摘　　要：初步研究结果证明：郁金香灰霉病的病原是郁金香葡萄孢〔Ｂｏｔｒｙｔｉｓｔｕｌｉｐａｒ（Ｌｉｂ．）Ｌｉｎｄ．〕；病菌生长及孢子萌发最适温度为２０℃和２５℃；在相对湿度１００％条件下孢子萌发率最高；菌丝在葡萄糖、蔗糖、麦芽糖、果糖等多种碳源培养基上均能生长，但菌落形态略有差异，其中以ＰＤＡ培养基上的生长最快；该菌一般只危害郁金香，但在室内人工接种条件下，还侵染番茄、黄瓜、西葫芦等。The results showed that Tulipa gesneriana L. Botrytis rot is caused by Botrytis tulipar (Lib)Lind.This pathogen fungi,with the optimum temperature of 20～25℃ for both haphe growth and spore germination and the relative humidity near 100%,can use monosacchride,bisacchride and poly-sacchride as the sources of carbon normally.It grows well on PDA medium.Its spores or sclerotia can overwinter in soil and the host plant residue.The lower the temperature and the higher the relative humidity,the higher the rot degree. Botrytis tulipar usually infects tulip alone,but can infect tomato,cucumber and cucurbita plants by indoor inoculation.
