VARIETAL FEATURES IN BIOCHEMICAL COMPOSITION OF KIWIFRUIT GROWN IN RUSSIAN SUBTROPICS
The paper shows studies results on biochemical composition of kiwi fruits that grow in Russian subtropical conditions, emphasizing their high nutritional and biological value, as well as antioxidant properties. The paper established some varietal differences in content of soluble solids, sugars (including glucose, fructose and sucrose), organic acids (citric, malic), vitamins C and P, amino acids, aromatic, pectin and mineral substances. According to the results of long-term data, we have defined the accumulation of sugars (6,22-7,85 %), pectin (0,45-0,58 %), organic acid (1,6-1,77 %), vitamin C (71,4-117,9 mg/100 g) and P (11,7-18,5 mg/100 g) in fruit pulp of kiwi. The following cvs. were selected: ‘ Ebbott' and ‘ Allison' - the sources of high content of nutrients and biologically active substances.
