Genotypical Variability Of Quantitative Characteristics Of The Biochemical Composition Of Fruits Of Introduced Plants Of Ericaceae And Actinidiaceae Families Within The Conditions Of Belarus
Journal Title: IOSR Journal of Biotechnology and Biochemistry (IOSR-JBB - Year 2019, Vol 5, Issue 1
Abstract
Quoted results of a comparative variability study of fourteen quantitative characteristics of the biochemical composition of fruits in cultivar rows of four species of introduced plants from the Ericaceae family (Oxycoccus macrocarpus, Vaccinium corymbosum) and Actinidiaceae family (Actinidia argeuta, Actinidia kolomikta) showed its minimum dependence of O. macrocarpus on genotype and the maximum dependence on genotype of A. arguta when the study species had similarity in the level of genetic determinacy of a number of characteristics of the biochemical composition of fruits. Parameters of accumulation of anthocyanins and leukoanthocyanins in cultivar rows of both species of Ericaceae family showed the minimum stability, whereas parameters of accumulation of ascorbic acid, observed in both species of Actinidiaceae family, showed the maximum stability. The minimum variability in cultivar rows of the majority of study species of introduced plants was established for the content of soluble sugars and the total amount of bioflavonoids, whereas the maximum variability was established for a sugar-acid index and the content of tanning substances. V. сorymbosum and A. arguta revealed a weak dependency on genotype of the content of flavonols in fruits, whereas V. сorymbosum и A. kolomikta revealed a weak dependency of the content of pectic substances with a strong dependency of accumulation parameters of the latters in O. macrocarpus and A. arguta.
