'Cara Mia'玫瑰（Rosa hybrida L.）在一系列辐照水平下，在四个叶温下测量叶片净光合速率。与四个叶龄测量，一个非矩形双曲线生理意义的参数被发现，足以代表光合有效辐射（PAR）的反应。最大净光合速率随温度的变化呈凸型，最适温度为30 ~ 37 ℃。PAR补偿和饱和点均随温度的升高而增大。
‘Cara Mia’ rose (Rosa hybrida L.) leaf net photosynthesis rates were measured at four leaf temperatures over a range of irradiance levels. With the four leaf ages measured, a non-rectangular hyperbola with physiologically meaningful parameters was found to adequately represent the photosynthetically active radiation (PAR) responses. Maximal net photosynthetic rates exhibited a convex pattern with temperature with an optimum between 30 and 37C. The PAR compensation and saturation points both increased with temperature.
