摘要
介绍了近年来泡桐丛枝病研究取得的一些进展,主要包括病原类菌原体(MLO)的检测和鉴定、病原致病机理、病原在树体内的分布和季节变动规律、寄主抗病性鉴定、治疗药剂的筛选等方面的最新研究结果和动向。并且根据新提出的泡桐丛枝病原MLO浸染循环模式,探讨了我国发生泡桐丛枝病流行的关键因子,以及今后防治的策略问题。
The recent advances in the research on paulownia witches' broom disease caused by mycoplasma-like organism(MLO) are introduced and evaluated in this paper, mainly involving pathogen MLO detection and identification, its pathogenic mechanism, its distribution and seasonal fluctuation, the resistant appraisal of Paulownia sp. , the screening of chemicals for disease therapy etc. The key factors associated with the disease epidemics and some strategies for the disease control are discussed as well, based on a newly-proposed model of the MLO infection cycle.
