中文摘要 | 對甘肅白龍江流域甘南、隴南的大部分地區豆科植植物-根瘤菌資源進行了調查,共採集21屬45種豆科植物69份根瘤樣品。從69份樣品中獲63株根瘤菌,對其中44株根瘤以13種寄主進行了回接試驗,31株結瘤,結瘤率70.5%。該區根瘤一般帶有粉紅色,形態比較規則。乙快還原活力測定結果表明,88.5%為有效根瘤。不同種根瘤固氮活性相差不大,但高於甘肅其他地區。 |
英文摘要 | The total numbers of 69 root nodules which we have collected dispersed over 21 genera, 45 species of legumes according to our investigation of rhizobium resources of leguminous plant in Bailong river basin, Gansu, 63 strains of root nodule bacteria from 69 samples have been isolated. Experiments on 44 stains among 31 have been inoculated back to 13 species hosts. The shapes of nodules of these plants were cicular, ellipse or cudgel with pink in color. The results of acetylene reduction detection showed that 88.5% were effective for nitrogen fixation. Activities of nitrogen fixation in nodules varied littlely and were higher than these in other areas of Gansu. |
