Résumé
In a greenhouse experiment, the effects of two levels of drought (25% and 50% of field capacity, FC) and the control (75% FC) on growth, some physiological processes, and the contents of some secondary metabolites in wheat (Triticum aestivum, cv. Masr 2) at seedling (30 days), vegetative (65 days) and yield (160 days) stages, were studied. The ameliorative effects of the foliar spray for the harmful effects of drought by the bio-stimulant yeast extract (10%) or the chemical fertilizer lithovit (3.8%) were also studied. The results showed that both levels of drought stress decreased all of the measured growth criteria of wheat (shoot height, root length, shoot and root fresh and dry weights and leaf area) at both FC at the three growth stages.
