为了给崇阳县梨树轮纹病的防治及梨果实采后储藏提供理论依据,对该地区梨轮纹病病菌进行了分离、纯化培养,采用生物学、分子学鉴定及致病力测定等方法对其进行了研究。结果表明,不同地区同一品种,同一地区同一品种,同一地区不同果树种类上分离得到的轮纹病病原菌的生长速率、致病性都存在差异。因此,在不同地区应选择适合当地环境并具有较强抗性的品种进行栽培种植;受轮纹病侵染的不同种果树不要混种,以免造成相互侵染。
In order to provide a theoretical basis for prevention and treatment of pear rotifers and postharvest storage of pear fruits in Chongyang County, the pathogen of pear ring blight in the area was isolated, purified and cultured. The methods of biology, molecular identification and pathogenicity determination Method to study it. The results showed that the growth rate and pathogenicity of pathogen isolated from different species of the same species in the same region, the same species in the same region, different fruit trees in the same region were different. Therefore, in different regions should choose suitable for the local environment and have strong resistance varieties for cultivation and cultivation; different varieties of fruit trees infected by the ring disease do not mix, so as not to cause mutual infection.
