The results showed that there were differences between adaption and regulation of different wheat varieties by prophyl dihydro jasmonate, so as to show diversity of gas exchange parameters, such as photosynthesis, water usage, etc. There was no evident difference between the reaction of two spring wheats (Jinchun1 and 1608) and the winter wheat (Xiaoyan 22) to PDJ. Different parameters of different wheat varieties had inequable reaction to different concentration of PDJ. Photosynthesis rate, water use efficiency and stomatal limiting value were enhanced when PDJ concentration reached a high degree. At the same time, leaf transpiration rate and stomatal conductance decreased. Therefore, wheat could maintain normal physiological activities while environmental conditions were changed.

结果发现，面对类似激素双氢茉莉酸丙酯调控下的不同品种小麦适应与调节存在差异，从而导致光合和水分利用等气体交换参数的表现也存在差异；两种春小麦（金春1号、l608）和一种冬小麦（小偃22）之间对PDJ的反应没有明显的冬春性间的差别；对不同品种、不同参数，PDJ起到作用的浓度不同，但无论如何PDJ都有相同的作用，当这种激素达到一定的浓度后，就会增强小麦的光合速率和水分利用率，增加气孔限制值，降低叶片的蒸腾速率和气孔导度，从而在外界条件变化时保持体内水分、延缓气孔关闭，维持体内正常的生理活动。

The initial rate V0 was influenced by the ratio of molar concentration for butanol to hexanoic acid C(superscript 0 subscript ROH)/C(superscript 0 subscript HA)(at a range of 0.2-17). As C(superscript 0 subscript ROH)/C(superscript 0 subscript HA) decreases, especially when C(superscript 0 subscript ROH)/C(superscript 0 subscript HA), the V0 increases rapidly.

反应初始速率V0与正丁醇和正己酸摩尔浓度的比值C(上标 0 下标 ROH/C(上标 0 下标 HA)有关，在C(上标 0 ROH)/C(上标 0 下标 HA)=0.2-17范围内，随C(上标 0 下标 ROH)/C(上标 0 下标 HA)比值减小，初始速率V0增大，尤其是当C(上标 0 下标 ROH)/C(上标 0 下标 HA)时，V0迅速增大。
