在果树病害的病原菌中,葡萄座腔菌是为害性极广的病原菌。几乎为害所有果树, 本菌属小壳子囊菌类,繁殖器官是黑色子座组织中的子囊孢子和分生孢子。各壳室内的子囊孢子和分生孢子在天气潮湿时放出。重复着侵染——发病——形成繁殖器官——放出孢子的寄生生活。繁殖器官在病患部表皮下形成,成熟后即露出黑色子座的顶部,薄薄的切开黑色子座,肉眼可见一至数个球形肺室,腔室初期为炭质,成熟后呈乳白色,在显微镜下观察白 In the pathogen of fruit tree disease, the bacteria is very harmful pathogenic bacteria. Almost all harmful fruit trees, the genus is a small ascomycetes, reproductive organs of the black asteroid tissue ascospores and conidia. Ascospores and conidia in each shell chamber are released when the weather is wet. Repeated infection - onset - the formation of reproductive organs - spore parasitic parasitic life. The reproductive organs are formed under the epidermis of the patient’s part. After maturation, the top of the black child seat is exposed, and the black child seat is thinly cut out. One to several spherical lung chambers are visible to the naked eye. The cavities are initially charcoal in maturity, Observed under a microscope white
