油茶炭疽病会引致油茶落果,是南方一种严重的病害。作者自1961年至1963年对病原菌的有性世代、越冬方式和侵入途径等問题进行了初步研究。 1.病原菌的无性世代:在广东,油茶炭疽病原菌无性世代的形态特征与文献报导的大致相同,叶切片观察,分生孢子盘黑色,底部稍扁平,大小92.4—204.6微米。分生孢子梗短,无色,单胞,大小9.9—18.4×3.3—5.9微米。分生孢子长椭圓形或圓筒形,直立或稍弯曲,无色,单胞,中間有1—2个透明的油点,大小9.6—19.2×3.2—5.7
Camellia anthracnose will lead to the drop of Camellia oleifera, which is a serious disease in southern China. From 1961 to 1963, the author conducted a preliminary study of the sexual generation of pathogens, the ways of overwintering and the ways of invasion. Asexual pathogens generation: in Guangdong, Camellia anthracnose asexual morphological characteristics and literature reported roughly the same leaf section observation, the conidia disk black, slightly flat bottom, the size of 92.4-204.6 microns. Conidiophores short, colorless, single cells, the size of 9.9-18.4 × 3.3-5.9 microns. Conidia oblong or cylindrical, upright or slightly curved, colorless, single cells, the middle of 1-2 transparent oil spots, the size of 9.6-19.2 × 3.2-5.7
