Soil and leaf analyses were used to survey magnesium status of different soils and crops in different governorates of Egypt during the period from 1986 - 2006. Results show that large areas in differe...
玉米根围土壤中腐霉菌的分离鉴定及核糖体DNA－ITS犐犜犛序列分析
玉米 根围土壤 腐霉 鉴定 核糖体ＤＮＡ－ＩＴＳ
2009/11/17
从兰州地区的红古、七里河等地采集玉米根围土壤标样，诱饵法与组织分离法相结合分离纯化到２３株腐霉菌株，通过形态特征、培养特性、生长速度和对温度适应范围的研究，结合ｒＤＮＡ－ＩＴＳ序列分析，将分离到的腐霉菌株鉴定为硬腐霉、终极腐霉和一个腐霉待定种。这是首次报道在我国分离到硬腐霉，为我国新记录种；终极腐霉也系首次在甘肃从玉米根围土壤中分离到。统计表明，３种腐霉菌种在兰州地区玉米根围土壤中的分离频率不同，...
