摘要

[Objectives] Lotus (Nelumbo nucifera Gaertn) is an economically important aquatic plant in China. Fungaldisease is a serious problem in lotus cultivation. In this study, the pathogenic fungi on lotus in Nanchang City were investigated to lay the foundation for the disease control. [Methods] Lotus leaves and stems in ponds of Nanchang City were collected, the fungi on leave/stem spots were isolated and purified. Colonies morphological characters and ITS sequences were used to identify the strains. [Results] 49 strains were isolated and identified to 20 species, belonging to 12 genera. [Discussion] 15 species may firstly be reported on lotus in this study, i.e., Alternaria angustiovoidea, Alternaria compacta, Alternaria ricini, Alternaria tenuissima, Arthrinium arundinis, Botryosphaeria dothidea, Curvularia spicifera, Diaporthe australiana, Diaporthe eres, Diaporthe tectonae, Epicoccum nigrum, Fusarium fujikuroi, Neofusicoccum parvum, Nigrospora sphaerica, and Phomopsis eucommii.
