摘要
大棚黄瓜菌核病是新的病害.迄今为止,对它的发生规律在国内尚未见报道.在哈尔滨市,自1982年以后,大棚黄瓜菌核病突然暴发并逐年扩展、加重,我们对菌源、侵染途径、病害循环发展等问题,进行了如下试验.
The paper dealt with the biological characteristics and infection cycles of Sclerotinia sclerotiorum(Lib.) de Bary and Botrytis cinerea. Primary infection sources of cucumber sclerotinia blight and grey mould were ascospores and conidia. Secondary infection sources were mycelia and conidia. Plants could not be infected by pathogens in soil but in air directly. Sclerotia and conidia which overwintered and oversummered in fields or plastic sheds were infection sources of the two diseases but ascospore was not one because ascospores survived only for a short time.
