Abstract
The experiment was conducted on plastics pots with capacity 9 kgs soil according to completely randomized design (CRD) with three replicates and used wheat cultivar (Abu-Ghraib) and used in this experiment the plant hormone gibberillic acid (100ppm) and organic fertilizer (144 gm/pot) and (gibberellic acid 100 ppm + organic fertilizer 144 gm/ pot). The aim of this research to study the effect of gibberillic acid and organic fertilizer and (gibberellic acid 100 ppm +organic fertilizer 144 gm/ pot) with control treatment on qualitative of amino acid in grain and dry shoot of wheat plant and also to study the effect of experimental treatments on Fe, Mn, Mg concentration in wheat grain and dry shoot. The results showed: gibberellic acid (100 ppm) and organic fertilizer and (gibberillic acid + organic fertilizer) lead to new amino acids comparative with the amino acid in the control treatment in wheat grain and dry shoot. And the results also showed,The gibberellic acid treatment led to increased Fe concentration in wheat grain and dry shoot, Their values were 148.6 and 114 ppm respectively. And also for organic fertilizer treatment this led to increase Fe concentration in wheat grain and dry shoot this value were 173.3 and 175.3 ppm respectively. The treatment (gibberellic acid + organic fertilizer) showed great increase in Fe concentration in wheat grain and dry shoot also and the results showed also, gibberellic acid led to decrease of Mn concentration in wheat grain and dry shoot of plant, Their values were 112.6 and 101 ppm respectively. While the organic fertilizer led to increase Mn concentration in grain and dry shoot of wheat plants and intraction in grain and dry shoot of wheat plants and increase Mn concentration in treatment (gibberellic acid + organic fertilizer) comparative with the control and the results also showed: gibberellic acid and organic fertilizer and (gibberillic acid + organic fertilizer) increased Mg concentration in grain and dry shoot of wheat plants comparative with the control treatments, Their values were 1359 and 1569 and 1899 ppm in wheat grain respectively and 2299 , 2308 , 3859 ppm in dry shoots of wheat respectively.
