Acid rain stress with leaf chlorophyll fluorescence in Pinus massoniana

Abstract: Using a portable PAM-2100 fluorometer,potted plants of Pinus massoniana were used to study chlorophyll fluorescence parameters in different seasons,with three levels of simulated acid rain stress (heavy stress,pH 2.5;moderate stress,pH 4.0;and control pH 5.6). Results showed that maximum efficiency of photosystem II in the dark(Fv /Fm) and potential photochemical efficiency(Fv /Fo)were decreased with increased pH values of acid rain after two years of acid rain spraying. And actual photochemical quantum (yield)also showed the same trend with time. Our results indicated that efficiency of primary conversion of light energy of PSⅡ,the efficiency of potential photosynthetic quantum conversion and the photosynthetic electron transport rate were negatively affected under acid rain stress,which was adverse to plant growth. Thus,P. massoniana is unsuitable for widespread planting in areas of heavy acid rain.[Ch,3 fig. 22 ref.]
