Effect of Different Lighting Environments on the Biomass and Dry Matter Content of Raw Materials of Chelidonium majus L. (Papaveraceae) Under Cultural Conditions

In the introduction and cultivation of plants, it is important to take into account factors in naturalgrowth conditions.This is ofgreat importance in many respects, ensuring the normal course of the strategy of adaptation of plants to cultural conditions, while preserving their beneficial properties, including the quantitative and qualitative indicators of secondary metabolites.Chelidonium majus L. (Russian: Chistortel bolshoy; English:greater celandine), a member of the Papaveraceae family, is a medicinal plant thatgrows naturally mainly in temperate regions.In Uzbekistan, this plant is used to treat various diseases of humans and domestic animals.Since there are no natural reserves of Chelidonium majus L. in Uzbekistan, it wasgrown in plantation conditions and the role of environmental factors on the biomass indicators of medicinal raw materials during thegrowing season was assessed.It was observed that the biomass indicators of the raw material organs of the plant initially increased depending on the age of its vegetation and sharply decreased in the last vegetation year.It was found that the raw material biomass and dry matter content of the plantgrown under artificial shade was significantly higher than that of the plantgrown under direct sunlight.
