Other claims from this paper (15)
- Intervention effect Foliar SeNPs improved wheat seedling growth and morphophysiological and biochemical responses.
- Intervention effect Foliar SeNPs improved expression of wheat stress-responsive genes.
- Intervention effect Drought had a greater detrimental impact on wheat than heat.
- Intervention effect Heat significantly affected expression of stress-responsive genes in wheat.
- Observation Drought and heat responses varied among wheat genotypes.
- Intervention effect SeNP spraying improved wheat transpiration rate.
- Mechanism SeNPs increased antioxidant enzyme activity and stress-responsive gene expression, which the authors linked to enhanced drought and heat tolerance.
- Intervention effect SeNPs enhanced SOD activity across all wheat genotypes compared with control.
- Observation Sids-12 had the highest SOD activity at 196.43 U·mg−1 FW·min−1.
- Observation Giza-168 had the lowest SOD activity at 152.30 U·mg−1 FW·min−1.
- Observation Stress-responsive gene expression was more significant in tolerant Giza-171 and Giza-168 than sensitive Misr-1 and Misr-3.
- Association Under stress, fresh weights, photosynthetic pigment content, stomatal conductance, and transpiration rate correlated positively with plant height.
- Association Under stress, root and shoot dry weights, MDA, proline, H2O2, and APX correlated negatively with plant height.
- Observation Giza-168, Giza-171, Sids-12, and Sids-14 performed well in both stress conditions and were classified as tolerant.
- Recommendation The authors propose using the tolerant genotypes in future breeding for climate change.
