Effect of oil wastewater on some eco-physiological indexes of Kandelia candel seedlings
含油废水对秋茄幼苗的几个生理生态指标的影响

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.
