Observation Plant height and chlorophyll a were the most reliable discriminators of barley genotype tolerance.
Observation Relative water content was less predictive of the species than the other traits.
Observation Multivariate stratification separated barley genotypes into tolerant, intermediate and sensitive groups.
Observation HvABF2 gene expression was induced 1.77-fold under drought.
Observation HvSOD1 was moderately upregulated 1.82-fold.
Observation HvAPX1 was upregulated 2.28-fold.
Observation HvP5CS had the strongest response (3.29-fold).
Observation HvP5CS induction did not consistently correlate with tolerance.
Mechanism Sensitive genotypes suffered severe pigment and growth penalties from excessive proline accumulation.
Observation Tolerant genotypes combined growth stability, pigment retention and moderate osmotic adjustment.
Mechanism Drought tolerance in barley at the early growth stage emerged from coordinated regulation of growth, photoprotection and stress-gene activation.
Recommendation The early-stage genotype selection can guide validation under field conditions and breeding.
