前言烟草对黑胫病(Phytophthoraparasitica var.nicotianae)的抗性的鉴定方法,大致分为大田病圃自然鉴定与人工接种鉴定,目前日本几乎都采用人工接种鉴定法。人工接种鉴定有根部接种法(Apple,Trout-man 等,Litton 等)和叶片接种法(鱼住,Wills 和 Crews,Wills,大部),现在在抗性鉴定和选择上广泛利用的是Apple 的铝盘鉴定法(大桥、金泽)。但是人工接种鉴定比自然鉴定的结果常有发病过高的趋势,有时观察到抗病品种感病过重。其原因是受
Foreword Tobacco on the black shank disease (Phytophthoraparasitica var. Nicotianae) resistance identification methods are generally divided into Daejeon nursery natural identification and artificial inoculation identification, almost all currently used in Japan artificial inoculation method. Artificial inoculation assays include the root inoculation method (Apple, Trout-man et al., Litton et al.) And the leaf inoculation method (Fusarium, Wills and Crews, Wills, Most) and now the most widely used for resistance identification and selection is Apple Aluminum plate identification method (Bridge, Kanazawa). However, the artificial inoculation identification is often over-established compared with the natural identification results, and sometimes it is observed that the resistant varieties are over-susceptible. The reason is affected
