在夏季晴天土壤供水充足的条件下，生长在庐山山地上的银杏（ＧｉｎｋｇｏｂｉｌｏｂａＬ．），其向阳叶片蒸腾速率的日变化属午后高峰型，日平均蒸腾速率约为１．８６ｍｍｏｌＨ２Ｏ·ｍ－２·ｓ－１，最大蒸腾速率约为３．８ｍｍｏｌＨ２Ｏ·ｍ－２·ｓ－１；其水分利用率日平均约为２．９ｍｍｏｌＣＯ２·ｍｏｌ－１Ｈ２Ｏ，最高可达８．６ｍｍｏｌＣＯ２·ｍｏｌ－１Ｈ２Ｏ。银杏叶片的蒸腾速率、气孔阻力和水分利用率等对遮荫的响应在一天的不同时间各不相同，表明了银杏的生长对当地变化的光照条件是适应的。气温、光合有效辐射和气孔阻力等因素对银杏蒸腾速率的影响显著。
Under the condition of sufficient water supply in sunny summer, Ginkgo biloba (L.), which grows on the mountain of Lushan, has the highest diurnal variation in transpiration rate of sun-leaf, the average daily transpiration rate is about 1.86mmolH2O · m-2 · s -1, and the maximum transpiration rate was about 3.8mmolH2O · m-2 · s-1. The average daily water use efficiency was about 2.9mmolCO2 · mol-1H2O and up to 8.6mmolCO2 · mol-1H2O. The responses of ginkgo to transpiration rate, stomatal resistance and water use efficiency varied at different times of the day, indicating that the growth of Ginkgo biloba was adaptive to the local illumination conditions. Temperature, photosynthetically active radiation and stomatal resistance and other factors on the transpiration rate of Ginkgo significantly.
