STUDIES ON PHYSICAL AND MORPHOLOGICAL CHARACTERISTICS OF GREEN GRAM (VIGNA RADIATA) SEED, SPROUTS AND TREATED SPROUTS.

Physical and morphological characteristics represents quality of raw material, various physical properties of green gram seeds, soaked seeds, sprout and treated (10 and 20 min soaked in essential oil) sprouts were evaluated as a function of moisture content in the range of 10.24 to 89.7% d.b. The average length, width and hundred grain mass of green gram seeds, soaked seeds, sprouts and treated sprouts were 5.85± 0.2, 4.49 ±0.4mm, 6.3±0.1g, 7.01±.01, 5.93± 0.2mm,8.2±0.1g, 9.69±.01, 6.23 ±.01mm, 11.4±0.1g and 9.69±.01, 6.23 ±.01mm, 11.4±0.1g respectively. The geometric mean diameter increased from 5.85mm to 9.69mm, bulk density increased from 0.42 to 0.43 g/ml, tap density increased from 0.48 to 0.49g/ml, car's index increased from 8.16 to 12.2%, angle of repose increased from 30.96° to 33.02° and The static coefficient of friction varied from 0.48 to 0.36 against different six material surfaces and varied from 0.48 to 0.50 in treated samples due to significant effect (p < 0.05) of moisture content within the studied moisture range. Attended studies showed morphological characteriscs of green gram seeds at different seeding densities like 50g, 75g and 100g/500ml water, significant difference (p < 0.05) observed in sprout length, hypocotyl length and hypocotyl weight over different seeding densities. Significant decrease observed in sprout length, hypocotyl length and hypocotyl weight 20.6±0.1,15.3±0.4mm, 5.02±0.01g for 50g/500ml, 15.14±0.08, 9.80±0.5mm, 3.2±0.11g for 75g/500ml, mm,10.34±0.3, 5.01±0.2mm, 1.1±0.05g for 100g/500ml after changing the densities for seeding.
