- 摘要:
- 以2种叶用甜菜为试材，采用熏蒸法模拟室内甲醛环境，研究了不同浓度甲醛胁迫对叶用甜菜生理特性的影响，以期为观赏蔬菜的应用提供参考依据。结果表明：叶用甜菜可在0.13 mg?m-3的甲醛环境下生长，该浓度略高于国家居室甲醛含量标准（0.08 mg?m-3）;红叶甜菜的抗甲醛能力强于黄叶甜菜，前者的净化效率及保护酶活性水平高于后者;叶用甜菜的甲醛净化效率随甲醛浓度升高而升高，但增长率会逐渐减缓。
- Abstract:
- Two kinds of leaf beets were used as materials.The effect of different concentrations of formaldehyde stress on leaf beet′s physiological indicators in order to supply references for ornamental vegetables.The results showed that leaf beet could grow up with 0.13 mg?m-3 formaldehyde environment.But this concentration was slightly higher than the national standard of formaldehyde content (0.08 mg?m-3).The ability to fight formaldehyde of red leaves beet was stronger than yellow leaves beet，and the former purification efficiency and activity of protective enzyme were higher than the latter.The efficiency of formaldehyde purification of leaf beet increased with the increase of formaldehyde concentration，but the growth rate was slow gradually.
