| 摘 要： | 1989年11月~1990年3月,从浙江省不同地区的大麦(浙农大5号)、小麦(浙麦3号)以及麦田土壤中,分离鉴定到Pythium.dissotocum,P.irregulare,P.polypapillatum(国内新记录),P.spinosum和P.ultimum等5种腐霉。接种试验表明,分离到的5种腐霉对供试大、小麦都能致病,引起根腐、根尖变褐和坏死、第一片叶卷曲,抑制植株生长,造成植株各部不同程度的矮化和变短。 |

| Abstract: | Five species of Pythium were isolated from diseased roots of wheat, barley and wheat-field soils at different locations in Zhejiang Province from November of 1989 to March of 1990. They are:P.d issotocum,P. irregulare,P. polypapillatum, P.spinosum and P.ulti-mum. In inoculation tests, all five species isolated from wheat and barley roots were pathogenic to their hosts.which caused root rot, root tip browning and necrosis,distor-ture of the first true leaves, suppression of plant growth and various stunting as well as shortening of different parts of plant. |
