Were studied together with the reference strains of recognized rhizobium and bradyrhizobiwn species by performing polyphasic taxonomy, including numerical taxonomy, rep - pcr fingerprinting, 16s rdna pcr - rflp. the result show that : the growth rate of rhizobia isolated from the root nodules of pueraria spp. showed great diversity. ccbau41147 ccbau6110 k ccbau61096 and ccbau61095 were fast - growing strains, the single colony size was bigger than 1mm after 2 days incubated oq yma medium at 28 they can produce acid. the other strains were slow - growing strains, their single colony size was less than 1 mm after 7 days incubated on yma medium at 28. they can produce alkali
本研究以從我國四川、河南、安徽和湖南等地分離的32株葛藤根瘤菌為研究對象，以20株已知種的根瘤菌為參比菌株，採用數值分類、 rep - pcr指紋分析、 16srdnapcr - rflp指紋分析等現代根瘤菌分類技術，初步研究了葛藤根瘤菌的生物多樣性和分類地位，結果表明：葛藤根瘤菌在生長速率上表現出多樣性，菌株ccbau41147 、 ccbau61096 、 ccbau61101和ccbau61095生長較快， yma培養基上28培養2 - 3天後，單個菌落直徑大於1mm ，具有產酸能力，是快生型葛藤根瘤菌；其餘待測葛藤根瘤菌生長較慢， yma培養基上28培養7天後，單個菌落直徑小於1mm ，具有產堿能力，是慢生型葛藤根瘤菌。 -
