Abstract
It was previously reported (Goszczynska et al., 1990) that longevity of flowers in certain rose cultivars was improved and petal senescence was postponed following post-harvest treatment of the flowers with GA3. One of the main findings was a significant decrease in leakage of electrolytes from GA3-treated petals, although several rose cultivars were insensitive to GA3 (Sabehat and Zieslin, 1994). High sensitivity of cv. Mercedes flowers to GA3 treatments and a complete insensitivity of cv. Madelon flowers (Shaul et al., 1995) stimulated investigation of GA3 effects in petals of these two cultivars. Some of the results of this investigation are described in the present report.
