Abstract: Leaves of Pleioblastus fortunei,an ornamental bamboo species,were sprayed with simulated acid rain（SAR） with different levels of pH（4.0,3.0,2.0） to study the effects of SAR on leaf physiological characteristics.The SAR with different intensity could result in damage symptoms appeared on the leaves.The lower the pH value was,the severer the damage was.During the early stage of stress relief,the values of Pr and SPAD were below to control and MDA,MP,SOD and POD were higher than control,whose ranges of the change increased significantly as the stress became deeper.Pr,MDA and MP could play as an important basis reflecting the damage degrees under SAR stress because of the sensitivities to stress.After one month recovery,the most of indexes of pH of 4.0 could return to control.pH of 3.0 could recover but not obviously.All the indexes of pH of 2.0 could not return to control and with significant differences（P ＜ 0.05）.P.fortunei can adapt to pH of 4.0 SAR stress and stand pH of 3.0 SAR in a certain degree,but suffers irreversible damage during pH of 2.0 SAR,which is agree with morphological observation.Under high frequent pH of 2.0 SAR,the leaf damage of P.fortunei may be resulted directly from the accumulation of excessive H+.However,the physiological damage and repair produced by pH of 4.0 SAR is related to the regulation of reactive oxygen species metabolism.
