Abstract :
BACKGROUND: The crop needs growth regulators in order to complete the growth, because of its important role in improving biological activity, as many researches and studies indicated that the treatment of plants with a specific growth regulator leads to the improvement of the plant structure and the yield quality and the production of seeds. OBJECTIVES: Current study was done to evaluate effect of Different level of Concentration and Time of Application Gibberellin on crop production and growth indices of Canola genotypes. METHODS: This research was done via combined analysis split plot factorial experiment based on randomized complete blocks design with three replications along 2015-16 and 2016-17. The main factor included different level of canola genotype (Hyola401, RGS003, Jerry) and sub factors consisted different concentration of gibberellin hormone (0, 50 and 100 mg.l-1) and different time of application of gibberellin hormone (Planting, vegetative phase before flowering, flowering until pod emergence). RESULT: According result of analysis of variance effect of genotype, concentration and time of application gibberellin on studied traits was significant at 5% probability level (on seed yield at 1%) but interaction effect of treatments was not significant. Mean comparison result of different level of genotype indicated that maximum studied traits were noted for Hyola401 and minimum of those belonged to Jerry. As for Duncan classification made with respect to different level of Gibberellin Concentration maximum and minimum amount of studied traits belonged to 100 ppm and control. Between different levels of time of gibberellin application the maximum studied traits was observed in vegetative phase and the lowest ones were found in ripening phase. CONCLUSION: Finally according result of current research application Hyola401 in amount of 100 ppm Gibberellin Concentration at Vegetative Phase had the highest amount of growth indices and seed yield and it can be advice to producers in studied region.
