Abstract

Today, SEED PRIMING technique has been known as a factor to improve germination and seedling emergence under different environmental stresses. The objective of this research was to evaluate the effect of SEED PRIMING with gibberellic, salicylic acid and water on seed germination of maize seeds under DROUGHT STRESS. Treatments were combinations of 4 levels of DROUGHT STRESS (0, -3, -6 and -9 bar) and 4 levels of SEED PRIMING (25 ppm salicylic acid, 25 ppm gibberellic acid, distilled water and control with no priming) with 3 replications. Results indicated that with increase in DROUGHT STRESS, GERMINATION CHARACTERISTICS such as germination percentage, germination index, normal seedling percentage decreased as mean germination time increased. However, the primed seeds showed better performance compared to non-primed ones. The highest germination percentage (89.3%) was observed in the seeds primed by gibberellic acid. The highest germination index (32.54), normal seedling percentage (85%) and the lowest mean germination time (2.13) were also observed in the seeds primed by gibberellic acid, under control (non-stressed) conditions. Also, SEED PRIMING resulted in an increase in catalase and ascorbic peroxidase activity compared to the control seeds. It is concluded that priming results in improvement in GERMINATION CHARACTERISTICS of maize under DROUGHT STRESS conditions and increases the resistance of maize to DROUGHT STRESS in germination phase.
