Clonal Micropropagation Technique оf Stachys Sieboldii Mig

This article gives information about nontraditional stachys plant (Stachys sieboldii Mig.), its cultivation and newmethod of plant propagation - clonal micropropagation. The most valuable parts of the plant are nodulesformed on the stolons, but leaves and stems can also be used in food. Stachys sieboldii Mig. (Labiatae) is native to Northern China and widely distributed in North America, Asia, and Europe. S. sieboldii has been used in Chinese folk medicine for the treatment of ischemic stroke, senile dementia, and various gastrointestinal problems. The article describes development of an efficient in vitro plantlet regeneration system from tubers of Stachys sieboldii (Miq.). Because of unfavorable climate of the Russian Federation, stachys can be multiplied in vegetative wayonly. It is conventionally propagated by its tubers, but this method is not practical for large-scale clonal propagation. The methods of biotechnology help to reduce energy costs and increase significantly the reproduction rate. Proper passage of clonal micropropagation stages (introduction into culture, proper propagation, rooting and adaptation to in vivo conditions) make it possible to obtain quality planting material at low material and time costs.In vitro techniques offer many unique advantages over conventional propagation methods such as disinfection, rapid multiplication, expeditious release of improved varieties, production of disease-free plants, non-seasonal production throughout the year.
