Gamma irradiation at 0.025 kGy increased the respiration rate of ‘Golden Gate’ cut roses. The irradiation followed by cold storage (at 4°C) brought down the respiration rate after storage duration of 3 days. The respiration rate was found maximum in the sucrose (3%) pulsed flowers immediately after pulsing. However, the rate of respiration is decreased in all the treatments. The irradiated flowers recorded lowest amount of respiration at senescence and the vase life was maximum in these flowers.
