Abstract:

An outdoor experiment was conducted to evaluate the effects of growth retardant Alar and slow-release fertilizer Osmocote applications on growth and flowering quality and some chemical constituents of chrysanthemum (Dendranthema grandiflora) cvs. (Kodiak ‘yellow’, Ivyridgf ‘white’, Auburn ‘red’ and Lansing ‘pink’). Alar at 0, 1500, 3000 and 4500 ppm as a foliar spray and Osmocote were incorporated in potting substrate at 0, 70, 140 and 280 mg kg^-1 soil. Among different treatments, 1500 ppm gave reduction in plant height, leaf area, node production or flowering and early flowering. However, the best performance was found for other characters like number branches, number of leaves per plant, maximum duration of flowering, time to marketability, flower weight, flower diameter, and number of flowers per plant. The highest recorded data was obtained in plants treated with Alar 1500 ppm on chemical constituents (chlorophylls relative content, reducing and non-reducing sugars and N, P and K percentages). The remarkable increase in growth and flowering parameters were found with Osmocote treatment at 70 mg kg^-1 soil. Therefore, we proved that all cultivars treated with 1500 ppm Alar were compact and had large flower diameters, and the best vegetative growth and flower quality was found with application of the slow-release fertilizer Osmocote at 70 mg kg^-1.
