To investigate the effectiveness of selenium (Se) and Se nanoparticles
(Se-NPs) in improving biochemical and physiological characteristics
of savoury in drought stress conditions, a factorial experiment
based on the completely randomised design with three replications
was used. Results demonstrate that Se-NPs considerably
enhanced several biochemical parameters, such as relative water
content (RWC), antioxidant enzymes activity, and total soluble protein
in drought and normal conditions. At the stress level from 100
to 40% of field capacity, a gradual decrease in chlorophyll and
CARs contents was observed and under stress and normal conditions,
the application of Se-NPs (10 mg L−1) led to an increase in
the content of pigments. Total soluble protein, total phenolic and
flavonoid contents showed significant increases in plants treated
with Se-NPs under drought stress. Generally, the use of Se-NPs in
drought stress conditions can be effective in improving the growth,
biochemical, and physiological characteristics of savoury.
