Abstract

The article is devoted to the selection of 28 eggplant collection samples cultivated in the open field according to photosynthetic indicators in the seedling phase (39-44 days old) and the evaluation of the green and orange-red fruits of 3 sweet pepper samples cultivated in the greenhouse with polycarbonate coating according to the biochemical composition in the technical maturity phase. In the article, the comparative biochemical characteristics of the fruits of the eggplant collection samples during the period of technical maturity were studied, and the nutritional value of the samples that differed according to the adaptability indicators was evaluated. It was determined that the leaf surface area of eggplant variety samples is 176.6-489.7 m2/ha, photosynthetic potential is 7400-19100 m2.day/ha, leaf specific surface density (SDS) is 2.06-4.15 mg/cm2, photosynthesis net productivity 1.67-3.72 g/m2.day, total amount of chlorophyll a+b (ƩXl) 85.0-173.3 mg/100 g (wet weight), amount of carotenoids (Kar) 20.9 -29.1 mg/100 g, the value of Xl· a /Xl·b and ƩXl/Kar ratio is 2.36-3.78 and 4.28-7.28, respectively, the amount of total wet biomass is 0.54-2, 45 s/ha, and the amount of dry matter in the leaves varies between 9.6-15.9%. In the samples of the eggplant collection, there was a possibility to choose 6 samples that differed according to the adaptability indicators of such a wide variation of photosynthetic indicators, in which YXSS 2.79-3.59 mg/cm2, Xl· a /Xl·b 3.23-4.28, ƩXl/ Kar 3.73-5.03, ƩXl 143.3-173.3 mg/100 g (wet mass), dry matter content in leaves was 10.9-15.9%. It has been shown that these selected samples are also characterized by high nutritional value. It was noted that despite the fact that the amount of dry matter in green pepper fruits (8.3-10.3%) is higher than that of red-orange fruits (7.8-9.54%) in all three variety samples, the amount of sugars in them is 1.11-1 ,25 times, and the amount of extractive substances was 1.04-1.13 times lower. The lowest amount of toxic substances-nitrates was recorded in green fruits of sample 76 (pure line) (110.2 mg/kg), and the highest amount was recorded in sample 77 (14x81 hybrid) (171.2 mg/kg).
