Bananas are the most widely produced fruit in the world. Crown rot, one of the main postharvest diseases of banana fruit, causes significant losses during storage, transportation, and marketing. Different fungi, especially species of the genus are associated with this disease. isolates were obtained from asymptomatic fruits in the states of Alagoas, Ceará and Pernambuco, Brazil. On Potato Dextrose Agar (PDA), the isolates initially produced moderately dense grayish-white mycelium, then turned olive green to grayish-black, with olive-green or black reverses. The fungal isolate was classified as and based on morphological and multigene (, and ) phylogenetic analysis. Pathogenicity tests were performed by inoculating mycelial discs containing pathogen structures on banana fruits, confirming Koch's postulates. This is the first report of and causing crown rot disease in banana plants in the world.

巴西首次报道 Lasiodiplodia hormozganensis 和 Lasiodiplodia laeliocattleyae 引起香蕉果实冠腐病


香蕉是世界上生产最广泛的水果。冠腐病是香蕉果实采后的主要病害之一，在贮藏、运输和销售过程中造成重大损失。不同的真菌，特别是该属的物种与这种疾病有关。分离株是从巴西阿拉戈斯州、塞阿拉州和伯南布哥州的无症状水果中获得的。在马铃薯葡萄糖琼脂（PDA）上，分离株最初产生中等密度的灰白色菌丝体，然后变成橄榄绿至灰黑色，反面为橄榄绿或黑色。根据形态学和多基因（和）系统发育分析，真菌分离株被分类为 和 。通过在香蕉果实上接种含有病原体结构的菌丝盘进行致病性测试，证实了科赫的假设。这是世界上首次报道并引起香蕉植物冠腐病。
