將內生菌根菌(Glomus mossae)與根瘤菌(Rhizobium sp.)共同或單獨接種落花生根部，均會嚴重影響其蛋白質總量、氨基酸及氮素部份的含量。本試驗探討蛋白質中氨基酸與游離氨基酸的量與質，發現共同接種內生菌根菌與根瘤菌者，其氮含量、蛋白質總量、氨基酸及glutamate dehydrogenase的累積均較單獨接種者為明顯。

The inoculation of groundnut plants with VAM fungus of Glomus mossae and Rhizobium sp. alone and also in combination greatly influenced the levels of total proteins, amino acids and nitrogen fractions. Both qualitative and quantitative changes in free and protein bound amino acids were studied. Accumulation of nitrogen fractions, total proteins, amino acids and the activity of glutamate dehydrogenase was more pronounced in the dual inoculated plants.
