| 摘 要： | 为了筛选对胡麻枯萎病有较好抗性的放线菌,试验对胡麻根围土壤进行了筛选,最终得到1株对胡麻枯萎病病原菌尖孢镰刀菌有较强拮抗作用的放线菌GS2-1.分别测定了它对不同地区分离得到的151株尖孢镰刀菌的抗性,发酵液对孢子和菌丝的抑制作用,研究了其最佳发酵条件,并对发酵液中的抑菌活性物质进行了初步提取和生物活性测定,最后对其在... |

| Abstract: | In order to get a antagonistic actinomycete against linseed wilt,an actinomycete GS2-1 was isolated from pathogenic soil of linseed,which could inhibit growth of Fusarium oxysporum f.sp.lini.The inhibition rates against 151 fungi isolated from different provinces were evaluated.The fermentation filtrate influencing the mycelium growth and the spore bourgeoning and the optimum fermentation conditions were also conducted.Antagonistic substance was extracted from the fermentation liquid,its activity in lab and... |
