| Abstract: | The occurrence patterns of the sexual phases of 16 isolates (5 species)in Sclerotinia were studied systematically. The results were as follows: sclerotia of S. sclerotiorum germinated apothecially in spring and autumn. The sclerotial germination was influenced by the temper- ature and humidity. Developing process of apothecia was grouped into 4 stages, namely needle stage, expanding stage, funnel stage, open and flat stage. Both the time of different developing stage of apothecia and the time that apothecia discharged ascospores depended on sclerotial size, temperature, humidity and the depth of sclerotia in soil. The apothecia could live 1--60 days. The life span of ascospore was influ- enced by high temperature and strong light. The ascospores lived for more than 60 days normally. Sclerotia of S. asari and S. schinseng germinated to produce apo- thecia occasionally. Sclerotia of Sclerotinia minor did not germinate to produce apothecia in nature and in labs. |
