Technology of Cultivation of Silybum marianum Gaertn. L. (Milk Thistle)

Аннотация

This article provides an in-depth analysis of the cultivation technology of Silybum marianum Gaertn. L. (Milk Thistle), a medicinal plant valued for its hepatoprotective properties, primarily attributed to its bioactive compound, silymarin. The article explores essential aspects of milk thistle cultivation, including soil and climate requirements, sowing practices, fertilization, irrigation, pest and disease management, as well as harvesting and post-harvest processing. Additionally, it highlights modern biotechnological advances, such as in vitro and hairy root culture techniques, that can complement traditional farming methods to enhance the production of silymarin. Practical examples are provided to illustrate the recommendations for successful cultivation, making it a comprehensive guide for both small-scale and large-scale producers.

Introduction: Milk thistle (Silybum marianum Gaertn. The article also includes practical examples to aid L.) is a widely cultivated medicinal plant, renowned for its hepatoprotective properties, largely attributed to its understanding [1, 111-117]. bioactive compound, silymarin. Over the years, the Soil and Climate Requirements cultivation of milk thistle has gained importance due to The cultivation of milk thistle is highly dependent on its valuable seeds, which are used in pharmaceuticals the soil and climate conditions. These factors influence and supplements. This article presents a the plant’s growth and the quality of the harvested comprehensive guide to the technology of cultivating seeds.
