Abstract:
Gleditsia triacanthos L. belongs to family Fabaceae is reported to flourish in urban environments and tolerate wide range of conditions. Seedling production rely upon suitable pre-sowing treatments for seeds with physical dormancy. The present investigation carried to explore different pre-sowing treatments for enhancing seed germination in G. triacanthos was arranged in a completely randomized design with thirteen treatments and three replications. The results indicate that seed dipped in concentrated sulfuric acid for 20 minutes and 30 minutes, followed by soaking in water for 12 h each, increased germination percentage of 84.50% and 83.50% respectively. The study recommends sulfuric acid scarification for hard, impenetrable seed coat with the aim of obtaining the best treatment for breaking dormancy.
