Abstract
This experiment was conducted in the Plant Tissue Culture Laboratory, College of Agricultural Engineering Sciences, University of Baghdad for the period from September/2018 to July 2019. The induced callus from the cotyledon leaves of seedlings of the Spilanthes acmella plant was used in order to know the effect of chemical catalysts and Starmedium was added to Glutamine (250, 300, 350) mgters on the chemical content. After 4 weeks of planting, the primary callus was planted at 150 mg in the nutrient medium supplemented with auxin,4-dichlorophenoxy acetic acid (2,4-D) 2.0 mg.L−1 and cytokinin Benzyl Adenine (BA) 0.5 mg.L−1 at constant concentrations in the first five medium, to which the catalyst was added salicylic acid at concentrations (25, 50, 75) μmol). The second medium was added to methyl jasmonate at concentrations (25, 50, 75 μmol) of the third medium was added to Casein hydrolysate at concentrations (25, 50, 75 μmol) of the fourth medium was added to Glutamine (250, 300, 350) mg. L−1. The results showed that the treatment of nutritional medium with high concentrations of stimulants and primer led to a significant increase in the content of plant tissues (the induced callus from the cotyledons) of total carbohydrates, the percentage of protein, the content of callus from the carotene pigment and content of proline, while the comparison treatment was the most effective in vegetable tissue contents of total carbohydrates and protein percentage and content of callus from the carotene pigment and proline, as well as this confirms that all treatments led to a positive and direct increase of chemical compounds content of plant tissues of chemical traits, especially in the treatment of Salicylic acid, methyl jasmonate, casein hydrolysate, glutamine, and phenylalanine (75 micromoles, 75 micromoles, 75 micromoles, 350 mg.L−1, 150 micromoles) respectively, were followed by the treatments of Salicylic acid, methyl jasmonate, casein hydrolysate, glutamine and phenylalanine (50 μmol, 50 μmol, 50 μmol, 300 mg.L−1, 100 μmol), respectively. The aim of this study is to know the effect of Salicylic acid, methyl jasmonate, casein hydrolysate, glutamine, and phenylalanine in the induction and differentiation of callus of cotyledon leaves cotyledon leaves of Spilanthes acmella seedlings on some chemical traits in vitro.
