摘要
可可毛色二孢菌(Lasiodiplodia theobromae Pat. Griffon & Maubl.)属葡萄座腔菌属(Botryosphaeria)病原菌的无性型,其有性型为Botryosphaeria rhodina(Berk. & M.A. Curtis)Arx[1,2]。该病原菌可导致热带、亚热带地区的植物发生病害,如葡萄树干溃疡和顶梢枯死[3],春芋叶斑病[4],橄榄溃疡病[5]等。叶斑病是茶树的一类重要病害。
The tea leaf disease, which led to a large loss of production and decrease of quality, was found in the tea region in Huishui county, Guizhou province. Some strains were isolated from the diseased samples, and the representative strains fulfilled Koch’s postulate. Then the isolates were further identified as Lasiodiplodia theobromae based on morphological characters and phylogenetic analysis with internal transcribed spacer(ITS) and elongation factor 1-α(EF-1α) regions. The results showed that the pathogen of the leaf disease occurred in Huishui county, Guizhou province was L. theobromae.
