Abstract

Abstract: In order to provide an evidence for guiding artificial planting of P. pedatisecta, the light-response curves and diurnal photosynthesis (Pn) of mature leaves were measured with LI-6400 system. The results showed that the critical points of light saturation and light compensation (LCP), apparent quantum yield (AQY) of P. pedatisecta was 1000 μmol/(m²·s), 18.44 μmol/(m²·s) and 0.0318 respectively. The lower LCP indicated that P. pedatisecta was a shade-loving plant. The curve of diurnal variation of net photosynthetic rate of leaves of P. pedatisecta had two peaks, and there was a significant ‘midday depression’ at noon. Correlation analysis showed that the Pn was correlated significantly with Tr and PAR, with the correlation coefficient of 0.721 and 0.718 respectively. The P. pedatisecta was a shade-loving plant, therefore, it was suggested that intercropping of P. pedatisecta with tall crops, such as maize, wheat, sorghum and rape, could get shadowy environment, decrease midday depression of photosynthesis. Another way to decrease midday depression of photosynthesis was reasonable irrigation for maintaining the relative humidity of the environment. The light saturated point of P. pedatisecta was 1000 μmol/(m²·s), so the light intensity of the shadowy environment could not be lower than 1000 μmol/(m²·s).
