Abstract


Proline content is one indicator of plant resistance to salinity stress. This proline content varies based on the level of resistance of each variety. This study aims to determine the variation of leaf proline content from eight rice varieties under salinity stress. This research was carried out in Paluh Merbau, Percut Sei Tuan, Deli Serdang North Sumatra, Indonesia. This research location has saline soil and it was so close to the beach (1 km). This study used a non-factorial randomized block design. There were eight rice varieties tested namely Ciherang (V1), IR 64 (V2), Lambur (V3), Batanghari (V4), Banyuasin (V5), IR 42 (V6), Inpara 10 (V7) and Margasari (V8). The results showed that the leaf proline content of the eight varieties was very varied. Varieties that were resistant to salinity stress tend to have a higher proline content than susceptible varieties. Banyuasin has the highest proline content than the other varieties.
