Abstract: (28510 Views)
This study was conducted to evaluate the effects of paclobatrazol and cycocel on some quantitative and qualitative traits of zinnia. Seedlings were transplanted on Horticulture Department Farm , College of Agriculture, Isfahan University of Technology. The experiment was carried out in the framework of randomized complete block with 3 replications. Triats which were studied included plant height, leaf and flower number, lateral shoot number, flower diameter, lateral shoot lenght, leaf chlorophyl content, the period of the flowering, root fresh and dry weight, leaf area, root number, diameter and length, root and shoot carbohydrate. Results showed that cycocel at 1000 and 2000 ppm reduced height. Cycocel 2000ppm caused most lateral shoot and flower number and the lowest lateral shoot length. The lowest root fresh and dry weight, root number and length and shoot carbohydrate were obtained by cycoel 2000 ppm. Paclobutrazel at 30ppm resulted in the most leaf chlorophyl content. There were no significant differences between treatments related to the period of the flowering, flower diameter, leaf number and area, root diameter and carbohydrate.
