The results showed that root colonization by <em>F. mosseae</em> and <em>P. occultum </em>was significantly decreased by 7-week soil drought treatment. Under drought stress conditions, mycorrhizal fungal treatment considerably stimulated root total length, surface area and volume, as compared with non-mycorrhizal controls. In addition, inoculation with arbuscular mycorrhizal fungi also increased leaf relative water content and accelerated the accumulation of root glucose and fructose under drought stress. Mycorrhizal plants under drought stress registered higher activities of superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD) and ABA levels in roots, while lower MDA contents, relative to non-mycorrhizal plants. As a result, mycorrhiza-inoculated plants represented better physiological activities (e.g. antioxidant defense systems, root morphology, and sugar accumulation) than non-inoculated plants in response to soil drought, whilst <em>P. occultum</em> had superior effects than <em>F. mosseae</em>.</p>}, number={1}, journal={Notulae Botanicae Horti Agrobotanici Cluj-Napoca}, author={LIANG, Sheng-Min and JIANG, Dao-Ju and XIE, Miao-Miao and ZOU, Ying-Ning and WU, Qiang-Sheng and KUČA, Kamil}, year={2021}, month={Mar.}, pages={12209} }
