- Abstract
Transpiration has an important impact not only on the growth of plants, but also on the hydrological cycle.Determining quantificationally the plant transpiration rate helps understanding the hydrological cycle more accurately. The transpiration rate of a single loquat tree at different relative humidity, temperature and illumination intensity was measured in a phytotron chamber with a sap flow system (Dynamax, USA).The effects of the three factors on the transpiration rate of single loquat tree was analyzed by Response Surface Methodology (RSM). The results indicated that the effect of relative humidity, temperature and illumination intensity at given conditions followed the importance order of temperature > illumination intensity > relative humidity. The transpiration rate of single loquat tree is increasing with the accretion of relative humidity and reduction of temperature, but decreasing at the initial stage and subsequently kept constant with the illumination intensity increasing. Through response surface analysis, a model of three factors vs. transpiration rate was acquired and can provide a reference for the calculation of evapotranspiration
