异速生长及其在道地药材研究中的应用展望

Allometry: a Perspective for Research on Dao-di Herbs

异速生长是有机体某一部分或某一指标的不等速生长,反映了生长和分配之间的数量关系,是现代生态学的重要概念之一.植物的异速生长与表型可塑性紧密相关.目前异速生长关系在植物研究中的应用主要包括:对生境的响应、繁殖策略、种内种间竞争等方面.将异速生长概念引入道地药材研究,可以在指导道地药材的适生地选择、药用部位及化学成分的积累和科学栽培管理等实践方面发挥作用.

As an important concept in modern ecology, allometry is the differential growth of parts or metrics of an organism and refers to the numerical relationship between growth and allocation. Plant allometry has a close relationship with phenotypic plasticity. The application of allometric relation in plant research includes response to different habitats, reproductive strategy, intraspecific and interspecific competition, and so on. It could be useful to introduce the allometry into the practice of choosing suitable habitat, accumulation of medicinal parts biomass and chemical constituents, as well as scientific cultivation and management on Dao-di herbs.
