| 摘 要： | 以Hoagland溶液为基础培养液，采用沙培法，研究了0，5，10，20，30mmol／LNaCl对玉米（Zeamays）幼苗光合作用的影响。结果表明，低浓度NaCl（5，10mmol／LNaCl）处理使其叶绿素含量增加，Chla／Chlb增大，PEPCase活性提高，光合速率增强。说明低盐促进玉米的光合作用可能与叶绿素含量增加，Chla／Chlb增大以及PEPCase活性提高有关。

| Abstract: | Seedlings of Zea mays cultured with Hoagland nutrient solutions were treated with different low levels of NaCl （0, 5, 10, 20, 30 mmol/L）. After 30 days treatment, several physiological paramaters were determined, including the content of chlorophyll, the Chla/Chlb ratio, the activity of PEPCase and the photosynthetic rate （Pn）. The results showed that the content of chlorophyll, the Chla/Chlb ratio, the photosynthetic rate and the activity of PEPCase increased under low NaCI level （5, 10 mmol/L）. It could be concluded that the rise in photosynthesis of Zea mays seedlings under low NaCl level might be related to those changes in the physiological parameters above. |
