腐皮镰孢油桐专化型(以下简称Fsa)是1985年2月30日从万县国家乡油桐病区病株中分离出的一种病原菌。经接种和回接试验结果证明,此菌是引起油桐根腐病的主要病原菌。定名腐皮镰孢油桐专化型(Fusarium Soloani(Mart)Sacc f.sp Aleurites chen et Xiao)。此菌对幼,成年桐树均能为害,特别对10—20年生树为害最重。受害的植株初期地上部份叶片变小,出现失水症状,地下部份须根腐烂逐渐蔓延到侧根,最后导致整株枯萎死亡。 本文报道Fsa菌株的形态特征及生物学特性,供参考。
Fusarium venenatum tung specialization type (hereinafter referred to Fsa) is February 30, 1985 from Wanxian country Township Tung wood disease isolates from a pathogen. After inoculation and back connection test results show that this bacteria is caused by the root rot of the main pathogen. The name Fusarium Soloani (Mart) Sacc f. Sp Aleurites chen et Xiao). This fungus on young, adult Tung can damage, especially 10-20 year-old tree damage most. Injured plants in the early part of the leaves become smaller, the symptoms of dehydration, the underground part of the root rot gradually spread to the lateral roots, and finally led to the whole plant wilt death. This article reports Fsa strain morphological characteristics and biological characteristics for reference.
