Abstract
The study was to determine the effect of trehalose treatment on growth, hydrogen peroxide and antioxidant enzymes in tomato plants growing under drought stress. In an experiment, the seeds were transferred to plastic pots, and the pots were divided into four groups. , the first and second groups without treatment 90%, 20% WHC (Water Holding Capacity)), while the third and fourth groups, 90%, 20% WHC In the presence of 25 mM trehalose (Tre). On day 30, plants were harvested, growth parameters, hydrogen peroxide (H2O2) and enzymes measured. Drought stress caused significant growth inhibition including fresh and dry weight, root length and shoot height. There was an increase in hydrogen peroxide and also an increase in the activity of some enzymatic antioxidants (SOD, CAT, and PPO) and a decrease of others (APx, GR, and GHPx) in the roots and stems of drought-stressed plants. Treatment with 25 mM trehalose significantly improved growth parameters compared to drought-stressed plants, and the results in this study showed a decrease in the activity of hydrogen peroxide (H2O2) and an increase in the activities of SOD, CAT, APx, GSHPx, GPx and PPO in the treated plants.
