设想与试验过去在植物抗性研究中把植物的抗病性分为“专化”和“非专化”两大类,这在理论上是很方便的。这一传统理论认为“专化抗性”是由单基因或主效基因所控制,只对一种病原。甚至只对病原的某一生理小种表现抗性。正如其“专化”这一名字所示,它的另一个特征是对其它的病原小种没有抗性。“专化抗性”的作用是使植物完全不感病, Imagination and testing In the past, plant resistance was divided into two categories, “specialization” and “non-specialization” in the study of plant resistance, which is theoretically very convenient. The traditional theory that “specialization resistance” is controlled by a single gene or major gene, only one pathogen. Even only a pathogenic physiological raccoon show resistance. As its name implies, it is another characteristic that it is not resistant to other pathogenic races. The effect of “specialization resistance” is to make plants completely insensitive,
