研究了菌根真菌（Glomus fasciculatum、Glomus mosseae）生物肥料及其与固氮菌（Azotobacter chroococcum）、增钾菌（Bacillus mucilaginous）和增磷菌（Bacillus megaterium）的复合施用对土壤肥力和菠菜化学成分的影响。与单独接种处理相比，在细菌接种的存在下，菌根真菌的根定殖增加。接种含菌根真菌和细菌的生物肥料显著提高了总酚、黄酮和酚酸的含量。菠菜对DPPH自由基的清除能力与总黄酮含量呈正相关，与总酚和酚酸含量部分相关。此外，高效液相色谱分析表明，显着较高的抗氧化活性菠菜的槲皮素和绿原酸的含量。叶绿素含量也随着生物施肥处理的进行而增加。结果表明，这些微生物是改善菠菜中健康促进化合物的有用工具。
This study evaluates the influences of bio fertilizers containing mycorrhizal fungi (Glomus fasciculatum, Glomus mosseae) individually or in combination with N-fixer (Azotobacter chroococcum), K solubilizer (Bacillus mucilaginous) and P solubilizer (Bacillus megaterium) on soil fertility and phytochemical levels of spinach. Root colonization by mycorrhizal fungi was increased in the presence of bacterial inoculation in comparison to individual inoculation treatments. Inoculation of bio fertilizer containing mycorrhizal fungi and bacterial species considerably augmented the concentration of total phenolic compounds, flavonoids and phenolic acid contents. The 1, 1-diphenyl-2-picrylhydrazyl (DPPH) scavenging capacity of spinach was found to be positively coincided with flavonoid contents, while partially correlated with total phenolic compounds and phenolic acids. Further, the HPLC analysis showed that significantly higher antioxidant activity of spinach was correlated with quercetin contents and chlorogenic acid. Chlorophyll contents were also increased following the bio fertilization treatments. Results revealed that these microbes are useful tool for improving health promoting compounds in spinach.
