| 中文摘要: |
| 到现在为止全世界已发现loo余种腐霉。我国已报道54种。在我国31个省、市自治区中,仅宁夏和西藏2个自治区未见报道过腐霉。最近我们从宁夏回族自治区土壤和植物病根用多种方法进行分离,得到259株,鉴定出10个种。它们是:瓜果腐霉Pythium aphanidermatum (Edson) Fitzpatrick、链状腐霉P. catenulatum Matthews、畸雌腐霉P. irregulare Buisman、寡雄腐霉P. oligandrum Drechsler、侧雄腐霉P.paroecandrum Drechsler,缠器腐霉P. periplocum Drechsler、无序腐霉P. perplexum Kouyeas & Theohari、角柄腐霉P. salpingophocum DrechsIer、终极腐霉P. ultimum Trow和钟器腐霉P. vexans de Bary。它们全是宁夏地区新记录种。其中无序腐霉还是我国新记录种。本文仅描述了无序腐霉,对其余9个种进行了讨论.有些种类除从土壤中分离到以外,还见于一些寄主植物:大葱Allium fistulosum L.、韭葱A. juncea L.、芹菜Apium-graveolens L.、油菜Brassica campestris L.、雪里蒸B. juncea (L.) Czern et Coss var.crispifolia Bailey白菜B. pekinensis Rupr.、辣椒Capsicum frutescens L.、胡萝卜Daucuscarota L. var.saliva DC.、草每Fragaria ananassa Duchesne、番茄esculentum Mill.、菜豆Phaseolus vulgaris L.和萝卜Raphanus sativus L.。以“腐霉名称:寄主名称”的格式列出如后:瓜果腐霉:胡萝卜;链状腐霉:胡萝卜;寡雄腐霉:白菜和辣椒;侧雄腐霉:大葱、芹菜和白菜;缠器腐霉:韭葱;终极腐霉:大葱、韭葱、油菜、雪里蕻、白菜、辣椒、胡萝卜、草墓、番茄、菜豆和萝卜。在我国,这些腐霉从前述寄主上分离出均属首次报道。 |
