摘　　要：研究了 5种不同浓度的含油废水对秋茄幼苗的叶片叶绿素含量、过氧化氢酶活性、游离脯氨酸含量、含水量、相对电导率与生物量、存活率、茎高生长量等生理生态指标的影响。结果表明 ,50 mg/L和 1 0 0 mg/L浓度组不仅对植株无不良影响 ,而且能促进生长 ;2 0 0 mg/L组植株的某些生理生态指标受到影响 ,但整体上生长正常 ;4 0 0 mg/L和 80 0 mg/L组则对植株各项指标产生显著或极显著影响 ,甚至引起个体死亡。因此 ,在实验室条件下秋茄幼苗对含油废水有一定的耐受性和适应性 。A simulative study with different concentration of oil wastewater showed no harmful effect on Kandelia candel seedlings exposed 50mg/L and 100mg/L oil wastewater,however,this concentration stimulated the growth of seedlings.Treated with 200mg/L oil wastewater,some physiological indexes were affected,but seedlings still maintained normal growth.While treated with 400mg/L and 800mg/L of oil wastewater,almost all the eco physiological indexes were affected significantly or very significantly,and even caused some individuals died.The study indicated that Kandelia candel seedlings could adapt and tolerante a certain extent of oil wastewater.
