Enzymatic activities of endophyte, SA and endophyte with SA treated plants during drought stress. CAT = catalase; POD = peroxidase; PPO = polyphenol peroxidase. EA = infested with P. resedanum; SA = treated with SA; SA+EA = endophytic fungal associated plants treated with SA. NST, 2-DT, 4-DT and 8-DT represent non-stressed, 2, 4 and 8 days drought stressed plants respectively. The different letter(s) in each stress period showed significant difference (P<0.05) as evaluated by DMRT.
