- Abstract
Because of its wide consumption, bread wheat is an important cereal grain worldwide in terms of its nutritional and economic properties. However, the quality of wheat is affected by different stresses and environmental conditions. This study was carried out to investigate the effects of the exogenous application, in the early grain-filling stage, of different plant hormones (3-indoleacetic acid [IAA], gibberellic acid [GA3], and 6-benzylaminopurine [6-BAP]) and distilled water as the control on two wheat cultivars (Rijaw and Azar-2). The results showed that interaction effects of plant hormones × genotypes were significant on gluten index, total gluten and falling number. As well, grain-filling duration was affected by plant hormone and genotype. However, hectoliter weight was affected only by genotype. There was a positive relationship between gluten index and grain-filling duration in both years of the experiment. Overall, the application of plant hormones can increase wheat grainfilling duration under dry-land conditions, leading to increases in total gluten and gluten index.
