Microscopic Observation of the Pseudothecial Development of Mycosphaerella nawae on Persimmon Leaves Infected by Ascospore and Conidia
감나무 둥근무늬낙엽병균 Mycosphaerella nawae의 자낭포자 및 분생포자에 감염된 이병엽 상에서 위자낭각 형성과정 관찰
Abstract
In order to illustrate the role of conidia of Mycosphaerella nawae as a secondary inoculum in nature, pseudothecial development on persimmon leaves was investigated microscopically. The fungal ascospores have been believed as the primary or only inoculum source in nature, however, pseudothecia were readily formed on persimmon leaves infected naturally and artificially by conidia. The pseudothecia of M. nawae were found to form in the tissues of infected leaves while the leaves were still hanging on the trees. The size of pseudothecia were approximately 51.0~122.4
