Abstract
The seeds of Pterocarpus santalinus and P. marsupium which have very poor germination rate were treated with different medium to increase the germination percentage. The seeds were soaked in distilled water, different concentrations of H2SO4. HCl and HNO3 and cold treatment at 40C for various time intervals along with a control. The mean pod germination noted after one month. The results that the highest germination percentage was showed by the seeds soaked in 40% HCl for 24 hrs. in the both species. The optimum concentration of acid to soften the seed coat and also to eliminate the growth inhibitors present in the seed coat was found to be 40% HCl.
