【摘要】 【目的】明确基因型、环境以及基因型与环境互作(G×E互作)对大麦籽粒酚酸含量的影响。【方法】以7个大麦品种为材料,种植在3个生态条件迥异的地区,测定其籽粒酚酸含量,并采用主效可加互作可乘模型进行分析。【结果】基因型、环境以及G×E互作对所分析的各酚酸指标的影响均达到极显著水平。对于原儿茶酸和丁香酸含量,G×E互作的影响最大,其次为环境型,基因型的影响最小;对于香草酸含量,G×E互作的影响最大,其次为基因型,环境的影响最小;对羟基苯甲酸、总羟基苯甲酸衍生物和总酚酸含量,环境效应的影响最大,其次为G×E互作,基因型的影响最小;对于阿魏酸和总羟基苯甲酸衍生物含量,基因型效应的影响最大,其次为G×E互作,环境的影响最小。【结论】基因型、环境以及G×E互作对大麦籽粒中主要酚酸成分含量有着极显著的影响。更多还原

【Abstract】 【Objective】The study was to reveal the effects of genotype(G) and environment(E) as well as their interactions(G×E) on the contents of phenolic acids in barley grain.【Method】 Seven barley varieties were selected and cultivated in 3 locations with different ecological conditions.The contents of phenolic acids in barley grain were detected and analyzed by using additive main effects and multiplicative interaction model.【Result】 The results indicated that all the phenolic acid indexes analyzed were significantly(P<0.01) influenced by G,E and G×E.For the contents of protocatechuic acid and syringic acid,the effect of G×E was most significant,followed by E and G;For the content of vanillic acid,the effect of G×E was still most significant,however,followed by G and E;For the contents of p-hydroxybenzoic acid,total hydroxybenzoic acids and total phenolic acids,the effect of E was most significant,followed by G×E and G;For the contents of ferulic acid and total hydroxycinnamic acids,the effect of G was most significant,followed by G×E and E.【Conclusion】 Primary phenolic acids in barley grain were all significantly influenced by G,E and G×E.更多还原
