Abstract

柑桔黑星病菌子囊殼形成與發育受氣象因子影響甚大。下雨、溫度、日曬、露水及土壤濕度均能影響子囊殼形成與發育。長期間下雨，不利於子囊殼形成。低溫、長期日曬與雨量稀少均能遲緩子囊殼發育之時間。溫度21~28℃之間，最適於子囊殼形成與發育。 The formation and development of perithecia of the citrus black spot fungus, Guignardia citricarpa Kiely, on the fallen dead leaves of citrus were found mainly influenced by temperature and rainfall. No perithecia developed at temperatures below 7°C or above 35°C. At 14° C, perithecia, asci and ascospores were observed 14, 32 and 42 days, respectively, after citrus leaves were detached and received alternative wetting and drying treatment daily.
