Abstract
The content of photosynthetic pigments and fluorescence of chlorophylls in leaves of Dioscorea alata L. plants grown on a modified ion-exchange substrate were studied. It was found that in the variant with the addition of a fine fraction to the hydrogel substrate in an amount of 1 g/l, the Chl а content is 15 % higher than in the control. The content of Chl b and carotenoids in comparison with the control differed insignificantly. When the hydrogel was added at a concentration of 0.5 g/l, the Chl а content in all studied variants was significantly lower than the control.
Based on the investigated parameters of chlorophyll fluorescence, the most favorable conditions for the productivity of photosynthesis were in the variant with the addition of 1 g of a fine fraction and illumination of DNaT-400.
