摘要
蓝莓（Vaccinium spp．）属于杜鹃花科（Ericaceae）越橘属（Vaccinium）多年生小浆果类果树，广泛应用于医药、保健、化妆品和环境保护等领域，联合国粮农组织将其果实列为世界五大健康食品之一。我国已有10多个省份开始大面积的蓝莓商业化栽培，这也是南方酸性土丘陵地区值得发展的经济作物。随着栽培面积的不断扩大，蓝莓病害日趋突出，严重影响和制约蓝莓产业的发展。然而，我国对蓝莓的病害研究有限。蓝莓叶斑病是近年来在我国云南地区发生的一种新病害。
A new leaf spot disease of Highbush Blueberries （Vaccinium corymbosum L. ） was found in Yunnan, China. Typical symptoms of the disease were circular to irregular, light brown-to-gray leaf spots with brownish red borders, initially 2 to 3 mm in diameter, enlarged and coalesced. All of isolates were isolated from leaf spot diseased samples of infected blueberry plants. Based on the the result of pathogenicity testing, it was proved that LANMEI036 isolate was the pathogen of Highbush Blueberries leaf spot. The LANMEI036 isolate was identified as Alternaria tenu＆sima based internal transcribed spacer region （ ITS1-5.8S-ITS2 ）. deposited in GenBank （ Accession No. KF791343 ）. Highbush Blueberries leaf spot disease in China. on morphological characters and sequence of rDNA Representative sequence of LANMEI036 isolate was A. tenuissima was first reported as the pathogen of
