Content of plastid pigments in leaves of seedling of indeterminant hybrids F1 of tomato (Lycopersicum esculentum Mill.) in conditions of glass-covered ground

Abstract

Goal. Compare the performance of six promising F1 Ukrainian breeding hybrids with regard to the content of chlorophyll and carotenoids in tomato plants and their productivity for a method of growing seedlings in soil under closed soil conditions. Methods. Laboratory, vegetative, measuring-weight, biochemical, mathematical-statistical. Results It has been established that the content of plastidic pigments in the leaves of plants of F1 tomato hybrids of Ukrainian selection changes in ontogenesis depending on their biological characteristics. Conclusions Influence of the method of growing seedlings in the soil on the content of plastid pigments (chlorophyll a, b and carotenoids k) in F1 tomato hybrids in a film greenhouse in solar heat. The highest figures were on the sheets of the Barmale F1 hybrid, the Yatran F1, the KDS-5 F1.
