植物的生化他感效应及其在湿地研究中的应用

信息传递是生态系统的基本功能之一。自然界的一切生物体都具有某些共性,动物体靠神经和激素调控生命活动,而植物体主要靠根尖和顶尖的激素起调控作用,但也存在着电位的传导通路。神经系统的调控过程是兴奋与抑制的协调过程,生态系统的调控过程是相生与相克的协调过程,生态系统的化学调控是指生物体产生的生物活性物质能在生物体之间传递信息并导致生物体的相互作用。植物的生化他感作用是植物之间传递信息的一种方式,它和信息的功能具有惊人的相似性。早在公元前5世纪和3世纪,Ｄｅｍｏｃｒｉｔｕｓ和Ｔｈｅｏｐｈｒａｓｔｕｓ就分别提到植…

Aiielopathic Effect and Its Use in Wetland Study.

Allelopathy is the way that plants transmit messages among them. Plants produced biological active material to transmit messages and resulted in mutual promotion and restraint between living things. This is a new domain in Chemistry Ecology. This paper introduced the concept of allelopathy, allelopathic material, function characteristic and function mechanism, analysed the cause which affect the allelopathic material to produce, to release and to act on, and inquired into use the allelopathic effect of in wetland ecosystem. In the basis of the previous study, the paper searched for new methods to study allelopathy in wetland(Tissue Culture and Man-made Imitate Experiment) and the prospects for researches of allelopathic effect in the wetland.
