Studies on the pattern of changes in physical characters of developing ber (Zizyphus mauritiana Lamk.) fruits

Abstract

The present investigation entitled “Studies on changes during growth and development of ber (Zizyphus mauritiana Lamk.) fruit cv. (Narendra Ber Selection-1)” was carried out during the year 2016-2017. The studies comprised experiments namely. Studies on the pattern of changes in physical characters of developing ber fruit. The study revealed that fruit length increased from days of fruit setting (0.49) cm to (4.51) cm at 168 days after fruit setting. Breadth of the ber fruit increased continuously from fruit set (0.38) cm to (4.66) cm at maturity. An increase in weight was observed during entire period of growth and development but marginal increase (37.24) g was at harvesting stage of fruit growth. The volume of fruits increased continuously during entire phase of growth (0.71) to 37.46 (cm3). The pulp weight is increased gradually from 91th days to maturity and the seed was traceable only from 91th days after fruit set and weight of seed was increase gradually till 168th days. Specific gravity, which first increased at mid of November then decreased when fruits proceeded toward at harvesting stage.
