This experiment was carried out to investigate the temperature response on the growth behaviour and chemical compositions of the warm-season forage crops, Bermuda grass and Bahia grass, and cool-season forage crops, Italian rye grass and Timothy. The results obtained are as follows; 1) Dry matter yield of each organ of cool-season grasses decreased as temperature rose with an exception of shoot of Timothy, while this temperature response was in the reverse relation with warm-season grasses, Bermuda grass and Bahia grass. 2) Crude protein contents of each organ of Italian rye grass were higher in the high temperature plot than in the low temperature one, while those of Timothy, Bermuda grass and Bahia grass decreased as temperature rose. 3) Total carbohydrate contents of each organ of Italian rye grass and Timothy were higher in the temperature plot of 15℃ than in other temperature plots, 20℃ and 25℃, whereas those of Bermuda grass and Bahia grass were higher in the temperature plot 20℃ than in other temperature plots, 15℃ and 25℃. This trend was shown also in total sugar, reducing sugar and non-reducing sugar contents of all the grasses. 4) The crude starch and hemicellusose contents of all the grasses did not showed a definite tendency. 5) Fructosan contents of each organ of all the grasses decreased as temperature rose, the concentration of fructosan in all the grasses was higher in stubble than in the other plant organs. 6) Lignin contents of each organ of all the grasses increased as temperature rose, and lignin was presented in higher concentration in the root than in the other plant organs.
