Genotypic variability of biochemical composition of fruits of introduced species of Ericaceae and Actinidiaceae families in conditions of Belarus

Abstract

The article describes results of a comparative study of variability of 14 quantitative characteristics of biochemical composition of fruits in sort rows of 4 species of introduced varieties of Ericaceae (Oxycoccus macrocarpus, Vaccinium corymbosum) and Actinidiaceae (Actinidia arguta, Actinidia kolomikta) families, which has shown its lowest dependence on genotype in O. macrocarpus and the greatest dependence in A. arguta while the species studied have similarities in the level of genetic determinancy of a number of characteristics of fruits biochemical composition. It has been shown that the lowest stability in sort rows of both species of Ericaceae fam. is typical of parameters of accumulating anthocyanins proper and leucoanthocyanins while the greatest stability – that of ascorbic acid, which is characterized by high variability in both species of Actinidiaceae family. Most species of introduced plants studied have the lowest variability in sort rows in content of soluble sugars and total amount of bioflavonoids in fruits, while the greatest one – in sugar-acid index and tannins content. It has been found out that V. corymbosum and A. arguta have little dependence of flavonols content in fruits on genotype while V. corymbosum and A. kolomikta – that of pectin substances with a strong dependence of parameters of accumulating the latter in O. macrocarpus and A. arguta.

“…Белорусские и зарубежные ученые сходятся во мнении, что высокие вкусовые качества и биохимическая ценность плодов без сомнения должны быть присущи перспективным сортам и формам полувысокой голубики [12,21]. Данный аспект выходит за рамки наших исследований, но обязательно должен быть учтен в последующей работе.…”
