نویسندگان Fatemeh Nejadhabibvash

چکیده Hyssop (Hyssopus officinalis L.) as a perennial subshrub of the family Lamiaceae is distributed in the eastern Mediterranean to central Asia. The purpose of this study was to investigate the functions of Se on the phytochemical characteristics in Hyssopus officinalis L. subjected to PEG- induced drought stress. The experimental treatments included three concentrations of Polyethylene glycol (PEG- 6000) 0 %, 2 % PEG and 4 % PEG as the first factor, sodium selenate at three concentrations (0, 20 and 40 mg L-1) as the second factor and their combined effects. The pots filled with perlite and placed in the greenhouse. According to our results, applying Se enhanced the EO content and improved EO quality by increasing hyssop’s main EO constituents. The obtained results proposed that Se promoted the morpho- physio-biochemical features of hyssop plants and supported them for cope on drought stress. Therefore, its use may be recommended under arid and semiarid regions.
