Popis:	Common beau (Phaseolus vulgaris L.) is grown over a wide range of environments, including sites with low or high soil temperatures at sowing time. To describe the temperature response of seed germination, 20 bean genotypes were evaluated using a rolled paper towel system with 11 constant temperatures ranging from 12 to 34 o C. Germination response was characterized by fitting cumulative counts using a maximum-likelihood analysis. Rate of germination increased from a base temperature (T b ) typically near 8 o C to an optimal development temperature (T o ) of 29 to 34 o C. T b did not differ among common bean genotypes
