| 摘 要： | 在实验室条件下,分别以0、0.02、0.20、2.00、5.00、10.00 mg/L 6个质量浓度的邻苯二甲酸二丁酯(DBP)培育红树植物秋茄(Kandelia candel(L.)Druce)幼苗.6个月后对秋茄幼苗的叶绿素含量和抗氧化酶(包括丙二醛(MDA)、过氧化氢酶(CAT)、超氧化物歧化酶(SOD)、过氧化物酶(POD))活性进行分析.研究结果表明:DBP对秋茄幼苗叶绿素含量没有产生不利的影响,相反具有促进作用;随DBP质量浓度的提高,秋茄幼苗叶片MDA含量相应增加,CAT、POD和SOD活性整体呈先上升后下降的趋势.说明,秋茄幼苗能在所设质量浓度的DBP范围内正常生长,对DBP有较强的耐受性和适应性.

| Abstract: | Under laboratory conditions, Kandelia candel seedlings were exposed to six different dibutyl phthalate （DBP） concentrations （0, 0. 02, 0. 2, 2, 5, 10mg/L）. This study evaluated the effect of DBP on malondialdehyde （MDA）, catalase （CAT）, peroxidase （POD）, superoxide dismutase （SOD） activities of Kandelia candel. Results after six months were as follows： the chlorophyll contentand MDA of each treated group showed the inductive effect compared with the control. The CAT, POD and SOD activities increased firstly and then declined with concentration extension. The POD activity, except 10 mg/L group, which was lower than the control, the rest of the groups were higher compared with the control. |
