Physiological and antioxidant responses of marjoram (Origanum Majorana L.) under drought stress mediated by Salicylic acid and mycorrhizal symbiosis.

ABSTRACT: Drought stress, exacerbated by climate change, is a major limiting factor for herbs cultivation. This study aimed to evaluate the combined effects of salicylic acid (SA) and mycorrhizal fungi (MF) on marjoram under drought stress conditions. The experiment was conducted over two years (2022-2023) using a split factorial design within a randomized complete block with three replications. The study's primary factor was drought stress at three levels: 90% (D0), 70% (D1), and 35% (D2) of field capacity (FC). The secondary factor included two sub-factors: SA concentrations (0, 100, and 300 mg L^-1) and MF inoculation (non-inoculated (M0) and inoculated with Glomus hoi (M1)). Results demonstrated that drought stress decreased relative water content (RWC) (46.8%), chlorophyll content (35
