Effect of Boron and Zinc elements on some vegetative and reproductive characteristics of Rosa damascena

Rosa damascene is a plant its growth and flowering levels are severely dependent on nutrients, and adequate nutrition should be provided to achieve proper function. This research was conducted in one of the gardens around Meymand in Fars Province in a randomized complete block design with four replications. In this study, different concentrations of the element Boron (0, 1 and 2 per thousand) and Zinc (0, 1 and 2 per thousand) were sprayed in two stages, 10 days apart, one month before flowering. Different vegetative and reproductive characteristics were evaluated. Based on the results, the highest number of stamen was obtained by one-thousandth of Boron, while the lowest number of stamen was observed in the control. Although the lowest number of petals was observed in the Boron spray, however, the Zinc treatment significantly increased the number of petals. Also, the use of nutrients increased the plant length as well as the highest and lowest plant lengths was observed in the boron spray and control.The soluble solids content of petals was also significantly increased under Zinc spray application. Although the treatments did not show a significant effect on the phenol content of petals the application of micronutrients had a significant effect on the quality of Rosa damascene.
