Abstract
This experiment was conducted to find out the some physiological characteristics and nitrogen fixation activities under free-living conditions of indigenous rhizobia isolated from soybean-cultivated (30 fields) and un-cultivated (30 fields) soil. The results were summerized as follows: 1. In free-living condition, only 12.8% and 6.4% of the indigenous rhizobia isolated from soybean cultivated (133 strains) and un-cultivated (125 strains) soils were nitrogenase positive as more than 4 n mole
전보(前報)에 이어 우리나라 전국(全國) 60개(個) 밭 토양(土壤)에서 분리(分離)한 토착근류균(土着根瘤菌)을 대두작부형별(大豆作付型別)로 구분(區分)하여 질소고정력(窒素固定力) 및 몇가지 생리적(生理的) 특성(特性)을 비교(比較) 검토(檢討)한 결과(結果)는 다음과 같다. 1. 토착근류균(土着根瘤菌)을 대두재배지(大豆栽培地)로 부터 133개균주(個菌株), 무재배지(無栽培地)에서 125개균주(個菌株)를 분리(分離)하여 free-living 상태(狀態)에서 아세칠렌 환원력(還元力)을 측정(測定)한 결과(結果), 전자(前者)에서 12.8%, 후자(後者)에서는 6.4%로 평균(平均) 9.7%가 4n mole
