Abstract
A germination study was conducted in College of Forestry, Kerala Agricultural University, Vellanikkara with an objective of finding out the most promising scarification (chemical) pretreatment for four selected tree species of farm/agroforestry importance. Treating the seeds with concentrated sulphuric acid for 5 minutes proved to be the best seed pretreatment in Prosopis cineraria, Paraserianthus falcataria and Leucaena leucocephala in terms of germination, while boiling water treatment for 5 minutes produced superior results in Ceiba pentandra. Days taken for germination did not vary significantly due to various treatments.
