Couroupita guianensis Aubl. commonly known as cannonball tree belongs to the Lecythidaceae family are in few numbers in the land of Jharkhand. It is endangered species in many parts of the country. The present study was carried to mitigate the problem by standardizing an efficient protocol for in vitro seed germination. Mature and immature seeds from cannonball like fruits as explants were collected from the site and were soaked in water for one to two days then total and partial decoating and scarification methods employed, sterilized and inoculated to Murashige and Skoog Medium (MS 1962) without any phytohormonal supplementation. The seeds were categorised under six groups based on the age of seeds used for inoculation. The seed groups S3, S4 and S5 showed the sign of germination. The seedlings attained the height of 6 to 7cm.
