%X With two cucumber varieties (greenhouse variety Jinyou No. 1 and open-field variety Jinyan No. 4) as test materials, this paper measured their net photosynthesis rate (Pn) under given environmental conditions including CO2 concentration, temperature and illumination intensity in phytotron, and the responses of Pn (y) to these factors were modeled by mathematic methods, which could be described as y=exp(-242.1217/x1)61.0202-0.11(x2-30.926)2]exp(-272.8874/x3) 0.9355 for Jinyou No. 1, and y=exp(-179.8803/x1)50.0771-0.0609(x2-34.3455)2]exp(-267.9653/x3) 0.7377 for Jinyan No. 4, where x1, x2 and x3 represented the values of CO2 concentration, temperature, and illumination intensity, respectively. The response of Pn to temperature accorded with conic function, while its responses to CO2 concentration and illumination intensity accorded with exponential function.
