Abstract：With the Hibiscus mutabilis under the shade and sun conditions as materials, the photosynthetic physiological characteristics in Hibiscus mutabilis were studied in this paper. The chlorophyll contents, net photosynthetic rate, transpiration rate, stomatal conductance and intercellular CO2 concentration were determined. The results showed that chlorophyll content, specific leaf weight and photosynthetic rate in the middle leaf positions were more than those in two ends leaf positions. The photosynthetic performance of sun Hibiscus mutabilis is superior to that of shade Hibiscus mutabilis. The sun Hibiscus mutabilis is more suitable for cultivated under the strong light intensity condition.
