摘要： Using soil-plant-atmosphere continuum (SPAC) theory and stem volume equation, dynamic changes in stem diameters of apple trees (Malus domestica Borkh. Cv. 'Fuji') were simulated. Numerical simulation results indicate that stem water potential fluctuated sinusoidally and gently on sunny and cloudy days, respectively. Fluctuations in the amplitude and trend were caused by sap flow and storage resistance, respectively. The change in stem-stored water was proportional to the change rate in water potential. Stem diameter increased with fluctuations in clear day; moreover, it varied slightly on cloudy days. Changes in stem diameter were caused by changes in water potential, which was determined by meteorological factors, soil water potential, and characteristics of plants.
