摘　　要：抽样调查了湘西州吉首等6个县(市)12村14个果园7个猕猴桃品种的溃疡病发病情况及其影响因素,结果表明:湘西州猕猴桃果园的发病率占调查果园总数的85.7%,且猕猴桃溃疡病的发病率和病情指数与栽培品种、海拔高度、果园管理水平等因素有关;7个品种中,红阳猕猴桃为高感品种,翠玉为高抗品种;果园的海拔高度与溃疡病发病率呈显著正相关,海拔越高同一品种发病越重;果园的管理水平越低溃疡病发病越重;并针对湘西州的猕猴桃溃疡病发病情况提出了5点防治建议。Bacterial canker disease is a devastating disease and the greatest limiting factor in kiwifruit cultivation.In this paper,the occurance of bacterial canker and its influencing factors were investigated and analyzed in random samples of seven kiwifruit cultivars in 14 orchards located in 12 villages of six counties of Xiangxi Prefecture,Hunan Province.The results showed that this disease was severity in these orchards with an incidence rate of 85.7%.Moreover,the incidence rate and incidence index of kiwifruit canker was closely related to such factors as cultivar,altitude and orchard management level.Of all the seven cultivars,‘Hongyang’ was a highly susceptible variety and ‘Cuiyu’ was a highly resistant variety.There was a significant positive correlation between the altitude of orchards and the incidence of bacterial canker.For the same variety,the higher the altitude of the orchard was located in,the severer the disease occurrence was.Furthermore,we found poorer orchard management led to severer canker incidence.So,we put forward five suggesions for the control of kiwifruit canker in Xiangxi region.
