Seed germination of wild Sesamum Radiatum with optimised temperature and chemicals treatment

Sesame is a member of Pedaliaceae family and belongs to the genus Sesamum. They are origin from Africa and comprise of 36 species. These species is generally known as black benniseeds and sesamum. It is cultivated mainly for oilseeds and hold national importance as traditional plant. These plants re...

In this research, two treatment method have been used to improve the seed germination such as water and chemical treatments. In which the water treatment has three categories of (1) soaked in warm water for a few seconds then soaked for 24 hours in room temperature, (2) soaked in hot water for a few seconds and (3) soaked for 24 hours in temperature. Both (1) and (2) categories involved the use of different temperature range from 15°C to 90°C with the increment of 15°C each. Moreover, chemical treatments were also been used involving five types of chemical such as hydrochloric acid (0.2%) solution, sulphuric acid (0.2%) solution, nitric acid (0.2%) solution, gibberellic acid (500 ppm) and thiourea (0.5%) solution. The average growth of chemical treatment was more effective than water treatment. All the chemical treatments showed positive results of seedlings growth.

In the first category of water treatment, the germination capacity increased at minimum temperature and begin to decrease in the germination capacity as the temperature increases. Conversely, the highest germination capacity of second category of water treatment was at maximum temperature of 60°C.
