| Abstract | ||
| This experiment was conducted during 2013. The objectives were to study the possibility of buckwheatFagopyrumesculentum M. in the Iraqi environmental conditions, and the production of the effect of active phenolic compounds in the fields of medicine and pharmacy in vivo, through the use of different concentrations of some plant growth regulators. Results indicated that the application of plant growth regulators on buckwheat plants in different concentrations had significant at effect in the study. Application of salicylic acid at 60 mg.L-1 had asignificant effect on plant high and number of leaves per plant. While salicylic acid at 90mg.L-1 had superior effect in reducing days to %50 flowering and supremacy in significant toincrease in root length and dry matter of plant.Brassinolide at 10 mg.L-1 significantly effected the average number of days of plants to %50 Physiology maturity. While 20 mg.L-1 had asignificant effect on weight 1000 seeds (13.067 g)plant yield (3.492 g) biology of yield and harvest index.The application of 10 mg.L-1 of Methyl Jasmonate had asignificant effect on yield of plant. While 20 mg.L-1 of Methyl Jasmonate caused was significant in reducing average the number of days of plant to %50 physiology maturity, plant high and number of leaves per plant. Application of 30 mg.L-1 of Methyl Jasmonate had asignificant reduction in root length.While 10 mg.L-1 of MetylJasmonate caused significant increase of plant yield and harvest index. The application of 20 mg.L-1Brassinolide gave highest product for Caffeic acid, Quercetin and Rutin. While 30 mg.L-1 of Brassinolide increasedChlorogenic acid, Orientin, Vitexin and Isovitexin. The addition of 30 mg.L-1Methyl Jasmonate caused highest value for product of compounds Vanillic acid, Gentisic acid and Coumaric acid. | ||
