摘要

为了有效地保护迁地保护植物基因库,采用了各种各样的方法和途径,每种方法和途径都有其优缺点。迄今为止,利用不同的温度制度在保存植物遗传资源方面取得了相当多的经验,这主要对农业部门很重要;世界各地都建立了基因库。不幸的是,种子和其他各种植物材料的低温保存主要成功地用于农作物,而保存稀有和濒危植物物种基因库的实验并不普遍。有必要研究某些珍稀濒危物种基因库可持续繁殖的可能性。利用受保护植物的微克隆繁殖是保护其基因库的另一种方式,也是恢复自然界中正在消失的物种的先决条件。开发有效的微克隆繁殖方法是建立珍稀濒危植物离体基因库的基础,也是生物多样性保护的重要方向之一。

ADDITIONAL METHODS FOR PRESERVING THE GENE POOL OF POPULATIONS OF RARE SPECIES OF MEDICINAL PLANTS
To effectively conserve the gene pool of protected plants ex situ, a wide range of methods and approaches is used, each of which has its own advantages and disadvantages. To date, considerable experience has been gained in the preservation of plant genetic resources, which are important mainly for the agricultural sector, using different temperature regimes; gene banks have been created all over the world. Unfortunately, cryopreservation of seeds and various other plant material is successfully used mainly for agricultural crops, and experiments to preserve the gene pool of rare and endangered plant species are not so widespread. It is necessary to investigate the possibility of sustainable reproduction of the gene pool of certain rare and endangered species. The use of microclonal reproduction of protected plants is an additional way to preserve their gene pool and a prerequisite for the repаtriation of species that are disappearing in nature. The development of effective methods of microclonal reproduction is the basis of work on the creation of in vitro genetic banks of rare and endangered plant species, as well as one of the promising directions for the conservation of biodiversity in general.
