Abstract

In order to evaluate the responses of two ecotypes of Damask rose (Rosa damascena) to exogenousethylene, an experiment was conducted based on a completely randomized design (CRD) at the laboratoryof Postharvest Physiology, Tarbiat Modares University, Tehran, Iran. Damsk rose cut stems containgflower buds and/or open flowers, single buds, or multiple flowers were exposed to exogenous ethylenefor 24 h. Plant organs were placed into hearmatically seald glass chambers, where ethylen was injected, toachieve 0, 1, 2, 3, and 4 μ l/l concentrations. Biocehmival characteristics, enzyme activities andmorphological characteristics including flower life, contents of anthocyanin, flavonoide, and PROLINE weredetermind in KASHAN and AZARAN ecotypes of Damask rose. The lowest psotharvest life was observed at 3and 4 μ l concentration of ethylene and the highest abscission was observed in AZARAN ecotypes at aconcentration of 4 μ l/l of ethylene after four days. Anthocyanin and PROLINE content and catalase activityreduced in both ecotypes studied. For both ecotypes, the lowest content of anthocyanin, PROLINE and thelowest catalase activity (48/77 Δ A 240/mg protein) were observed in those treated with ethylene at 4 μ l/l. The highest malondialdehyde (3. 63 μ mol/g petal fresh weight) was found in AZARAN ecotype flowerstreated with 4 μ l/l ethylene concentration. Decrease of TOTAL PROTEIN in KASHAN flowers (0. 32 mg/g freshpetal) was much less than that in AZARAN flowers (0. 2 mg/g fresh petal). Based on these results, KASHANcould be recommended as a tolerant ecotype to be used in breeding programs.
