Abstract:
The problem of low germination is due to the hard seed coat in okra can be overcome by seed priming include Hydro priming, Halo priming, Osmo priming and Solid matrix priming. Hydro priming is easy and more economical mode of priming which increases seed germination, reduce germination time and improves root-shoot ratio. Halo priming is performed by dipping seeds in salt solution and it positively affects the germination. Solid matrix priming enhances the salinity tolerance and improves the plant growth. Osmo-conditioning is the process of controlled hydration of seeds which is potentially able to promote rapid and more uniform seed germination and plant growth in okra. The present review highlights priming methods to increase seed germination rate, plant stand establishment and improve seedling vigor for better crop production in okra.
