摘要

兰花是世界上栽培最多的花卉之一。巴西圣保罗包鲁植物园栽培的铁皮石斛（DT）和卡特兰（CW）出现了黑腐症状。根据病原菌的形态和分子特征，确定 DT 兰花的病原菌为 P. palmivora，CW 兰花的病原菌为 P. nicotianae。接种会引起疾病症状，病原体的重新分离符合科赫推定。

Black rot caused by Phytophthora nicotianae and Phytophthora palmivora on Cattleya wittigiana and Dendrobium thyrsiflorum in Brazil

Orchids are among the most cultivated flowers in the world. Plants of Dendrobium thyrsiflorum (DT) and Cattleya wittigiana (CW), cultivated at the Botanic Garden of Bauru in São Paulo, Brazil, presented black rot symptoms. The causal organism was identified as P. palmivora on DT and P. nicotianae on CW orchids based on its morphological and molecular characterization. Inoculation caused disease symptoms and Koch’s postulates were fulfilled by re-isolation of the pathogen.
