Abstract: In order to obtain for screening and utilization of high photosynthetic efficiency genotype of photosynthetic efficiency of Chinese prickly ash varieties,seeking the best management mode,improve the quality of Chinese prickly ash.In the fields,used the Li-6400XT photosynthetic apparatus to measure and analyzed eight different origin 4 years Chinese prickly ash trees for photosynthetic physiological characteristics.The results showed that the instantaneous net photosynthetic rateis as follows:Dangcunwuci > Shizitou > Qinanyihao > Wududahongpao > Wucihuajiao > Fuguhuajiao > Hanchengdahongpao > Fengxiandahongpao.The diurnal variation curves of net photosynthetic rate (Pn) of eight Chinese prickly ash in different producing areas were different, which showed two types,single peak curve and double peak curve.Correlation analysis showed that Chinese prickly ash leaf net photosynthetic rate and transpiration rate,cond,water use efficiency had a significant or highly significant positive correlation,leaf net photosynthetic rate and the Ci had a highly significant negative correlation (P<0.01).Though light response curves of Chinese prickly ash light compensation point of the range of 36.30-102.76 μmol/(m2·s),and light saturation point range from 332.41 to 467.89 μmol/(m2·s). and the CO2 response curves of Chinese prickly ash CO2 compensation point of the range of 47.46-76.41 μmol/(m2·s),and CO2 saturation point range from 698.887 to 1 509.000 μmol/(m2·s). The experimental results can provide reference for later cultivation and management of Chinese prickly ash.

Key words: Chinese prickly ash, Photosynthesis, Net photosynthesis rate, Transpiration rate, Stomatal conductance
