Abstract

Salicylic acid is involved in plant responses to abiotic stress such as drought, cold, heavy metal poisoning, heat and osmotic stress. This study carried out to investigate the effect of salicylic acid on physiological characteristics of Lolium grass (Lolium perenne cv. “Numan”) under drought stress. A factorial experiment in a completely randomized design with four replications was performed. Lolium perenneThe treatments consisted of three salicylic acid levels (0.0, 0.75, and 1.5 mm) and drought stress consisted three levels (50, 75, and 100 percent of field capacity). Salicylic acid Foliar application at 0.75 and 1.5 mm levels increased the content of chlorophyll a, b and reduced electrolyte leakage, proline accumulation and antioxidant enzyme activity, which suggests that salicylic acid, to reduce the negative impacts of drought stress.
