【摘要】 研究不同砧木红星、金冠苹果树枝条、叶片、果实水势日变化 ,结果表明 :各器官水势日变化趋势一致 ,均呈“V”型曲线变化。温度、大气湿度、辐射照度对苹果树水势日变化有显著影响 ,土壤含水量对苹果树枝条水势日变化没有影响。更多还原

【Abstract】 The daily variation of water potential of stem,leaf and fruit of Starking and Golden Delicions apple tree of different stocks can be described abvionsly as curve of “V”.Temperature,relative humidity and irradiance have distinct effect on the daily variation of water potential of apple tree.The daily change of stem water potential of apple tree was not influenced by the soil water content.更多还原
