Comparisons of the Chlorophyll Fluorescence Parameters in Different Camellia oleifera Varieties
The chlorophyll fluorescence parameters of leaves of Camellia oleifera of different cultivars were studied by the chlorophyll fluorescence measuring technique.The results showed that the maximal photochemical efficiency of photosystem ΙΙ(Fv/Fm),apparent photosynthetic electron transport rate(ETR)and the minimal saturation intensity of Camellia gigantocarpa were the maximum among the three tested varieties.The results mentioned above indicated that C.gigantocarpa could grow quickly and had potential physiological and biochemical foundations to obtain high biomass.The issue was confirmed by light response curves and initial slopes from response of ETR to light intensities in different Camellia oleifera cultivar leaves.
