| 摘 要： | 观察了５个抗青枯病水平不同的番茄品种（品系）的愈伤组织对青枯菌平板培养滤液及活菌体的反应．结果表明，抗病材料愈伤组织较为敏感，处理后较早出现褐变、崩溃等较重的受害症状，感病材料的症状出现较慢、较轻；番茄愈伤组织的离体抗性与田间抗性呈相反趋势．

| Abstract: | The responses of calli derived from five tomato genotypes to the bacterial suspensions and the platecultural filtrates of Pseudomonas solanacearum were studied. The calli from resistant genotypes were sensitive,which browned rapidly and collapsed heavily, in comparision with that from susceptible ones. The invitro resistances showed a tendency to be contrary to the resistances infield. |
