Adenanthera pavonina is native to Southeast Asia, India, SriLanka, Australia, and is grown widely as an ornamental tree. The seeds possess many traditional medicinal properties and is edible when cooked. The seeds of this tree are orthodox and possess physical dormancy due to hard seed coat. Mechanical removal of seed coat was found to be the most effective in minimising the days taken for germination from 22 days to 3 days. Comparable results could be obtained by treating with 50% HNO3 and H2SO4, where germination occurred within 7 and 6 days respectively. Though mechanical scarification is the best technique for breaking dormancy, it is labour intensive and time consuming. Therefore usage of 50% concentrated respective acids is advisable.
