Other claims from this paper (17)
- Intervention effect Drought reduced relative water content by 1.3% to 3.2% in barley.
- Intervention effect Drought reduced plant height by 14.7% to 29.6% in barley.
- Intervention effect Drought reduced dry biomass by 2.3% to 24.9% in barley.
- Intervention effect Drought strongly increased proline accumulation by 23.6% to 454% in barley.
- Intervention effect Drought decreased chlorophyll a by 10.1% to 79.5% in barley.
- Intervention effect Drought decreased carotenoids by 6.2% to 70.9% in barley.
- 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).
- 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.
