Abstract
Rice (Oryza sativa L.) has a high sensitivity to salinity stress and it would induce a decrease in the total plant production. Seed priming is strategy to induce the tolerance of salinity stress. In this research used halo priming technique by combining NaCl, CaCl2, KCl, KNO3, and H2O2 to induce salinity tolerance in Cv. Cempo ireng pendek (black rice) and Cv. Merah Kalimantan Selatan (red rice), Pokkali, and IR 64. The experiment was designed in a split plot design with three replications. The treatment details are (i) non-primed (NP) and nonstressed; (ii) non-primed and stressed with 200 mM NaCl solution; (iii) primed (P) and non-stressed, and (iv) primed and stressed with 200 mM NaCl solution for each rice cultivars.
