Biochemical analysis of sweet pepper hybrids

The article is devoted to the results of biochemical analysis of sweet (or salad) pepper hybrids. The studies were conducted in experimental plots of the educational and research greenhouse farm “ROSHCHA” of Michurinsk State Agrarian University. The object of the study is sweet (or salad) pepper hybrids varieties such as Zvezda Vostoka (Star of the East), Knyaz' Igor', Marshal, Fel'dmarshal Suvorov and Belyy Naliv. During results analysis, standard methods for determining the biochemical composition of vegetable raw materials were used. The experimental design included three factors: sweet pepper hybrids; application of the complex water-soluble fertilizer Fertika at NPK 6.4:11:31 dose, which was compared with the control watering; two sowing dates for pepper seeds. Based on the research results, hybrids with a high amount of dry matter were identified: Marshal (41.95%), Knyaz' Igor' (41.07%), and Fel'dmarshal Suvorov (41.84%). The studied hybrids slightly exceeded the average data of the amount of total sugar and acidity of pepper fruits. The exception was Fel'dmarshal Suvorov hybrid, whose characteristics were slightly higher than that of the other variants. The application of Fertika fertilizer in the experiment increased the dry matter and sugar content in the fruits. All variants of the studied hybrids exceeded the physiological norm of ascorbic acid consumption (100 mg/day for an adult) several times. The highest content of ascorbic acid was noted during the first planting of hybrid Marshall and Belyy Naliv. When planting the crop for the second time, the indicator significantly decreased and the maximum content was noted in Fel'dmarshal Suvorov hybrid. Having also analyzed the vitamin composition of the studied hybrids, we came to the conclusion that it is recommended to grow the following sweet pepper hybrids with a high content of dry matter and biologically active substances: Marshal, Fel'dmarshal Suvorov, and Knyaz' Igor'. They are suitable for consumption both fresh and processing condition.
