Changes in physico-chemical attributes of pomegranate during fruit growth and development

摘要

Changes occurring during fruit growth and development of 'Maias Yazdi' pomegranate cultivar in Iran were studied. Fruit growth patterns were determined at 10-day intervals by measurement of diameter, length, fresh and dry fruit weight and seasonal relative growth rate were calculated. Pomegranate fruit shows a sigmoid pattern of growth both on diameter and length basis, while fresh and dry weight of fruit were accumulated linearly until harvest. Total soluble solids and pH in the arils of fruit increased, while total acidity decreased throughout the growing season.
