摘要: 利用不同方法对67个欧亚种葡萄品种种白粉病感病性的鉴定结果表明,不同品种之间人工离体叶圆片接种的感病水平的变异范围大于果实自然发病率,能更为准确、充分地反映品种之间抗病性的微小差异;同时,在人工离体叶圆片接种中,白粉菌子孢子直接接种效果优于悬浮液接种;通过接种试验还确定了在本试验试验条件下的最佳接种浓度。

Abstract: The several methods were adopted to identify susceptibility of 67 cultivars of V. uinifera to U. necator. The tesults showed that that the varying range of susceptibal level of the cultivats using artificial inoculation of isolated circular-leaves was much greater than that of fruits natural incidence of the disease in field, and could reflect tiny difference of susceptibility among the cultivars more accurately. Moreover, effect by using dry conidia inoculation was superior to that by using suspension inoculation between the two kinds of artificial inoculation at the isolated cirular-leaves in laboratory. The most suitable extent of inoculation under this condition was determined by testing.
