The research was carried out to investigate the effect of different growth retardants to break apical
dominance in Rosa damascena. Cycocel, Alar and Ethephon at different concentrations were applied as a
foliar spray. It was observed that Alar and Cycocel showed their superiority on different morphological and
floral characteristics at lower concentrations. Maximum number of lateral shoots and flowers were
observed by the spray of Alar @ 1000ppm, which attained significant superiority over rest of treatments.
From ornamental point of view (compactness), maximum increase in size of shoots was achieved by Alar
(6.75cm) and Cycocel (6.25cm) @ 1000ppm.
