The effects of heavy metal Pb stress on the physiological and biochemical properties of leaf in six two-year old green trees were studied with pot experiments.The results showed that with the increasement of lead concentration,the SOD,POD,CAT activities increased in the beginning and then falled rapidly,while the relative conductivity rate increased all the time.Anti Pb stress abilities are Oriental arborvitaeKoelreuteria paniculataForsythia suspensa)Berberisthunbergiicv atropurpureaJasminum nudiflorumCornus alba.The anti stress abilities of Forsythia suspensa and Koelreuteria paniculata are better than Jasminum nudiflorum and Berberisthunbergiicv.atropurpurea, and significantly better than Cornus alba.But the anti difference ability of Koelreuteria paniculata and Forsythia suspensa is not significant,so is that of Jasminum nudiflorum Lindl and Berberisthunbergiicv atropurpurea.
