Integrated Biochemical Estimation of Seabuckthorn Berries in Conditions of the Forest-Steppe Area of the Altai Krai

Seabuckthorn (Hippophae rhamnoides L.) is considered a multipurpose crop. Different parts of the plant are marked with a unique composition of nutrients and biologically active substances (soluble sugars, fatty acids, vitamins, organic acids, etc.). The study of biochemical composition is necessary for successful breeding and widening seabuckthorn utilization in medicine, food, and cosmetics industries. The paper presents the integrated biochemical features of seabuckthorn berries bred by the Lisavenko Institute in Barnaul, Russia (3 varieties and 58 hybrids). Biochemical analysis was carried out according to common research methods. We established the variability for such substances as soluble solids, sugars, vitamin C, titratable acids, oils, and sugar acids. Significant variability for sugars content (22%), vitamin C content (32%), and sugar-acid index (36%) was revealed. According to the assessment results, we selected 12 promising genotypes. We also identified genotypes combining maximum levels of 1–3 biochemical features.

Study of biochemical composition of seeds and green beans of vegetable cowpea (Vigna Ung. ssp. Sesquipedalis)

The article presents the results of investigation of the variability of biochemical parameters of seeds and green beans of vegetable cowpea accessions (Vigna unguiculata ssp. sesquipedalis (L.) Verdc.) introduced for use in breeding. Variations of biochemical parameters of seed quality and green beans (such as protein, fat, ash content, fiber, NFES) were established. New data on the fractional composition of proteins (albumins, globulins, prolamins, glutelins) from seeds and green beans were obtained. These data are of great importance for the evaluation of the starting material and the formation of a breeding program and the selection of rational strategies of individual selection from the source populations.

Изменчивость химического состава плодов черной смородины в разных регионах

В работе обобщены результаты многолетнего изучения биохимического состава плодов генколлекции сортов черной смородины в условиях ЦЧР (Мичуринск). Выделены лучшие по биохимическим показателям сорта. На основе собственных исследований и анализа литературных данных показан уровень накопления биохимических компонентов и пределы изменчивости у большого набора сортов и форм черной смородины в разных регионах.
