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.
