Salinity is a major environmental challenge that hampers agricultural sustainability by affecting vast expanses of arable land globally, including significant portions of the Songnen Plain, which hosts substantial areas of saline-sodic soil detrimental to most plant life. This study focuses on Salix linearistipularis, a naturally salt-tolerant woody plant endemic to the region, to explore its potential in ecological restoration and soil improvement. Through extensive laboratory experiments, we employed various plant tissue culture methods to ascertain the most effective techniques for regenerating Salix linearistipularis, thereby facilitating its use in combating soil salinization. The research utilized several culture media and hormonal treatments to determine optimal conditions for seed germination, callus induction, and subsequent plant regeneration. Key findings indicate that specific combinations of growth hormones significantly enhance the rate of callus formation and adventitious bud differentiation, essential for the plants survival and growth in saline conditions. Furthermore, the study demonstrates the potential for these methods to produce genetically stable plants capable of thriving in hostile environments. The findings provide a valuable foundation for future applications in ecological restoration projects aimed at mitigating soil salinity issues.
