接种根瘤菌和施用硝酸盐对豆科植物生物活性物质含量的影响是微生物、植物和化肥之间相互作用以及豆科植物栽培实践的一个有趣方面。在这项研究中，硝酸盐（0，5和20 mmol l-1）和花生慢生根瘤菌菌株CCBAU 051107 T，单独或组合，根际药用豆科植物苦参艾顿（SFA）。并对苦参素的植株生长、促生长作用及氧化苦参碱等有效成分进行了测定和比较。单独接种根瘤菌显著增加了根瘤的数量和鲜重。硝酸盐（5和20 mmol l−1）显著抑制结瘤。在未接种根瘤菌和未添加硝酸盐的对照植株中仅检测到氧化苦参碱，而在接种B的植株中氧化苦参碱和苦参碱均被合成。花生或提供硝酸盐。氧化苦参碱的含量在单独接种根瘤菌的植株中最高，并且不受额外施用硝酸盐的显着改变。B的组合。花生接种和不同浓度的硝酸盐处理对苦参中氧化苦参碱的含量没有显著影响。因此，单一接种根瘤菌是提高药用豆科植物SFA中关键活性成分氧化苦参碱和苦参碱含量的最佳途径。
Effect of rhizobial inoculation and nitrate application on the content of bioactive compounds in legume plants is an interesting aspect for interactions among microbes, plants and chemical fertilizers, as well as for cultivated practice of legumes. In this study, nitrate (0, 5 and 20 mmol l−1) and Bradyrhizobium arachidis strain CCBAU 051107T were applied, individually or in combination, to the root rhizosphere of the medicinal legume Sophora flavescens Aiton (SFA). Then the plant growth, nodulation and active ingredients including (oxy)matrine of SFA were determined and compared. Rhizobial inoculation alone significantly increased the numbers and fresh weight of root nodules. Nodulation was significantly inhibited due to nitrate (5 and 20 mmol l−1). Only oxymatrine was detected in the control plants without rhizobial inoculation and nitrate supplement, while both oxymatrine and matrine were synthesized in plants treated with inoculation of B. arachidis or supplied with nitrate. The content of oxymatrine was the highest in plants inoculated solely with rhizobia and was not significantly altered by additional application of nitrate. Combinations of B. arachidis inoculation and different concentrations of nitrate did not significantly change the concentrations of (oxy)matrine in the plant. In conclusion, sole rhizobial inoculation was the best approach to increase the contents of key active ingredients oxymatrine and matrine in the medicinal legume SFA.
