Abstract

Typical anthracnose symptoms were observed on leaves and fruit of achachairu (Garcinia humilis) in a producing region in Pernambuco, Brazil. The fungi were isolated from necrotic lesions on leaves and fruit to identify the causal agent and subjected to morphological and phylogenetic characterization. Based on these analyses, the species C. theobromicola and C. siamense were identified. The pathogenicity test confirmed that these two species are the causal agents of anthracnose on G. humilis. This is the first report of C. siamense and C. theobromicola causing anthracnose on leaves and fruits of G. humilis worldwide. Here, we also report these two species as pathogens on the fruit of G. brasiliensis (bacupari).

柽柳炭疽菌和可可炭疽菌引起柽柳炭疽的首次报道

在巴西伯南布哥的一个产区，观察到典型的炭疽病症状发生在黄藤（Garcinia humilis）的叶子和果实上。从叶片和果实的坏死病变中分离真菌，以确定致病因子，并进行形态学和系统发育鉴定。在此基础上，鉴定出了C. theobromicola和C. siamense两种。致病性试验证实，这两种都是矮叶蝉炭疽病的病原。这是世界上第一次报道在矮叶豆的叶子和果实上发现C. siamense和C. theobromicola引起炭疽病。在这里，我们也报道了这两个物种作为巴西芽孢杆菌果实的病原菌。
