摘要:

采用柑橘离体叶片和果实室内人工接种柑橘蒂腐病菌的方法建立柑橘种质抗柑橘蒂腐病菌扩展能力的评价方法,对不同柑橘种质进行抗扩展能力评价,并采用病情指数法、病斑平均直径法和聚类分析方法对柑橘种质进行抗性分级。3种分析方法均将73个柑橘种质划分为5类:高抗、抗病、中抗、感病和高感,未发现免疫种质。柠檬和柚子类种质大多数为高抗品种,甜橙类和宽皮橘类易感病。

关键词: 柑橘, 柑橘蒂腐病菌, 抗扩展能力

Abstract:

To evaluate the anti-expansion capacity of different citrus germplasm against Diaporthe citri. In order to evaluate the anti-expansion capacity of 73 citrus germplasm,this study selected the in vitro citrus leaves and fruits to establish evaluation system. The resistance was evaluated with the methods of disease system clustering analysis,average diameter of the speckle and disease index method. The 73 citrus varieties were grouped into five groups:High resistant,medium resistant,resistant,susceptible and high susceptible varieties taken advantage of three analysis methods. Most of lemon and grapefruit varieties were highly resistant,sweet orange and Citrus reticulate was susceptible to D. citri.

Key words: citrus, Diaporthe citri, anti-expansion capacity
