Abstract

Widely produced and marketed worldwide, orchids suffers from several diseases that have a negative effect on production. Black rot disease is among the most common and severe disease, characterized by black spots of rot on leaves, pseudobulbs and roots, which usually lead to the plant death. The world literature lists some Phytophthora species as causal agents of the disease, but there is no advanced study on the etiology of this disease in Brazil, which makes it difficult to determine an efficient control method. This work aims to contribute to the study of the etiology of black rot on Cattleya leopoldii in Brazil. Severely diseased C. leopoldii plants with typical symptoms of black rot, collected from a commercial orchid farm in Brazil, were taken to the laboratory and used to isolate the pathogen. Based on morphological characters analysis combined with molecular data, the isolates were identified as belonging to the species Phytophthora heterospora. This is the first worldwide report of P. heterospora causing black rot disease on orchids.

Phytophthora heterospora 是巴西兰花 Cattleya leopoldii 黑腐病的病原菌。
兰花在世界各地广泛生产和销售,但有几种病害会对生产造成负面影响。黑腐病是最常见、最严重的病害之一,其特征是叶片、假鳞茎和根部出现黑色腐烂斑点,通常会导致植株死亡。世界文献将一些疫霉菌列为黑腐病的病原菌,但巴西尚未对黑腐病的病因进行深入研究,因此难以确定有效的控制方法。这项工作旨在为巴西 Cattleya leopoldii 黑腐病的病原学研究做出贡献。从巴西的一个商业兰花农场收集到的具有典型黑腐病症状的重病 C. leopoldii 植株被送往实验室用于分离病原体。根据形态特征分析和分子数据,确定分离物属于异孢噬菌体(Phytophthora heterospora)。这是全世界首次报道异孢疫霉(P. heterospora)引起兰花黑腐病。
