摘要
根据Nelson,Toussoun&Marasas(1983)的分类系统,选取在PDA和CLA培养基上的50个编码性状,利用系统聚类分析的平均连锁法,初步建立了30种镰刀菌属(Fusarium)真菌为基础的计算机鉴定系统。用这个系统对玉米穗粒腐病上的三个未知菌株(Fusarium sp.1,F.sp.2,F.sp.3)进行鉴定的结果表明,F.sp.1为F.graminearum,F.sp.2为F.moniliforme,F.sp.3为F.proliferatum或F.subglutinans。从而证明此鉴定系统具备比较、鉴定性能。
Based on the taxonomic system of Nelson et al. (1993) ,a preliminary computerized identification system with groupaverage method of hierachical cluster analysis for the genus Fusarium was established. Three unidentified isolates, Fusarium sp. 1 F. sp. 2 and F. sp. 3 from Zea mays L. , were identified by use of this analysis. The results clearly showed that F. sp. 1 was identified as F. graminearum, F. sp. 2 as F. moniliforme and F. sp. 3 as F. subflutinans or F. proliferatum. The facts proved its applicability to comparison and identification of Fusarium.
