| 摘 要： | 镰刀菌酸是棉花枯萎病菌的次生代谢产物,对一种非特异性的毒素。为了探索棉花枯萎病原菌的镰刀菌酸产量与致病力的关系及不同棉花品种对镰刀菌酸的反应,本实验测定了10个新疆吐鲁番地区的菌株和20个内地的菌株,发现其产镰刀菌酸的数量多少与生理型无关.培养初期各菌株的镰刀菌酸产量与菌株的致病力有关.陆地棉的10个品种对镰刀菌酸的抗性与它们在生产中表现出对枯萎病的抗性一致.

| Abstract: | Ten strains of Fusarium oxysporum f.sp.vasinfectum collected from Xinjiang and twenty strains collected from other provinces have been studied.There were no clear relationship between the production of fusaric acid and the physiological types.For the purpose to know the relation between virulence and the production of fusaric acid in modified Richard's medium,the culture was incubated at 25-26℃ on a rotating shaker.The resistance of ten varieties of G.hirsutum L.to fusaric acid was correlated with their resistance to cotton wilt disease. |
