Rice (Oryza sativa L.) is the most important cereal crop in the world and it is used as a staple food for over one-third world's population. Salinity is one of the major abiotic stresses, which is reducing the yield of rice crop in the world. The tolerance level of five native non-aromatic, coarse rice cultivars (IR-6, IR-8, DR-82, DR-83 and DR-92) was tested in the current study. A local nursery was established for each cultivar and healthy seedlings were shifted in isolated hydroponic plastic tubs containing the Hoagland solution and 0 (control), 40, 80, 120 and 160 mM of NaCl concentrations. Amongst the five rice cultivars, DR-92 performed better in terms of survival percentage, average plant height, shoot dry weight, percent reduction over control (PROC) for plant height and shoot dry weight, the accumulation of less Na+ and more K+ as well as the higher K+/Na+ ratio in shoot dry matter, than rest of the cultivars at low to high salt-stress (NaCl) conditions. The results show that the non-aromatic rice cultivar DR-92 can survive and give better yield in moderately (40-120 mM NaCl) saline soils. [ABSTRACT FROM AUTHOR] |
