Chlorophyll fluorescence of Carya cathayensis with simulated acid rain

    Corresponding author: YU Shu-quan

Abstract: What’s the effect of acid rain on Carya cathayensis,an excellent dry fruit tree plant which mainly produced in Zhejiang. The chlorophyll fluorescence analysis was used to determine the effects of acid rain stress with C. cathayensis. The experiment was set up with four groups of simulated acid rain treatments,including pH 2.5,pH 3.5,pH 4.5,and pH 5.6 (as the control) in Oct. 2006,Apr. 2007,July 2007,and Oct. 2007 with 10 pots of one-year-old C. cathayensis for each treatment. Results showed that as pH of the simulated acid rain decreased,maximal photochemical efficiency of PhotosystemⅡ(PSⅡ)(Fv /Fm),potential activity of PSⅡ(Fv /F0),actual photochemical efficiency of PSⅡ(ΦPSⅡ),and chlorophyll content were all decreased and they were not obviously different except in Oct. 2007(P<0.01). All test parameters could be used as the physiological indexes for assessment parameters of acid rain resistance. C. cathayensis was more susceptible to low temperature. [Ch,2 fig. 2 tab. 25 ref.]
