Abstract. Based on the results of the studies, the authors note that in all variants of the experiments, regardless of the supply of soil with nitrogen, phosphorus and potassium, the maximum content of both chlorophylls and carotenoids falls on the phases of flowering and fruit formation, and the minimum during the periods of budding and ripening of artichoke seeds.
It was also revealed that a decrease in the supply of soil with nitrogen, phosphorus and potassium, especially the exclusion of one of the main elements of mineral nutrition, leads to a significant decrease in the content of photosynthetic pigments in the leaves of the prickly artichoke (Cynara scolymus L.).
Thus, in the medicinal plant spiny artichoke (Cynara scolymus L.) in developmental phases, under different conditions, mineral nutrition has a significant effect on the content of plastid pigments. It was found that the exclusion of phosphorus from the nutrient mixture led to the strongest decrease in photosynthetic pigments in the leaves of the spiny artichoke. It has also been proven that the exclusion of not only phosphorus, but also one of the main elements of mineral nutrition leads to a decrease in plastid pigments
Keywords: medicinal plant, prickly artichoke, nitrogen, phosphorus, potassium, chlorophyll a, chlorophyll b, carotenoids.
