【摘要】 对7个番茄品种和2个对照材料接种青枯病菌后用印迹法检验,并与常规田间抗病性鉴定法进行比较,结果表明植株在距离根茎部向上25cm处青枯病菌的检出率高、低与田间植株的感、抗性基本对应,据此认为在不利于青枯病发生的低温季节,印迹法可用于抗病性鉴定。更多还原

【Abstract】 The resistance to bacterial wilt caused by Ralstonia solanacearum in 7 tomato cultivars and two controlls was evaluated by a sstem seal method. The results tended to be similar with that obtained by the conventional evaluation method, with low stem colonization at 25cm above the base corresponing to high resistance. It suggested that the stem imprint method could be used in resistance evaluation, especially in cool seasons.更多还原
