摘　　要：桉树青枯病害是危害桉树生产的主要病害,近年来桉树青枯病的流行和发生对我国南方桉树产业造成很大经济损失。本文对当今主要桉树青枯病病害特点,青枯病的发生和流行因素,青枯假单胞杆菌对寄主桉树的致病机制及对抗病的差异和抗病机理等研究成果和现状作一概述,并就存在的问题提出相应的建议。Bacterial wilt caused by Ralstonia solanacearum is a primary disease to Eucalyptus. The occurrence in Eucalyptus has brought great damages in south provinces of China. This paper reviewed the advancement involved in Ralstonia solanacearum colony characters, the symptom and characteristics of the wilt, the mechanism of pathogenesis induced by the bacteria and resistance expressed by the host trees, and the variations in resistance among tree species, clones and virulence among pathogen isolates, and the host-pathogen interactions. The current wilt control measures and some important aspects of research proposed for the future were suggested.
