Fruit growth and development of Burmese grape (Baccaurea sapida Müell. Arg.)

Abstract

Burmese grape (Baccaurea sapida Muell. Arg.) is a minor underexploited fruit crop under the Euphorbiaceae family. In the present investigation an attempt has been made to under the changes in physical and bio-chemical properties during the growth and development period of the fruit. The physical parameters like fruit length, breadth, weight, peel weight, seed weight and pulp percentage increased significantly till maturity. The bio-chemical properties like total soluble solids, total sugar and reducing sugar also increased significantly, while the acidity and pH decreased with the maturity. However, non-reducing sugar did not show a significant increase. The colour of the fruit was green during initial stage and it changed gradually to lighter shades through different shades of green and yellow green and attainted yellow shades at maturity. The specific gravity of the fruit increased till last stage of harvest.
