Under normal conditions, low production of okra plants is due to uneven and slow germination of seeds. As the little information is available regarding the special effects of priming to increase the germination of okra seeds under normal conditions. Therefore with this interpretation, a lab experiment was performed to find out the effects of priming with various concentrations of PEG (a potential priming agent) along with soaking durations and distill wateron the germination, emergence, plant lengths and weights and seedling growth. Seeds of okra were pre-soaked in 4%, 8%, PEG solutions and distill water for 12 and 24 hrs. Results of the study showed that priming enhanced seeds germination, dry and fresh weight of seedlings, length of plants, number of leaves and seedling growth. All the characters showed the best results when wheat seeds treated with 8% PEG solution compared to nonprime and hydro primed seeds. Hydropriming also enhanced these parameters as compared to controls. Soaking durations were also found to be evident because optimal results were obtained after 24hrs of soaking in all treatments. Therefore it is suggested that seed priming had important role to improve the overall seedling growth as well as germination of seeds.
