Abstract
Present investigation was conducted during Kharif 2017-18 in laboratory, at experimental study Department of Crop Physiology, Narendra Deva University of Agriculture and technology, Kumarganj Faizabad (U.P.). Soil salinity has become a severe threat to ensure food security, salinity-imposed limitations on plant growth. At the present, salinity level stimulates many of the metabolic processes involved in phases (2nd, 4th, 6th, 8th and 10th day) of germination, resulting in an improved performance of germination and higher. Experiment was laid out in complete randomized design (CRD) with three replication on six genotypes of rice crop i.e. tolerant- CSR-36, CSR-43, Usar Dhan-3 and Susceptible- Swarna Sub-1, IR-28, Pusa-44. Present investigation was carried to study the effect of salinity with 0, 50 and 100 mM concentration of NaCl on germination. The exposure of rice varieties to increasing concentration of NaCl had significantly increased germination (%), seed vigour index. It is evident from the result that concentration with NaCl significantly improved the germination and enzymatic activities of rice genotypes. The concentration are effective in increasing the germination percent, Seed vigour index, radicle length, plumule length, and enzymatic activities like α- amylase, catalase and carbohydrates biochemical parameters like proline accumulation, in all varieties under normal as well as under laboratory condition. The concentration with NaCl 0, 50 and 100 mM influences the germination and biochemical changes under normal as well as under anaerobic condition and might be useful in mitigating the adverse effect of laboratory condition or helpful in increasing the yield and yield attributes in all the varieties. Thus, it may be recommended that salinity level with concentration (0, 50 and 100 mM) of NaCl is the most desirable for mitigating the adverse effect of salinity.
