Abstract:
Taking needle reddening and healthy Pine of Arden Botanic Gardens，Jinlin Park and Welcome Avenue in Baotou City as material，the effect of outdoor photosynthesis rate of needle reddening and healthy P.tabulaeformis were compared and studied.The results showed that the law of P.tabulaeformis photosynthesis rate showed a bimodal.The photosynthesis rate of P.tabulaeformis which in different growth conditions in the same place was significantly different，the peak photosynthesis rate of healthy and needle reddening P.tabulaeformis was 13.80 μmol? m-2?s-1,11.60 μmol?m-2?s-1 respectively.There must be relationship between the same growth condition P.tabulaeformis which grew in different plots.Furthermore，the rate of photosynthesis of the same P.tabulaeformis at different months during the year indicated single peak along with the light intensity variation.
