| 摘 要： | 以栽培番茄品种AilsaCraig的6叶期幼苗为试验材料,在水培条件下研究了50,75和100g/LPEG水分胁迫对叶片气孔传导、光合色素含量及发叶速度的影响。结果表明,水分胁迫使气孔传导度和发叶速度降低,光合色素增加。气孔传导度和发叶速度的降低均与水分胁迫强度和持续时间有关,而光合色素的增加主要与胁迫持续时间有关。

| Abstract: | The impact of stomata conductance,photosynthetic pigment content and leaf growth speed on tomato (cv.Ailsa Craig) plant were studied under hydroponic culture with different level of water stress by 50,75 and 100 g/L PEG treatment,respectively.The results showed that both stomata conductance and leaf growth speed were decreased but photosynthetic pigment was increased under water stress.The decrease of stomata conductance and leaf growth speed was closely related to both the strength and the duration of water stress.However,the increase of photosynthetic pigment was mainly related to the duration of water stress. |

| Keywords: | tomato water stress stomata conductance photosynthetic pigment hydroponic culture |
