Caesalpinia pulcherrima (L.) Swartz (family Caesalpiniaceae) is introduced and cultivated in Pakistan as an ornamental plant. It has medicinal values as well. Laboratory studies revealed that whole of seeds did not germinate up to 60 days with any of the treatment. At control seeds germinated 40%, while 60% and 70% at presoaking for 12 and 24 hours respectively. 40% germination occurred at one hour acid treatment and no germination at three hours acid soaking and combination of acid and water. Mechanical scarification and 12 hours water soaking showed best results with 80% germination. There were no satisfactory results with mechanical scarification and chemical scarification combination. Similarly, mechanical scarification, chemical scarification and water combination gave poor results.
Keywords: Ecophysiology, Caesalpinia pulcherrima germination, Water soaking, Sulphuric acid, Mechanical scarification and 12 hours water soaking 80% germination.
