e0“For the purpose of evaluating drought resistance of wheat genotypes by identifying germination percentage in osmotic stress solution, -0.50MPa PEG-6000 or -1.00MPa mannitol is ideal, but -0.50MPa PEG-6000 should be preferred if the experiment cost is considered.”

Other claims from this paper (8)
- Intervention effect Sucrose inhibited germinal bud growth through molding and stress.
- Intervention effect PEG-6000 at -0.25MPa inhibited germinal bud elongation.
- Intervention effect Mannitol at -0.50MPa inhibited germinal bud elongation.
- Intervention effect PEG-6000 at -0.50MPa significantly decreased germination percentage.
- Intervention effect Mannitol at -1.00MPa significantly decreased germination percentage.
- Association Germination percentage and germinal bud length decreased as osmotic stress increased.
- Mechanism Osmotic stress slowed water absorption by grains and lowered grain relative water content and osmotic potential relative to water.
- Intervention effect Germination parameters decreased more in PEG-6000 than mannitol at the same osmotic potential.
