Morphological, biochemical and qualitative changes associated with growth and development of pomegranate fruit (Punica granatum L.)
First Online 22-12-2015|
Morphological, biochemical and qualitative changes occurred during growth and development of three pomegranate cultivars were studied at AICRP on Arid Zone Fruits, Department of Horticulture, MPKV, Rahuri. Various changes were determined at 30 days intervals from anthesis till harvest. The pomegranate fruit in all cultivars showed single sigmoid pattern of growth. The size, weight and volume of the fruit of each cultivar increased while the specific gravity increased earlier and then decreased after 90 days in Cv. Bhagwa and after 120 days in Cv. Mridula and Sel-4 to less than one. The elongated oval shape of fruit at the early stage changed to round with prominent suppressions on sides at maturity stage. From those studies, it was revealed that the pomegranate fruits showed colour changes from initial green to orange red and high red at maturity stage and it can be harvested within 150 to180 days. Among biochemical changes the total soluble solids and TSS: acid ratio increased while the acidity decreased with the advancement in the age of fruit. The total anthocyanin content in arils of pomegranate fruit increased with the advancement in the age of fruit. For qualitative changes, it was found that the percentage of arils and the juice content of arils increased, while the percentage of rind, rind thickness and seed content decreased gradually with the advancement in the age of fruit in each cultivar under study. The percentage of juice content was higher in Mridula at all the stages of maturity than Bhagwa and Sel-4. Seed hardness increased as the fruit matured. Incidence of internal breakdown of arils was noticed earlier in Bhagwa.
