Abstract:
The Studies on changes in biochemical attributes during growth and development of ber (Zizyphus mauritiana Lamk.) fruit cv. (Narendra Ber Selection-2) was conducted during growing season of 2019-20. The fruits on tagged current season shoot were harvested at 21, 36, 51, 66, 81, 96, 111, 126, 141, 156, 171 and 186 days after fruit set. Samples were collected from Main Experiment Station, Horticulture and transported to the post graduate laboratory of Department of Fruit Science, College of Horticulture and Forestry, ANDUA&T, Kumarganj, Ayodhya, Uttar Pradesh. The objective was to probe the pattern of biochemical changes in developing ber fruits. The outcomes reveal that total soluble solids increased from 1.04% to 17.94% during 186 days of fruit growth and development whereas acidity content continuously decreased and recorded 0.39% on 21^th day and 0.14% on 186^th day of growth and development. Ascorbic acid content increased from 3.29 mg/100g to 90.26 mg /100g of fruit. Reducing, Non-reducing and total sugar content significantly increased from 0.22% to 4.76%, 0.11% to 5.77% and 0.35% to 10.87%, respectively. Moisture content showed decreasing trend and was maximum 71.12% on 21^st day and minimum 65.79% on 186^th day of observation. An abrupt decrease in chlorophyll content was recorded with growth and development of the fruit.
