Abstract
Two field experiments were conducted at Agricultural Experimental Station Research Centre of National Research Centre, Nubaria, El-Bahira Governorate, Egypt during two successive seasons 2017/2018 and 2018/2019. Each experiment was arranged in split- split plot design with four replicates. The present study investigated the effect of arginine (Ar) as amino acid priming agent, applied as foliar application spray, on growth, yield and its components, some chemical constituents of yielded grains of two wheat (Triticum aestivum L.,) cv., Gemiza-9 and Misr-2 underdrought. Moreover, the study aims to determine suitable concentrations of (Ar) as exogenous treatment to enhancewheat tolerance to drought. Foliar application spray with three levels of arginine (0, 2 and 4 mM/L) were applied twice after 50 and 60 days from sowing to increase the tolerance drought of wheat cultivars which irrigated with four treatments from water stress (Normal irrigation as a control, Once irrigation at tillering, germination and ripeningstages) on two wheat cultivars (Gemiza-9 and Misr-2). The obtained results clearly indicated the role of Ar increasing the tolerance of wheat plants to drought. The highest rates of arginine led to significant increase in growth, yield and its components as well as chemical constituents of the wheat grains in both growing seasons. The magnitude of increments was pronounced in response to wheat culivar Misr-2 and 4 mM/L ofarginine as a foliar spray which led to positive changes in all studied parameters under normal irrigation. All treatmentswere effective in alleviating the harmful effect of drought.
