摩西球内囊霉和慢生根瘤菌单独或者共同接种两个不同品种的豇豆栽培种，结果表明根瘤数和豇豆生长在很大程度上受接种物的影响．当感染率由２．６７％提高至１０．６％时，豇豆地上植株平均干物重由０．３７克／株增至０．６６克／株，同时也发现寄主植物和共生菌的关系在同一种的不同植株上呈不同表现 Two species of cowpea cultivars were inoculated separately or co-inoculated with N. griseus and B. brasiliensis. The results showed that the number of nodules and the growth of cowpea were largely affected by the inoculum. When the infection rate increased from 2.67% to 10.6%, the average dry weight of the above-ground cowpea plant increased from 0.37g / plant to 0.66g / plant, and the relationship between the host plant and symbiont was also found to be the same Different kinds of plants showed different performance
