Abstract

The purpose. To study dynamics of the content of chlorophyll pigments a and b and carotenoids k in leaves of tomato (Lycopersicon esculentum Mill.) in perspective hybrids: KDS-5 F1 (k), Enei F1, Barmalei F1, Pobratim F1, Yatran F1, Veselka F1 during vegetation in master phases of growth (budding, blooming, fruit brearing) in conditions of film glasshouses. Methods. Laboratory, vegetation, measuring-weighting, biochemical, mathematical-statistical. Results. Features of operation of pigment system of hybrids F1 of tomato depending on conditions of growing of seedling in cartridges in glass-covered ground are analyzed. Phase dynamics of the content of plastid pigments and carotenoids in conditions of film glasshouses is fixed. Indexes of pigment content in leaves of hybrid Barmalei F1, Pobratim F1, Yatran F1 are higher in comparison with other probed hybrids F1 of tomato. Conclusions. The best method of growing of seedling is use of cartridges. It is shown that the quantitative content of plastid pigments in leaves of probed crop (Lycopersicon esculentum Mill.), cultivated in film glasshouse on solar heating, — is average. It is fixed that indexes of pigment content in leaves of hybrids Barmalei F1, Pobratim F1, Yatran F1 is higher in comparison with other probed hybrids F1. That can testify to high adaptive potential of these hybrids for conditions of film glasshouse.
