Abstract
Drought is one of the most common abiotic stresses, affecting the growth and productivity of crop plants globally, particularly in arid and semi-arid regions. Different strategies are used to mitigate the impact of drought among crop plants. Exogenous application of different substances are known to decrease the effects of various abiotic stresses, including drought stress. The aim of this study was to evaluate the effect of Ca2+ and H2O2 in developing drought stress tolerance in Brassica napus “Bulbul-98” seedlings. Brassica napus “Bulbul-98” seedlings were exposed to 5, 10 and 15 mM Ca2+ and 2, 5 and 10 μM H2O2 concentrations twice at an interval of two days for up to 20 days after germination. Drought stress decreased relative water content…
