Abstract:
Four different strains of Cyclamen were used as experimental materials，the effects of light and parameters of different strains of Cyclamen on biological characters，stomatal characteristics and leaf anatomical structure were studied by combining cell biology with photosynthetic physiological parameters，and the correlation analysis of leaf microstructure，biological characters and photosynthetic parameters was carried out,in order to explore the relationship between biological characters and photosynthetic characteristics of different strains of Cyclamen.The results showed that the photosynthetic saturation point of ‘XW-21’ was higher than that of the other three strains，and there were differences in stomatal density and stomatal width under the same leaf area，among which ‘FS-35’ had the highest density of 38 pieces?cm-2.The maximum stomatal width of ‘XW-21’ was 9.4 μm，and the palisade tissue thickness of ‘XW-21’ was 4.23% higher than that of ‘FS-25’ (P<0.05)，and the spongy tissue thickness was only 1.7% higher than that of the latter.Correlation analysis between leaf microstructure and photosynthesis showed that Pn was positively correlated with epidermal thickness，leaf thickness，palisade tissue and spongy tissue.
