| 摘 要： | 以宁杞1号苗为试验材料，采用开顶式气室控制CO2浓度，研究大气CO2浓度倍增后CO2对宁夏枸杞不同器官中糖分积累的影响。结果表明，CO2浓度倍增处理显著降低了叶片中果糖、淀粉的含量以及果实中蔗糖的含量，提高了果实中淀粉的含量；但对枸杞茎和根中的各种糖分的含量无显著性影响。

| Abstract: | Taking Lycium barbarum seedling as research material,and using open-top chamber to control CO2 concentration,we studied the changes of sugar content in different organs of L.barbarum to analyze the sugar accumulation under doubled atmospheric CO2 concentrations.The results followed that doubled atmospheric CO2 concentration had no significant effect on the sugar content in the seedling stem and root,but the treatment reduced the fructose content in leaf,starch and sucrose contents in fruit significantly.Moreover,the treatment increased the content of fruit starch significantly. |
