Abstract
Relevance and methods. During the period of mass flowering — fructification 20 collection samples of eggplant of various origins were studied for some photosynthetic and biochemical parameters in the conditions of the Apsheron Peninsula of Azerbaijan Republic. On the basis of the conducted research, samples characterized by a high leaf area (1470,3–1810,1 cm2/plant), high content of total chlorophylls (94,8–104,3 mg/plant) in the leaves and dry matter in fruits (6,2–1,9%) were selected. The size of the leaf area was determined by a portable device L1–3000 C, the content of chlorophyll in the leaves was determined by the device SPAD-502 Chlorophyllo-meter, the content of dry matter and nitrates was determined by the method of A.I. Ermakov.
Results. It was revealed that the varieties selected for photosynthetic parameters were also characterized by high productivity. Comparative characteristics of collection samples showed that the results obtained by assessing the dry matter content in eggplant varieties were higher compared to standard variety (6.2–11.9% contrary to 4.9%). Тhese distinguished samples are recommended for use by selectionist in further selection. At the same time, it is recommended to pay special attention to sample 148 (AFN-28), which exceeds the standard variety Zakhra by 2.43 times in dry matter content, 2.49 times in leaf area, and 3.30 times in total chlorophyll. It was also found that the content of toxic substances — nitrates in the fruits of the studied collection varieties was lower than the maximum acceptable concentration (MAC) provided in the regulations of the Ministry of Health of Azerbaijan Republic (24.0–82.5 mg/kg contrary to 300 mg/kg), which indicates that these samples can be used to produce eco-friendly eggplant products.
