promoted the growth of soybean plants. |
