在1984年的生长季节，对156个桃品种和40个油桃品种、49个引种品种和33个李种或杂交种进行了细菌性斑疹病的易感性评价。pruni (Smith 1903) Dye 1978)在北卡罗来纳州和南卡罗来纳州。北卡罗莱纳州的果实和叶片侵染率和落叶率被评估，而南卡罗莱纳州仅评估叶片侵染数据。各品种均无免疫力，但对其的敏感性差异较大。根据两个地点的叶片侵染情况，得出北卡罗莱纳州的病害压力较大的结论。北卡罗莱纳州果实侵染程度与叶片侵染程度和落叶率的相关系数分别为r = 0.30 （P = 0.01）和r = 0.54 （P < 0.01）。北卡罗莱纳州和南卡罗来纳州叶片侵染严重程度与落叶率的相关系数分别为r = 0.51 （P < 0.01）和r = 0.00 （NS）。
During the 1984 growing season, 156 peach and 40 nectarine cultivars, 49 plant introductions, and 33 Prunus species or species hybrids were evaluated for susceptibility to bacterial spot [Xanthomonas campestris pv. pruni (Smith 1903) Dye 1978] in North Carolina and South Carolina. Fruit and leaf infection and percentage of defoliation were evaluated in North Carolina, while only leaf infection data were evaluated in South Carolina. No cultivar was immune, but susceptibility varied greatly. Based on leaf infection in the 2 locations, it was concluded that disease pressure was greater in North Carolina. Correlation of fruit infection severity with leaf infection severity and percentage of defoliation in North Carolina was r = 0.30 (P = 0.01) and r = 0.54 (P < 0.01), respectively. Correlation between leaf infection severity and percent defoliation was r = 0.51 (P < 0.01) and r = 0.00 (NS) in North and South Carolina, respectively.
