The evaluation of auxin and gibberellin hormone on quantitative and qualitative characteristicsof forage corn

Application of plant hormones in the development of sustainable agriculture in recent decades has been considered and it should be integrated crop management (ICM) is investigated. To evaluate the effects of plant hormones (auxin and gibberellin) a factorial experiment in randomized complete block design with three replications in Marvdasht citywas conducted. The first factor was four levels of auxin (zero, 50, 100 and 150 ppm) and the second factor consisted of four levels of gibberellin (zero, 50, 100 and 150 ppm). ANOVA of Measurement traits showed the significant effect of auxin on quantitative traits in maize(Plant height, ear length, leaf fresh weight, fresh weight per ear and weight of forage kg/ha in level of probability 99 %. and was not significant for stem fresh weight.for the results of hormone gibberellin on trait (fresh weight of leaf, stem fresh weight, plant height, fresh weight forage, per hectare, ear length) were significant in level of probability 99 %. And stem diameter was not significant. The results of the interaction showed that was significant for forage yield (kg/ha)and fresh weight per plant and not significant for other traits. Mean comparisons of auxin hormone showed that most quantitative traits (leaf fresh weight, stem fresh weight, fresh forage weight and fresh weight per plant), the hormone auxin application of 100 and 150 ppm obtained, which is statistically no difference. Mean comparisons showed that the hormone gibberellin greatest attributes was used in 100 and 150 ppm. Results for quality traits (protein and carbohydrate ear stems and leaves) showed that increasing concentrations of the hormone increases the amount of quality traits.
