Cassia alata L. is an outstanding plant of Chhattisgarh in India. different parts of the plant such as leaves, stem, root and seeds have medicinal properties. The study investigated the effect of light and temperature on scarified seed of Cassia alata on the germination percentage because seeds are the main source of perpetuation in Cassia alata. Seeds have a wide range of adaptation capacity to survive in the adverse environmental conditions in the higher plants. Six months old seeds are incubated at 15?,20?,25?,30?,35?,40? and 45? which is coupled with acid scarification and mechanical scarification. (Seeds did not germinate without scarification.). In this study maximum percentage of germination was obtained between 25? to 30?. Seed germination was observed from 3rd day up to 7th day. Maximum germination percentage in the direct light was 85% at the temperature of 300c and minimum percentage was 23% at the temperature of 40?. At 45? no germination has been occurred. In diffused light condition, maximum germination percentage was 93.75% at 30?, and minimum percentage was 45.75% at the temperature of 40?. In dark, maximum germination percentage was 86.25% at the temperature of 30? to 35?, and minimum germination percentage was 33.75% at 40?. The length of dormancy was studied by continuous observation of collected seeds up to 6 months. Seeds were collected in January 2024, and germination occurred in August 2024. Six months old seeds show 80-95% germination at 25? to 30?.
