What does this research mean for the field?

Salinity significantly impairs sorghum germination, growth, and yield, while tolerance is a polygenic trait driven by ion homeostasis and antioxidant capacity that requires integrated breeding and field validation to overcome. Novelty: ClaimNovelty.SYNTHESIS. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Synthesize recent literature (2021–2026) evaluating the physiological, biochemical, and genetic impacts of salinity on Sorghum bicolor to outline breeding and management priorities.

Implication

Systematic review reveals substantial growth and biomass reductions from salinity in Sorghum bicolor, highlighting the necessity of combining genetic selection with targeted agronomic practices.

Key Points

Synthesize recent literature (2021–2026) evaluating the physiological, biochemical, and genetic impacts of salinity on Sorghum bicolor to outline breeding and management priorities.
Identified 160 initial records and screened 118 records after removing duplicates.
Synthesized findings from 44 recent studies assessing sorghum responses across germination, vegetative, and reproductive stages under salt stress.
Saline exposures of 60–200 mM NaCl reduced germination rates by 20–40%, root and shoot elongation by 25–50%, and total biomass by 20–55%.
Tolerant lines retained 40–60% greater biomass, maintained higher K+/Na+ balance, and exhibited two- to five-fold stronger ion homeostasis indicators than sensitive lines.
Stress diminished leaf expansion, photosynthetic gas exchange, panicle fertility, and grain filling, with tolerance mapping polygenically to ion transport, signaling, and osmolyte pathways.
