农药在植物体内的传导方式和农药传导生物学

Conduction mode of pesticides in plant and pesticide-conduction biology

农药在植物体内的传导方式是影响其使用方法和使用效果的重要因素之一。依据农药传导生物学的理论提出农药进入植物体内包括内吸和传导两个性质完全不同的过程。在植物体上的内吸应该是所有化合物均有可能发生的行为,但并不是所有化合物都能进行真正意义上的传导。具有在植物体内进行传导的化合物可以称为传导性农药以区别于内吸作用。农药在植物体内的传导既决定于化合物本身分子结构特征,也受植物解剖学和生理学的影响。故农药的传导是这两者结合的具体表现。换言之,对于一个具体的化合物而言,其传导与否并不是一个绝对的概念。它们会因植物种类的不同及其所处的生理状态不同而发生改变,甚至其传导方式也会因使用方式的不同而改变。因此,化合物的传导性应该更多地属于农药的使用技术范畴,而不仅仅是一个化合物的作用方式概念的独立表述。

Pesticides conduction mode in plant was one of the most important factors related to using method and efficiency. Based on Pesticide-conduction Biology, the paper put forward the idea that pesticides entered into plant by two entirely different processes-suction and conduction. Suction in plant was a possible behavior that all compounds can process, but it may not process conduction. In order to distinguish the compounds conducting in plant with ＂suction effect＂, they can be named as conductive pesticides. Pesticides conduction in plant was determined by both its molecular structure and anatomy and physiology of the plant. In other words, as to a specific kind of compounds, conducting was not absolute, and they would change due to different plant species, its physiological states and even the using methods. So compounds conductivity can be taken as a technique on pesticides usage rather than an independent concept on action mode.
