Abstract

Water deficit is on of the factor that limited growth of plant and oxidative process is a secondary stress due to drought. In order to study the effect of exogenous application of hydrogen peroxide on drought tolerance in ornamental amaranth (Amaranthus tricolor L.) an experiment was conducted in greenhouse conditions. The experiment was factorial based on randomized complete design with 3 replications. Different concentration of hydrogen peroxide (0, 2/5 and 5 mM) and three levels of irrigation regime (after 2 (every 78 h), 5 (every 120 h) and 8 (every 192h) days) were treated in this study. results showed a significant difference in traits measured in different irrigation regimes. with increasing irrigation intervals, CHLOROPHYLL INDEX, shoot and root dry weight, RELATIVE WATER CONTENT (RWC), STOMATA CONDUCTIVITY (gs), plant height and root volume decreased and increased proline, ELECTROLYTE LEAKAGE and ROOT LENGTH. interaction between hydrogen peroxide content and irrigation with different regimes showed that root volume and root weight were significant in 5% level and CHLOROPHYLL INDEX, shoot weight, STOMATA CONDUCTIVITY, plant height, ELECTROLYTE LEAKAGE, free proline and ROOT LENGTH were significant in 1% level. The final results showed that foliar application of hydrogen peroxide can improved alleviate adverse effects of drought stress in ornamental amaranth by increasing proline in 0.5 mM level and increasing CHLOROPHYLL INDEX and shoot dry weight in 2.5 mM level.
