摘要
为了探讨不同浓度外源酚酸对分枝期大豆生长发育的影响,采用盆栽试验的方法,对盆栽大豆生长发育几种指标进行了研究。结果表明:除香草酸外,苯甲酸和肉桂酸处理均显著抑制了分枝期大豆株高的生长。3种酚酸处理均显著抑制了分枝期大豆叶面积的增加。酚酸浓度为0.01 g/kg时,3种酚酸处理促进分枝期大豆根瘤数的增加;当酚酸浓度大于或等于0.1 g/kg时,3种酚酸处理对大豆根瘤数增加的抑制作用逐渐增强。3种酚酸处理对分枝期盆栽大豆根冠比影响不同,但是均与对照差异不显著。
In order to explore the effects of different concentrations of exogenous phenolic acids on branchingsoybean growth and development,the several indicators were studied on potted soybean by the approach of potexperiment.The results showed that,benzoic and cinnamic acid treatment significantly inhibited the growthand branching of the soybean plant height except vanilla acid treatment.Three acid treatments significantlyinhibited the increase in branching soybean leaf area.When the acid concentration was 0.01 g/kg,three kindsof acid treatment increased the number of branches of soybean root nodules.When the acid concentration wasgreater than or equal to 0.1 g/kg,three acid treatments of soybean nodule number increased inhibitiongradually.The influence of three kinds of acid treatment on the shoot ratio of potted branching soybean wasdifferent,but the difference was not significant with the control.
