树木抗病的生理生化学研究进展

Advances on the Physiological and Biochemical Aspects of Resistance to Diseases in Trees

对树木受病原物侵染前后体内生化物质及其变化状况和诱发产生的多种生理生化代谢差异在寄主抗病性中作用的研究现状进行了概述。指出，目前关于树木抗病性的研究多集中在相关因素的比较分析上，有关抗病的分子机制和抗病基因定位等研究是今后深入探讨的重要方面。

Researches on the relations of tree disease resistance to the changes of bio-chemical substracts before and after the infection by pathogen,and to the differences of somemetabolisms induced by pathogens are reviewed.The current researches on disease resistanceare concentrated mainly on the comparison analysis of related factors. The molecular mecha-nisms and gene orientation of resistance to diseases in trees should be further studied.
