Abstract
The present investigation entitled “Morphological and Biochemical characterization of pomegranate germplasm”. The objectives of this research were to study biochemical and morphological parameters of exotic pomegranate genotypes and to assess the potentiality of exotic genotype(s) in comparison with domestic growing variety(ies). A wide and significant range of variation was observed among ten pomegranate varieties for various quantitative and qualitative characters which include physical, flowering, fruiting, biochemical and nutritional characters. Under physical parameters, plant growth habit, plant height, leaf shape, leaf apex shape, leaf dimensions, petiole length were studied. Number of sepals, petals, flower size and other qualitative characters were studied under flowering parameters. Fruit morphological characters include fruit colour, shape, size, weight, aril characteristics, aril moisture per cent and fruit juice content. Biochemical analysis included total soluble solids (TSS), titratable acidity (TA), vitamin C in juice, total anthocyanin content, total phenolic content (TPC), total flavonoids content (TFC), total antioxidant activity in peel and juice of fruit, ferric ion reducing antioxidant power (FRAP), superoxide dismutase activity (SOD) in juice and pectin per cent in peel. Results indicated that ‘Shainakskii’ variety had maximum plant height (2.17 m), leaf blade length and diameter (7.77 cm and 1.84 cm, respectively), while ‘Ariana’ variety exhibited maximum fruit length (7.31 cm) and diameter (7.20 cm), fruit weight (269.7 g), aril moisture per cent (78.2 %), juice content (51.0 %) and total antioxidant activity by DPPH (76.5 %) and FRAP methods (68.5 mmol/ L Fe+2), therefore, its arils may be utilised for anardana purpose,Variety ‘Vkusnyi’ possessed maximum antioxidant activity in peel (87.0 %), thus, it may be used for pharmaceutical or cosmetic industry. Also, variety ‘Nusai’ and ‘Myatadzhy’ had lower TA and high juice content and TSS, so, it may be used for table or juice purpose. A significant and positive correlation was found between TPC, total antioxidant activity in peel and total anthocyanin content in juice.
