景天属植物研究综述

Advances in research on plants in Sedum

为了更好地研究、开发和利用我国景天属植物资源,通过查阅近30年有关景天属植物研究的相关文献资料,对其进行了分析研究。全球共有景天属植物约4 70种,我国拥有150种以上。景天属植物繁殖容易,可采取扦插繁殖、种子繁殖和组织培养等方式进行,对栽培基质没有严格要求。景天属植物因种类丰富、适应性强、耐高温、干旱和水淹并具有一定的抗寒性而被广泛应用。其体内富含营养成分和药用成分,常被民间用作药材;在园林中主要应用于建筑屋面绿化、地被及边坡绿化、花坛、花境等。综述了景天属植物的主要研究成果,并对未来的相关研究和应用进行了展望。

In order to research, develop and use Sedum plant resources in China, the relevant literature in the past 30 years were collected and analyzed. There are about 470 kinds of Sedum plants in the world and about 150 kinds in China. Sedum plants are easy to propagate through cuttings, seed breeding and tissue culture, and they are not strictly required for cultivation substrate. Sedum plants have strong resistance to high temperature, drought and flooding, have cold resistance at a certain degree, and their kinds are rich, so they are wildly used. Sedum plants are rich in nutrients ingredients and chemical ingredients, so they are often used as folk medicinal materials. In gardens, they are mainly used in roof greening of building, ground and slope greening, flower beds, flower border, and so on. The main research results on Sedum plants were summarized, and the future study direction was prospected.
