Other claims from this paper (9)
- Observation The two wheat genotypes differed significantly in ABA, proline, glycine betaine, soluble sugars, reducing sugars, sucrose, and potassium.
- Observation The tolerant wheat genotype had higher ABA, proline, glycine betaine and sugar content than the susceptible genotype.
- Observation The tolerant genotype had higher water content in flag leaves and grains than the susceptible genotype.
- Observation The susceptible genotype contained more glycine betaine and potassium but less ABA and water.
- Intervention effect Proline and glycine betaine increased manifold during water stress.
- Intervention effect Exogenous ABA accelerated osmolyte accumulation in stressed wheat.
- Intervention effect Exogenous ABA improved water status of flag leaves and grains in stressed wheat.
- Intervention effect Exogenous ABA raised grain weight, especially in the susceptible genotype.
- Mechanism The authors suggest that genotype differences in water stress response may be governed by ABA dependent solute accumulation.
