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 NaCl 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 .
Key words: NaCl
摘要： 以Hoagland 溶液为基础培养液, 采用沙培法, 研究了0 , 5 , 10 , 20 , 30 mmol􊄯L NaCl 对玉米( Zea mays) 幼苗光合作用的影响。结果表明, 低浓度NaCl (5, 10 mmol/L NaCl ) 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。
