خلاصه مقاله:
Worldwide, wheat (Triticum aestivum L.) is one the most important agricultural crops both economically and strategically. Because of its relatively good adaptation to different regions of the world with tropical climate and low water irrigation, it is usually considered as more resistant to abiotic stresses than the hexaploid wheat plants. Salicylic acid (SA) is an endogenous growth regulator of phenolic nature and also an important signaling molecule regulates physiological processes in plants such as growth, photosynthesis and some other metabolic processes. Several studies support a major role of SA in modulating the plant response to various abiotic stresses. In addition, it has been found that plants treated with SA generally exhibited better resistance to drought stress. The field experiment was laid out split plot with randomized complete block design with three replications. Treatments included drought stress (I0: control, I1: Irrigation cut in pod stage, I2: Irrigation cut in flowering) as main plot and sub plot consisted of foliar application of salicylic acid (S1: control, S2: 4%Mm, S3: 7%Mm and S4: 1 Mm). Analysis of variance showed that the effect of drought stress and salicylic acid on all characteristics was significant.
