Abstract: Effects of postharvest-applied thidiazuron (TDZ) on the vases life of 7 rose cultivars (Rosa hybrida L.) were investigated. Cut rose flowers were pulse-treated with TDZ for 24 hours at 22 oC. Application of 20, 60 and 100 uM TDZ to 'Memoire' rose did not affect vase life when compared with the control (0 uM TDZ). Similarly, pulse treatments with 10 uM TDZ did not affect the vase life of cvs. 'Champagne', 'Laser', 'Magnum', 'Neon' and 'Tresor 2000' roses compared with their untreated controls, but did increase the vase life of 'First Red' by 2 days (+11.5 %). Lateral shoot development was a common side effect of TDZ treatment.
