EFFECT OF USING NUTRITION MINERALS AND GROWTH SUBSTANCE ON PHYSICAL PROPERTIES OF ORANGE FRUITS

This work was carried to investigate the characterization of orange fruits under using applications of nutrition minerals and one application of growth substance on physical properties of orange fruits at private farm in wadi el-netron, ELbehari governorate, Egypt during winter 2011to predict maturity stage of orange fruits . The physical properties including aspect ratio(AR), Area of flat surface(Af), Area of transverse surface (At), Arithmetic diameter (Da), Density (ρ), Geometric diameter (Dg), surface area (Sa), sphericity, Volume (V) and weight and the results revealed that, the high increasing percentage of orange fruits were considered as follows 9.24, 17.08, 22.65, 9.70, 27.16, 9.70, 20.45, 6.38, 24.07 and 28.84 %
