【摘要】 对冬瓜枯萎病菌与节瓜枯萎病菌在接种浓度、接种方法等方面进行了研究。结果表明:枯萎病病菌、FOC(theculturefiltratesofFusariumoxysporum)、FA(Fusaricacid)、标准镰刀菌酸均可用于鉴定抗性;病菌适宜的接种浓度为5×106个孢子/mL;FOC接种浓度以原液的2～4倍稀释液为宜,接种时间为播种后15～20d,即1～2片真叶时期,FA的鉴定浓度以150mg/L效果最佳。更多还原

【Abstract】 The inoculation concentration and method were studied in Fusarium oxysporum Schlfsp The results indicated that the fungi,the culture filtrales of Fusarium Oxysporum (FOC) and Fusaric acid(FA) were used to identify resistance of varities It was appropriate for identification of disease resistance with soaking roots in the spore suspension, 5×106 spores/mL could be preferable, and it was suggested that the proper time for vaccination was in 15～20 days after seeding The preferable concentration of FOC was 2~4 times dilution,that of FA was 150 mg/L更多还原
