Salt treatments
The experiment was conducted in laboratory at the room temperature with 12 h daylight. Every day 5 ml of distilled
water (with or without varying NaCl levels, i.e. 50, 100, 150, 200 and 300 mM) was applied per Petri dish and all
the observations were recorded on the 21st day after germination. The physiological and biochemical studies were
carried under the different salinity levels and all the experiments were carried out in triplicate.
