Abstract
Study was carried out to evaluate the effect of aqueous solution of sulphuric acid in reducing the endocarp/seed coat dormancy of Grewia optiva seeds. Soaking the seeds in dilute sulphuric acid (N/10 H2SO4) for 36 hours was observed to be the most effective method for breaking this type of seed dormancy followed by N/20 H2SO4 for 6 hours under glass house conditions.
