| 摘要 | [Objectives] This study was conducted to enhance the salt tolerance of current rice varieties at the seedling stage and fulfill the urgent requirement for salt-tolerant rice varieties in coastal tidal flats. [Methods] Four high-generation stable rice lines with diverse salt tolerance were employed as test materials, and four NaCl concentration gradients were established for seed soaking treatment. [Results] The seedling survival rate of line 151465 underwent significant alterations after soaking with four different salt concentrations, and the survival rate was the highest after treatment with 1.8% NaCl for 1 d, reaching 65.2%. The average survival rate of other three lines with different salt tolerance reached 62% after soaking with 1.8% NaCl for 1 d, which was significantly higher than those of the 2.2% NaCl and 0% NaCl treatments. [Conclusions] This study provides a basis for reducing the effect of abiotic stress on rice growth and development and improving the utilization rate of saline-alkali land. |
