Abstract: In this study,the photosynthesis intensity of five tested wood plants is decreased but no injured symtoms are found when treated with 20 ppm of CdCl2 or 500 ppm of Pb(NO3)2.The decrease of photosynthesis intensity of wood plants polluted by Cd and Pb is related to their tolerance towards heavy metals,which is increased in the order:Persica davidiana,Ailanthusaltissima<Syringa oblata,Fraxinus rhynchophylla<Elaeagnus angustifolia.The influence of CdCl2 is larger than that of Pb(NO3)2
