Seed priming, bengal quince, physiological, bio-chemical and ultra structural changesAbstract
An investigation was carried out to study the physiological, biochemical and ultra structural changes that occur during seed priming in the underutilized medicinal plant Bengal quince. The seeds were soaked in water and GA, solution for 6 h along with control. Among them, seed priming with 100 ppm GA, was scored as the best priming agent for Bengal quince seeds. Evaluation on the causes for the invigorative effect obtained with GA, priming expressed that seed priming with GA, enhanced the physiological performance, biochemical changes viz., amylase and dehydrogenase activity, strengthened the protein profile, enhanced the protein content, improved the gibberellin content of seed and also brought ultra structural changes in embryo as analyzed through scanning electron microscope.
