以日本(XC25和 XC29)和南京(XC31)菌株作对照,对从福建柑桔主要栽培品种上分离的28个柑桔溃疡病菌株进行培养性状,形态、生理生化、血清学,噬菌体敏感性和致病性的比较研究。试验初步表明,福建的柑桔溃疡病菌属于毒力较强的 A 致病型,且具有一定的分化。试验还表明,柑桔品种的抗病性变化较大。有感病、中抗和抗病等各种类型。在研究溃疡病菌菌系分化时,应选择中抗品种作为鉴别品种,采用无伤痍接种法较好。
In this study, 28 citrus canker strains isolated from the main cultivars of citrus in Fujian were tested for their traits, morphology, physiology and biochemistry, serology, bacteriophage sensitivity, and cell culture using Japanese (XC25 and XC29) and Nanjing (XC31) Comparative study of pathogenicity. Preliminary tests show that, Fujian citrus canker bacteria belonging to a stronger virulence A-type, and has some differentiation. The test also showed that citrus varieties have a greater resistance to disease. There are various types of illness, resistance and disease resistance. In the study of bacterial strains of ulcer pathogen differentiation, should be selected as anti-resistant varieties of varieties, non-invasive 较 vaccination method is better.
