Study Of Some Physiochemical Characteristics Of Four Local varieties Of Maize Cultivars

Abstract

It is noticed that there are significant differences in the ratio of moisture to the studied species of grain that ranged from ( 9.5% – 10.6% ), The ratio of protein in species (106) is increased to (%11.0) and decrease significantly in the Arabic species to (%9.9), There are significant differences in the centent of the grain oil that ranged between (%2.8-%4.3), There are no differences in the content of ash in the studied grain species,The ratio of the carbohydrates is increased in the kadz species significantly (%74.9) compared at the other species. The ratio of the amylose is increased significantly in the 106 species (2.2%) and followed (23.2% - 25.2%) respectively, There are significant differences in rario of the amylo-pectin for all the studied grain species that ranged from (74.8% - 76.9 %), It is noticed the significant differences between the PH values for the 106, kadz and Arabia species while no significant differences in these values between the ksdz and Al-Shahba species that ranged fromm (5.0 – 5.5). The result of measuring the weight of thousand grain is showed significant differences in the tow kadz and Al-shahba species ranged (24.8 , 48.0), respectively , while did not show any differences in each of the ( 106 ) and Arabia species, The results of the tow kadz and Al-shahba species are increased that ranged between (52.7 , 52.8 kg , cmz respectively , while it decreased in the tow (106) and Arabia species (51.0,51.8 kg.cmz) respectively, It is noticed that there are significant differences between the lengths of grain , The kadz gain is the longest (6.5 mm) and the Arabia species is the shortest (5.2 mm), There are significant differences between the diameters of the studies grain species : The 106 and kadz species are ( 1.9 mm and 2.1 mm ) diameters : respectively, While there are no significant differences in both species Alshahba and Arabia (2.2 mm and 2.3 mm diameters) respectively, The results of the PH measuring are showed no significant differences between Arabia and Al-shahba species , while this value is (4.9, 5.4) in the 106 and kadz species ( 5.5 ), The concentration of the pigments is increased significantly in Al-shahba species (6.8 ppm) more than both the 106 and Arabia while this value is decreased significantly in the Arabia species (5.8)
