Abstract

Mineral status of the granulated and non-granulated trees showed that in the leaves of granulated trees the percentage of calcium and boron was significantly higher than in the leaves of non-granulated trees. However, the values for phosphorus, magnesium, zinc, manganese and boron were significantly lower in the granulated trees.

Mineral composition of the granulated and non-granulated fruits showed that the percentage of phosphorus’ magnesium, zinc, manganese copper and boron in the granulated fruits was significantly lower as compared to non-granulated fruits. However, calcium percentage was found to be higher in the granulated fruits.

Soluble carbohydrates were lower in the pulp of granulated fruits as con-pared to non-granulated fruits. However, starch, lignin and pectin were higher in granulated fruits.
