Abstract：Chlorophyll fluorescence is an effective probe of photosynthesis energy transfer.The maximum quantum yield of the reaction center PS Ⅱ Fv/Fm can effectively reflect the degree of stress.Three ornamental bamboo species,including Phyllostachys aureosulcata f.spectabilis,Ph.aureosulcata f.aureocaulis and Sasa auricoma,were selected to investigate their adaption at Beijing.The annual change in Fv/Fm were tested using Dual-PAM-100 and ImagingPAM-100,respectively,and fluorescence images were then extracted.The results showed that the Fv/Fmvalue in the three bamboo species were the highest in July and then presented a declining trend.The Fv/Fm value of Ph.aureosulcata f.spectabilis fell to the lowest in January,while that of Ph.aureosulcata f.aureocaulis was at the lowest level in February.The Fv/Fm values of both Ph.aureosulcata f.aureocaulis and S.auricoma were higher than the normal value of 0.8 between June and September,while the value of Ph.aureosulcata f.spectabilis was only higher than 0.8 in July.These results indicated that the three ornamental bamboo species grew under stress in most time at Beijing while Ph.aureosulcata f.aureocaulis and S.auricoma were more suitable to grow in Beijing than Ph.aureosulcata f.spectabilis.
