摘要：Growth retardants like BAP have a major effect in the growth and physiology ofplants. They mostly often suppress the height of stem by antagonizes the action of auxins and counteract the apical dominance and its direct application to plants fortifies cell divi-sion and growth of the dormant buds ultimately im-proving the plants bushiness. The experiment was conducted at the Ornamental nursery, Department of Horticulture, The University of Agriculture Pesha-war during the year 2018 to evaluate the effect of Benzyl Amino Purine(BAP) and its time of applica-tion on the dwarfism and flower production of car-nation using Randomized Complete Block Design with split plot arrangement. The treatments compris-ing of different concentration of BAP(0,30,60 and 90mgL-')and different time of foliar application(7, 14.21 and 28 days after transplantation).Maximum (days to flowering, number ofbranches plant', num-ber of leavesplant，leaf area（cm²）， number of flow-ers plantl, No.of petals flower! and survival per-centage (%))and minimum value of plant height (cm), fresh flower weight(g) and dry flower weight (g))were observed when BAP was applied at 90 mg L". Among foliar application, maximum plant height(g), number of branches plantl, number of leaves plantl，leaf area（cm²）and No. of petals flower-' were observed after 28 days of foliar appli-cation of BAP.While foliar application of BAP after 7 days had observed maximum value of days to flow-ering,number of flowers plant', fresh flower weight (g), dry flower weight(g) and survival percentage (%)of carnation. Based on the findings it is con-cluded that BAP @ 90 mg L-1 and foliar application after7 daysoftransplantation performed a better role in reducing the plant height and improving flower production in carnation under the agro-climatic con-dition of Peshawar valley.
