TAILIEUCHUNG - Salinity resistance of certain rice (Oryza sativa L.) cultivars

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. | Tr.

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. Key Words: Salinity, Rice, Proline, Stomatal resistance, Na, K, CI. Bazı Çeltik (Oryza sativa L.) Çeşitlerinin Tuzluluğa Dayanıklılıkları Özet: Sera denemesi ile altı çeltik (Oryza sativa L.) çeşidinin (Ribe, Tri-445, Serhat 92, Kros-424, Baldo ve Rocca) tuzluluğa dayanıklılıkları araştırılmıştır. Tuzluluk bütün çeşitlerin gelişmelerini azaltmıştır. Bununla birlikte, Baldo, Ribe Rocca ve Kros-424 çeşitleri tuzluluktan diğer çeşitlere göre daha az etkilenmiştir. Bitkilerin Na ve CI içerikleri tuzluluk sonucu artmış, K içerikleri ise azalmıştır. Genel olarak, çeltik çeşitlerinin prolin içerikleri ve stoma dirençleri tuz uygulamalarına bağlı olarak artış göstermiştir. Anahtar Sözcükler: Tuzluluk, Çeltik, Prolin, Stoma direnci, Na, K, CI. Introduction Rice (Oryza sativa L.) is a species native to swamps and fresh water marshes, cultivated varieties of which are among the world’s most important food crops. However, the salinization of some of the areas where it is grown has shown that it to be very sensitive to salinity. Recently there has been great interest in .
