| 摘 要： | 目的]研究低温弱光对果菜类蔬菜作物气孔特性的影响。方法]通过比较低温弱光处理组（温度为15℃/8℃,光照为4 000lx）与对照组（温度为25℃/18℃,光照为11 000 lx）,研究番茄、辣椒、茄子、黄瓜、西葫芦、甜瓜气孔相关特性的差异。结果]低温弱光处理后,番茄、辣椒、茄子、黄瓜、西葫芦、甜瓜叶片的气孔开张比和开张度均比CK组大,且差异极显著;气孔导度（Gs）比CK组小,其中处理组茄子、西葫芦、甜瓜叶片的气孔导度与CK组差异显著;胞间CO2浓度（Ci）比CK组大,其中处理组番茄、甜瓜叶片的胞间CO2浓度与CK组差异显著。结论]该研究为果菜类蔬菜作物的高产抗逆栽培提供了理论依据。

| Abstract: | Objective] The research aimed to study the influences of low temperature and poor light on the stoma characteristics of fruit vegetables crops.Method] By comparing the low temperature and poor light group whose temperature was 15 ℃/8 ℃ and illumination was 4 000 lx with the control group whose temperature was 25 ℃/18 ℃ and illumination was 11 000 lx,the difference of stoma characteristics in the tomato,chili,eggplant,cucumber,squash,melon was studied.Result] After the low temperature and poor light treatment,the stomatal opening ratio and the opening degree of tomato,chili,eggplant,cucumber,squash and melon leave were bigger than that in CK group,and the difference was very significant.The stomatal conductance(Gs) in the treatment group was smaller than that in CK group.Gs of eggplant,squash and melon leave in the treatment group had the significant difference with CK group.The intercellular CO2 concentration(Ci) in the treatment group was bigger than that in CK group.Ci of tomato and melon leave in the treatment group had the significant difference with CK group.Conclusion] The research provided the theory basis for the high yielding stress resistance cultivation of fruit vegetables crops. |
