The photosynthetic leaf characteristics of two rose species native to Japan were measured. The optimum temperature range for photosynthesis of Rosa bracteata was higher than that of Rosa rugosa. The photosynthetic response to temperature of R. bracteata was slower than that of R. rugosa. Maximum photosynthetic rates were reached at an irradiance of higher than 750 m mol mÿ2 sÿ1 in both species....
