Abstract

Small-seeded legumes can be cultured enclosed in slant agar tubes if dlese plants are to he used for authenicaiing rhizobia or for enumerating 1-hizobia by the plant-inlection technique. An improved method has been developed with substiluting agar slant lor Korean paper(Har7ji). This method was panicularly useful for legumes with rigid radicle such as Cn.xsin 1mnmame. With this method Bmr!,~li1rzobin,17 sp. stram CN9135 on C nonmne induced root nodules biginning at day 7 of the nodulation period in 6% of the l ~ l a ~ l s , and all of ihe plants nodulated 14 days after inoculation by strain CN9135.

한천 사면배지 대신 한지를 사용하여 시험관내 뿌리혹생성 실험방법을 개선하였다. 개선된 이 방법은 기존의 한천-시험관 법에 비해 전체 과정이 간단하며, 특히 굵고 단단한 유근을 갖는 콩과식물에서도 효과적으로 사용할 수 있다. 이 방법을 사용하여 Bradyrhizobium sp. CN9135을 접종한 차풀에서 접종후 7일째부터 조사된 식물개체의 6%에서 뿌리혹이 생기기 시작하여 14일 째에 조사된 모든 식물개체에서 뿌리혹이 생성되었다.
