摘要

在伊朗克尔曼省吉罗夫特县的商业田间，观察到了大蒜茎部和球茎的腐烂。从有症状植物中分离病原菌，通过形态学和生化特征鉴定为羊草Rahnella perminowiae，通过特异引物和16S rRNA、gyrB和atpD基因序列分析确认病原。通过对大蒜和洋葱叶片和鳞茎的接种试验，两次证实了分离株的致病性，导致了perminowiae的症状再现和再次分离。这是首次报道由perminowiae引起的大蒜茎部和球茎腐烂。

Stalk and bulb decay of garlic (Allium sativum L.) caused by Rahnella perminowiae in Iran

Stalk and bulb decay of garlic (Allium sativum L.) was observed in commercial fields in Jiroft County, Kerman Province, Iran. The causal agent was isolated from symptomatic plants and identified as Rahnella perminowiae based on its morphological and biochemical characteristics and confirmed by specific primers and sequence analysis of 16S rRNA, gyrB and atpD genes. The pathogenicity of the isolates was confirmed twice through inoculation experiments on garlic and onion leaves and bulbs, which resulted in the reproduction of symptoms and re-isolation of R. perminowiae. This is the first report of stalk and bulb decay of garlic caused by R. perminowiae.
