The seeds of Clitoria ternatea and Momordica charantia were subjected to seven pre-sowing treatments, i.e., control (T0), peeled coat and soaked in 5 oC for 24 hours (T1), peeled coat and soaked in 37 oC for 24 hours (T2), peeled coat and soaked in 5 oC for 48 hours (T3), peeled coat and soaked in 37 oC for 48 hours (T4), peeled coat and soaked in 5 oC for 48 hours (T5), peeled coat and soaked in 37 oC for 72 hours (T6). The study revealed that peeling the coat and soaking seeds in water for various temperatures and periods improved seed germination. The highest germination and germination energy percentage of C. ternatea were observed in T2, namely 94.95% and 23.69%, respectively, while the lowest germination (0%) and germination energy (0%) was found in T6. The highest germination and germination energy percentage of M. charantia, namely 64.38%, and 16.10%, respectively, were found in T3, while the lowest germination (10.67%) and germination energy (2.17%) were observed in T0. The germination may vary for both seeds used in the study as C. ternatea and M. charantia are different in type. The pre-sowing treatments of seeds would prove its potential in the practical fields.
