Average values of the maximum quantum yield of the Photosystem II (Fv/Fm) of the species Gigantochloa wrayii (GW), Bambusa oldhamii (BO), Bambusa vulgaris (BVV) by treatment plot (January 2009-February 2010 out of the total 2-year experiment: June 2008-June 2010). Chlorophyll fluorescence parameter Fv/Fm, which is the ratio of variable to maximum fluorescence after dark-adaptation, represents maximum quantum yield of PSII. The parameter has begun to be used for detecting stress in plants. In this study, Fv/Fm distribution pattern was analyzed in plants under various stress conditions in order to obtain basic knowledge for identifying the stress factor.
