Effects of endophyte P. resedanum association on the shoot length, chlorophyll content and shoot biomass recovery in various treatments after exposure to osmotic stress. The control plants were treated with distilled water. EA plants were infected with P. resedanum; SA plants treated with 10-6 M SA, while SA+EA plants had endophytic-fungal association and treated with SA. 2-DT, 4-DT and 8-DT represent the osmotic stress induced by PEG for 2, 4 and 8 days respectively; NST (not stressed treatment). The different letter (s) in each treatment showed significant difference (P<0.05) as evaluated by DMRT.
