Abstract

Olive (Olea europaea L.) is an evergreen tree traditionally cultivated in the Mediterranean area, relatively tolerant to salinity and drought conditions. However, OLIVE trees are not so resistant to low temperatures. In recent years, because of high demands for OLIVE oil and its fruit, the cultivation of OLIVE trees has been widly spread in Iran. Different cultivars of OLIVEs show diverse reactions to COLD STRESS and so, the selection of cold resistant cultivars is the most effective method to avoid frost damages. In order to compare the impact of COLD STRESS on the content of total PROTEIN, LIPID PEROXIDATION and photosynthetic PIGMENTs, one-years old OLIVE cultivars of Sevillana and Frantoio, were exposed to low temperatures of 10, 5, 0, -5, -10, -15, -20 and the control to 20oC for 12 h. The results indicated that both cultivars were resistant to 0oC temperature with no adverse effects. The photosynthetic PIGMENTs of Frantoio did not change even at -15oC and malondialdehyde levels were slightly increased compared with the control (20oC). Total PROTEIN content in Frantoio showed significant decrease below -10oC, while in Sevillana cultivar there was significant decline of total PROTEIN content from -5oC. Therefore, it could be concluded that the Frantoio cultivar was more resistant to COLD STRESS than Sevillana.
