樟属植物化学型研究概况

Discuss the Relative Question of the Chemical Type in Cinnamomum Plants

为今后樟属植物化学型的研究以及不同化学型植物的合理利用提供指导,在分析植物化学型的基本概念以及化学种类的基础上,着重对樟属植物化学型的特点以及产生机制进行了探讨,并提出了今后樟属植物化学型研究的方向。结果认为化学型是樟属植物各个种的共性和普遍现象,有性繁殖后代会发生化学变异;化学型的产生是环境和遗传共同作用的结果,同时与生长发育阶段有关;不同化学型由于其主成分不同导致其在医药、化学以及香料等工业中的应用不同。同时认为今后应该从以下几个方面进行研究:①研究樟属不同化学型形成的机制;②找出促使不同化学型产生分化的因素;③找出不同化学型形成的关键酶基因,并建立相应转基因体系;④加强不同化学型良种的选育工作;⑤建立幼苗时期不同化学型客观的鉴定体系。

To provides guidance to the research and the application of chemical type in Cinnamomum plants on some remaining problems.Analyzed of concept of the chemical type and which compound can come into being chemical types,and discuss the mechanism and characteristic of the chemical type formation in Cinnamomum plants,and brought forward in the future research direction of chemical type in Cinnamomum plants.Chemical type is the all-pervading phenomena in Cinnamomum plants.Chemical components of leaf oil from reproductive progenies of Cinnamomum plants are different.The formation of chemical type is the result of the interaction between environment and genes,and related of developmental stages.Different chemical types have different applications in pharmaceutical,chemical and spices industries.In the future the chemical type in Cinnamomum plants should be studied from the following aspects：① Studying the formation mechanism of the chemical type in Cinnamomum plants.② Studying the affect factor of the formation of different chemical types.③ Studying genes of key enzyme different chemical types,and establishing transgenic systems.④ The good breeding of different chemical types.⑤ The Identification of the different chemical types seeds.
