摘    要:为明确豫西地区茄科作物土壤镰孢菌菌株间的系统发育关系,对从豫西地区17 个县、市
采集的32 份土壤样品中分离得到的96 株镰孢菌进行形态学鉴定及EF-1α 序列分析。结果表明:供试
镰孢菌分属于5 个种,位于系统发育树的5 个分支上,分别为尖孢镰孢菌(F. oxysporum)、藤仓镰孢菌
(F. fujikuroi)、轮枝镰孢菌(F. verticillioide)、F. incarnatum 和F. incarnatum-equiseti species complex。
其中尖孢镰孢菌(F.oxysporum)的分离频率最高,为45.83%,在所调查的4 种茄科作物土壤中均有分布;
而F.incarnatum-equiseti species complex 的分离频率最低,仅在马铃薯和番茄土壤中存在。不同地区茄科
作物土壤镰孢菌种群存在差异。

关 键 词:茄科作物  镰孢菌  EF-1&alpha  种群多样性

Abstract:Morphological observation and sequence analysis of EF-1α of tested Fusarium strains
collected from the Solanaceae crops soil in western Henan Province were carried out to clarify the species
diversity and phylogenetic relationships among Fusarium strains.The results showed that 5 branches
of Fusarium were identified in the phylogenetic tree,namely F. oxysporum,F. fujikuroi,F. verticillioide,
F. incarnatum and F.incarnatum-equiseti species complex. Among them,F. oxysporum had the
highest separation frequency of 45.83%,and was distributed in all investigated 4 kinds of Solanaceae
crops soil.While,the separation frequency of F.incarnatum-equiseti species complex was the lowest,
it only existed in potato and tomato soils.In addition,species diversity existed in Fusarium strains
from different regions and different Solanaceae crops soil.
Keywords:Solanaceae crops  Fusarium  EF-1α  Species diversity
