Abstract: A greenhouse experiment was carried out to evaluate the response of six rice ( Oryza sativa L.) cultivars (Ribe, Tri-445, Serhat 92, Kros 424, Baldo and Rocca) to NaCI salinity. While salinity inhibited the growth of all six cultivars, Baldo, Ribe, Rocca and Kros-424 were less affected than the other cultivars. Salt treatment increased Na and CI content of the plants, while it decreased K content. In general, the proline content and stomatal resistance of the cultivars were increased by salt treatment.

Keywords: Salinity, Rice, Proline, Stomatal resistance, Na, K, CI.
