Phenotypic diversity of rhizobia isolated from bayi town in linzht area 林芝地區(qū)八一鎮(zhèn)根瘤菌的表型多樣性研究
An experiment was conducted to analyse the phenotypic diversities between and within populations in terms of ten phenotypic traits using ten populations of wintersweet from the whole distribution areas in china as experimental materials 摘要以蠟梅全分布區(qū)的10個(gè)群體為試材,對(duì)10個(gè)表型性狀進(jìn)行比較分析,討論群體間和群體內(nèi)的表型多樣性。
The result of numerical taxonomy indicated that there were high phenotypic diversity among the strains isolated from the root nodules of pueraria spp . it can been seen in utilization of carbon and nitrogen sources , antibiotic resistance , resistance to dyes and chemicals , tolerance to acid , acid production , alkali production , nitrate reduction et al . the dendrogram divided all the strains into 數(shù)值分類對(duì)所有供試菌株進(jìn)行了131項(xiàng)表型性狀的測(cè)定,結(jié)果表明,葛藤根瘤菌具有豐富的表型多樣性,表現(xiàn)在利用多種化合物作為唯一碳源、氮源能力,對(duì)抗生素、染料和化學(xué)藥物的抗性,耐酸性,產(chǎn)酸產(chǎn)堿情況,硝酸還原能力等方面。
