【摘要】 香料烟细菌性斑点病是一种由丁香假单胞菌烟草致病变种[Pseudomonas syringae pv.tabaci(Wolfet al.)Young et al.]侵染引起的新病害,是香料烟生产中的主要病害。采用自然病圃结合人工接种的方法对香料烟品种的细菌性斑点病进行了抗性鉴定研究。结果表明不同品种发病动态差异明显,’基可纳巴斯玛’、’巴斯玛14号’、’罗香1号’、’沙姆逊’发病较早,发病后病情稳定,未发现扩展趋势,香料烟多叶发病晚,发病后病情加重迅速。接种后21天调查,’伊兹密尔14号’、’科库鲁·伊兹密尔’、’土卡单株3’、’罗明2-1’、’香料烟多叶’叶片全部枯竭,剩余23个品种有6个中感、10个中抗和7个高抗品种,分别占26.09%、43.48%和30.43%。高抗品种包括’巴斯玛1号’、’卡拉巴格拉’、’杰尼克’、’罗香1号’、’沙姆逊’’、巴斯玛14号’’、基可纳巴斯玛’。更多还原

【Abstract】 Oriental tobacco bacterial leaf spot disease is a new bacterial disease infected by Pseudomonas syringae pv. tabaci (Wolf et al. ) Young et al. and is the main disease of oriental tobacco. The oriental tobacco varieties were identified for their resistance to bacterial leaf spot disease, with the method of natural disease plot and manual inoculation. The results indicated that the incidence trends of different variety differed obviously. The variety‘Base kona Basma’、‘Basma No. 14’,‘Luoxiang No. 1’,‘Sam sum’pathogenesis time was ealier, and the plant’s condition did not turn worsen, the variety multi-leaf oriental tobacco was later and the plant’s condition was expanding speedly. At 21 days after inoculation, the leaf was dried up of variety ‘Izmir NO. 14’,‘Kokulu·|zmir’,‘Turker Tuka-3’‘( Turker Basma’בCarabaglar’),‘Luoming No. 2-1’, multi-leaf oriental tobacco. Of all the other 23 varieties, there were mid-susceptible, 43.48% mid-resistant and 30.43% high-resistant.‘Variety Basma No. 1’,‘Carabaglar’,‘Canik’,‘Luoxiang No.a’,‘Sam sum’, ‘Basma No. 14’and‘Base kona Basma’was high resistant to bacterial leaf spot disease.更多还原
