以温室栽培的苍耳（XanthiumstrumariumL.）为材料，测定了叶片的水蒸气阻力（总扩散阻力减去边界层阻力）、蒸腾速率和叶温。在高（40 ℃白天，35 ℃夜晚）或低（10 ℃白天，5 ℃夜晚）空气温度下预处理72小时的植物。测量是在风洞中进行的，光照强度为1.15 cal cm− 2 min −1，空气温度为5 - 45 C，风速为65 cm sec−1。在5 ~ 25 ℃的叶温下，低温预处理植物的叶电阻（8 ~ 27 sec cm−1）高于对照或高温预处理植物（0.5 ~ 3 sec cm−1）。因此，预处理影响气孔开度。
Leaf resistance for water vapor (total diffusion resistance minus boundary layer resistance), transpiration, and leaf temperature were measured in attached leaves of greenhouse-grownXanthium strumariumL. plants that had been pretreated for 72 hours with high (40 C day, 35 C night), or low (10 C day, 5 C night) air temperatures. Measurements were made in a wind tunnel at light intensity of 1.15 cal cm−2min−1, air temperatures between 5 and 45 C, and wind speed of 65 cm sec−1. Leaf resistances in low temperature pretreated plants were higher (8 to 27 sec cm−1) than in controls or high temperature pretreated plants (0.5 to 3 sec cm−1) at leaf temperatures between 5 and 25 C. Thus, the pretreatment influenced stomatal aperture.
