摘要
明确番茄枯萎病苗期抗病性鉴定方法中浸根接种的最佳苗龄为两片真叶期，此龄期根系发育多，拔苗后须根自然伤断，浸根接种率高。浸根接种随即移栽的与浸根２、５、１０ｍｉｎ的，它们之间发病差异不大。包括接种液浓度１０７孢子／ｍｌ和土温２８℃～３０℃在内的苗期人工接种方法。
The results of this study indicated that the optimal stage of tomato seedling inoculated by root dipping for resistance identification to Fusarum oxysporum is at 2 true leaf stage, when the fibrous roots are numerous and liable to be hurt. Thus resulted in high inoculation rate by root dipping. The occurrence of Fusarium wilt showed no significant difference when inoculated plants were re planted at once or at 2, 5, 10 minutes after dipping. With an inoculum concentration of 10 spores per milliliter and at 28℃～30℃ in a greenhouse,resistance of tomato varieties to Fusarium oxysporum can be determined and screened accurately.
