植物的生化抗病性是揭示植物抗性机制、寄主、病原菌相互关系的重要内容。本文系统地综述了近年来国内外有关研究的主要结果,包括先天存在和病菌侵染后所诱发的生化抗性及生化反应。 1 先天存在的化学抗性 1.1 植物在其环境下分泌的抑制剂植物通过地上和地下部分分泌各种抑菌物质。一些植物叶片上所产生的菌毒素分泌物(Fungitoxic exudtes)在一定浓度下可抑制
The biochemical resistance of plants is an important part of revealing the mechanism of plant resistance and the relationship between hosts and pathogens. This article systematically reviews the main results of recent studies both at home and abroad, including biochemical resistance and biochemical reactions induced by innate and pathogen infection. 1 Ancillary chemical resistance 1.1 Inhibitors secreted by plants in their environment Plants secrete various bacteriostatic substances both above and below ground. Fungitoxic exudtes produced on some plant leaves can be inhibited at a certain concentration
