Abstract
Kydia calycina Roxb. is a multipurpose tree species and its wood mainly used in toys industries. Seeds usually 3, kidney- shaped furrowed, dark brown and testa is hard. Regeneration in nature is rare due to its hard-coated seed. Keeping this in view, some suitable method of pretreatment to break the dormancy of seed was evaluated. Germination was enhanced from 18.25%(Untreated) to 64.0% by mechanical scarification. Although this treatment gives early, uniform and highest germination but was a laborious process and hence cannot be employed on large quantity of seed. Therefore, sulphuric acid scarified seeds are recommended.
