摘要

对海南、广东两省芒果细菌性黑斑病的研究表明，其症状是：叶片病斑初期呈水渍状，后转角形或不规则形，病斑表面隆起，常受叶脉限制，深褐色至黑色，边缘常有黄晕；枝条和果柄上呈现凌形，黑色溃裂，伴有胶粘物质渗出；果实上，病斑初时水渍状后转黑色，隆起，星状开裂。根据其细菌学性状、寄主范围和血清学反应的测定结果，病原菌彼鉴定为野油菜黄单胞菌芒果致病型［Ｘａｎｔｈｏｍｏｎａｓｃａｍｐｅｓｔｒｉｓｐｖ，ｍａｎｇｉｆｅｒａｅｉｎｄｉｃａｅ（Ｐａｔｅｌｅｔ，ａｌ）Ｄｙｅ］。

Abstract

A bacterial black spot of mango ( Mangifera indica L. ) was surveyed in both Hainan and Guangdong provinces.The symptoms are as follows；On the leaves,the lesion was characterized by water-soaked spots and then angular or irregular areas with raised appearance,restricted by veins,turned dark brown to black in colour later and frequently surrounded by a yellow halo; on the branches and fruit stems,the lesion appeared as a spindle black canker with gummy exudate,and on the fruit,the lesion showed water-soaked spots and then black raised areas with star-shaped cracks later. According to the determinations of its bacteriological characterstics, host ranges and serological reactions,the causal agent was identified as Xanthomonas campestris pv. mangiferaeindicae ( Patel et al.) Dye.
