猕猴桃溃疡病调查研究

摘要

对陕西西安(周至、户县、长安)地区12个村60个猕猴桃园的猕猴桃溃疡病发病特点调查分析，发现品种、树龄与猕猴桃溃疡病的发生直接相关，4个主栽品种(红阳、亚特、秦美和海沃德)中红阳最感病，亚特和海沃德次之，秦美发病最轻；且随着树龄的增大溃疡病危害相应加重(3~13 a 生)。地区之间猕猴桃溃疡病严重程度存在着不同程度的差异，除地区间小气候外，管理水平也是影响溃疡病发生的重要因素之一。%Through investigation and analysis on the clinical characteristics of kiwifruit Actinidia bacterial (Canker) in 60 kiwifruit Park of 12 villages, Shanxi Xi’an including Zhouzhi, Huxian and Chang’an, we found that the occurrence of canker is directly related to the varieties and tree age of kiwifruit. Hongyang is the most susceptible cultivar in four cultivars: Hongyang, Yate, Qinmei and Hayward, Yate and Hayward followed, Qinmei is best. With the increasing of tree age, kiwifruit Actinidia bacterial (Canker) would heavy. There are some differences between areas of kiwifruit Actinidia bacterial (Canker) severity, besides regional climate, management level is one of the important factors that affect the occurrence of disease.
