Abstract

The objective of this investigation was to study the effects of cycocel (CCC) and paclobutrazol (PBZ) on Kalanchoe blossfeldiana, L. to produce plants more compact, shorter, with a plurality of branches and inflorescences, flowering earlier, and to be more suitable as a pot plant. Different concentrations of CCC at 1000, 2000, and 3000 ppm and PBZ 50, 100, and 150 ppm were applied as foliar spray for once (after 45 days) or twice (after 45 and 60 days from planting). All treated plants were shorter with profuse branches specially the ones which have been treated with PBZ at 150 ppm twice (6.00 branches/ plant), and by the same treatment achieved the maximum number of inflorescences as it recorded 5.00 inflorescences/ plant. Sprayed plants with PBZ at 150 ppm twice gave the minimum number (125.33) of days to flowering. The total chlorophyll and carbohydrates content were increased in all sprayed plants, as it was 0.679 mg/ g FW for chlorophyll (PBZ 100 ppm twice) and 207.07 mg/ g DW for carbohydrates (PBZ 150 ppm twice). For compressed Kalanchoe plants with dark green leaves, abundant branches, abundant blooms and early blooms, paclobutrazol may be recommended at 150 ppm twice.
