Germination response to temperature is different among plant seeds. Germination rate and percentage is maximal at optimum temperature (s), and then reach to zero at base and ceiling temperatures. The objective of this research was (1) to evaluate germination response of snail medic seeds to temperature and (2) to determine cardinal temperatures of germination rate and percentage. Therefore, seeds germinated at 10 to 40oC by 5oC interval. Results indicated that response of germination percentage and rate adequately described with dent-like and segmented functions, continually. Base and ceiling temperatures were obtained 0.46 and about 40oC for both germination rate and percentage. Optimum temperatures were 15-27.73oC for germination percentage and 22.22oC for germination rate.
