摘要
[Objective] To study the effects of different culture conditions on the Fusarium oxysporurn SchL f. sp. [Method] Based on species identification of the pathogenic organism of Fusarium oxysporum Schl. f. sp, effects of different cultures and different nutrients on the mycelial growth and conidial production of Fusarium oxysporum SchL f. sp were studied. [Result] The mycelial growth and conidial pro- duction of Fusarium oxysporum SchL f. sp was different under different culture con- ditions. PDA medium was the most suitable medium for the mycelial growth and had the highest conidial production; and the mycelial grew the fastest on the medium with maltose as carbon source or peptone as nitrogen source, which also had the highest conidial production. [Conclusion] This study provided experimental basis for the study of Fusarium oxysporum SchL f. sp and also provided theoretical basis for the study and control of Fusarium oxysporum Schl. f. sp.
[目的]研究不同培养条件对瓠瓜枯萎病菌的影响。[方法]在鉴定了安徽省瓠瓜枯萎病菌病原物的基础上,进一步研究了不同培养基和营养条件对该病原菌的生长速率及产孢量的影响。[结果]瓠瓜枯萎病菌在不同培养条件下的生长速率和产孢量明显不同。PDA培养基最适合该病原菌的生长,产孢量以其最高;在麦芽糖为碳源或蛋白胨为氮源的培养基上该病原菌生长最快,产孢量最高。[结论]该研究为丰富瓠瓜枯萎病菌生物学提供了实验依据,并为瓠瓜枯萎病的研究及防治提供了理论基础。
