松萎蔫病涉及各种真核与原核生物之间多种关系,其病理过程也受这些关系的影响。松树的病状不仅取决于松材线虫的数量、致病性、寄主的抗性,还受气象因子的影响。线虫与其携带天牛、致病过程、病死木的微环境同样受到这些因子的影响。笔者就病死树中的松材线虫种群及微环境和寄主抗性与菌根共生为例说明与松萎蔫病有关的生物间的复杂关系是相互关联的,它们决定了寄主树的存活和松萎蔫病的扩散。气象条件对这些复杂关系产生多方面影响,其中高温和干燥条件加速了松萎蔫病的流行。为了有效防控松萎蔫病,必须对松萎蔫病进行多方面的研究。
Pine wilt disease involves a variety of eukaryotic and prokaryotic relationships, the pathological process is also affected by these relationships. The symptoms of pine depend not only on the number of pine wood nematodes, pathogenicity, host resistance, but also on meteorological factors. Nematodes and their carrying Tian Niu, pathogenic process, dead wood micro-environment are also affected by these factors. The author illustrates the complicated relationship between organisms related to pine wilt disease and the pine tree nematode population, microenvironment and host resistance and mycorrhizal symbiosis as examples, which determine the survival and wilt of the host tree The spread of the disease. Meteorological conditions have a multifaceted effect on these complex relationships, with high temperature and dry conditions accelerating the prevalence of pine wilt disease. In order to effectively prevent and control pine wilt disease, we must carry out various studies on pine wilt disease.
