Rates of assimilation and transpiration in Eucalyptus pauciflora Sieb. ex Spreng were measured at various ambient partial pressures of CO(2) and various irradiances and were used to estimate leaf conductance and intercellular partial pressure of CO(2). The responses of leaf conductance and rate of assimilation to change in intercellular partial pressure of CO(2) were expressed in terms of feedback. They are small in the sense that their combined effect was to reduce disturbances in intercellular partial pressure of CO(2) by 30% only. The magnitude of the feedback had no influence on the system as affected by irradiance, because the direct responses of conductance and rate of assimilation to changes in irradiance in the range 0.25 to 2 millieinsteins per meter per second were such that intercellular partial pressure was maintained almost constant.
在不同的环境二氧化碳分压和不同光照条件下，测量了蓝桉 Sieb. ex Spreng 的同化和蒸腾速率，并用于估计叶片导度和细胞间二氧化碳分压。用反馈的方式来表示叶片导度和同化速率对细胞间二氧化碳分压变化的响应。它们的影响很小，其综合作用仅将细胞间二氧化碳分压的干扰降低了 30%。反馈的大小对系统没有影响，因为在 0.25 到 2 毫爱因斯坦/米/秒范围内，导度和同化速率对光照变化的直接响应使得细胞间二氧化碳分压几乎保持恒定。
