Abstract

The present research attempts to characterize the morphology of seed and evolve effective method to achieve good seed germination percent of Couroupita guianensis under nursery conditions. Experiment was carried out at the nursery of Regional Forest Research Centre, Rajahmundry of AP Forest Department during June to August 2023 with different pre-treatment methods i.e., Normal water, Hot water and Gibberellic acid. A good germination percentage was noticed with pre-treatment of seed with 200 ppm Gibberellic acid for 24 hrs followed by sowing in coconut husk medium under nursery conditions.
