Abstract

In the article, the results of the early assessment of tomato (n=27) and cucumber (n=14) collection samples grown in the greenhouse with polycarbonate coating are reflected according to photosynthetic indicators, and according to these indicators, information on the selection of primary donors resistant to adverse environmental factors is presented. It was determined that the leaf surface area of tomato samples is 74.9-193.4 m2/ha, photosynthetic potential is 3597.1-9283.2 m2.day/ha, specific surface density of leaves is 2.49-7.36 mg/cm2, net productivity of photosynthesis 2.29-5.91 g/m2.day, potential productivity 12.80-46.64 kg/m2, total amount of chlorophyll a and b 103.2-173.7 mg/100 g (moist mass), carotenoid content 23.0-85.3 mg/100 g, chlorophyll a/chlorophyll b ratio 1.80-3.47, Σchlorophyll a and b/carotenoid ratio 3.69-7.24, total wet biomass 0.588-1.639 s/ha, the amount of dry matter in leaves ranges from 11.7-20.9%. The variation interval of the values of the indicators studied in cucumber samples was as follows: 87.2-314.2; 2616-9426; 2.77-4.87; 2.81-4.61; 9.2-30.0; 83.4-166.4; 22.3-29.3; 1.70-2.83; 3.63-7.46; 0.501-1.624 and 10.5-16.7. Variation of photosynthetic indicators in the collection samples of tomato and cucumber in such a wide range is 8 tomatoes resistant to adverse environmental factors (lighting, cold, heat, drought, etc.) pure lines and F1 hybrids with 466, 480) and 8 samples of cucumbers (pure lines with catalog numbers 25, 62, 63, 64, 65, varieties with 16 and 23 and F1 hybrid with 58 in ETTI) were selected. These selected samples are also characterized by high nutritional value.
