Abstract

Priming has a long and chequered history dating back to time of Greeks. Seed priming has shown promise in enabling seeds to overcome biotic and abiotic stresses. Simple priming techniques using salt solutions gave way to elaborate and sophisticated media that warrant close monitoring. Biopriming of late has been practiced for making priming eco-friendly. Elucidation of molecular basis has shown the cause for invigoration but confirmation of DNA's role is yet to be done. Activation of preformed enzymes in providing vigor seems putative. Development of tests to determine primed seed quality is urgently warranted. Addressed in the paper are the ways and means for assessing the quality of primed seeds. Methods to store them for long periods are necessary conserve the benefits and market primed seeds to promote their use over time and space.

Keywords: Seed primimg, bioprimimg, priming techniques, advantages, disadvantages.
