Abstract

The objective of this investigation was to study the effects of cycocel and paclobutrazol on kalanchoe and scarlet sage to produce plants more compact, shorter, with a plurality of branches and inflorescences, flowering earlier, and are more suitable as a pot plant. *Methods & Results: Two outdoor pot experiments were conducted at Mansoura Research Station, Horticulture Research Institute, Agriculture Research Center, during two successive seasons (2014/2015 and 2015/2016). 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, and by the same treatment achieved the maximum number of inflorescences/ plant. Sprayed plants with PBZ at 150 ppm twice gave the minimum number of days to flowering. The total chlorophyll and carbohydrates content were increased in all sprayed plants. *Conclusion: For compressed kalanchoe and scarlet sage plants with dark green leaves, abundant branches, abundant blooms and early blooms, spraying paclobutrazol be recommended at 150 ppm for twice, between the first time of spraying and the second 15 days.
