Abstract:
Taking one-yearold ‘Hanfu’ apple and its parents’ variety of ‘Dongguang’ and ‘Fuji’ as test materials,the photosynthetic characteristics were studied by gas exchange method,the changing of Pn and the effect of leaf area,SLW and chlorophyll content on Pn were analyzed.The results showed that there were differences among photosynthetic capacity,carboxylation efficiency (CE),apparent quantum yield (AQY),CO2 compensation points,CO2 saturation points,light compensation points,light saturation points among ‘Hanfu’,‘Dongguang’ and ‘Fuji’.‘Dongguang’ had higher using efficiency to low concentration CO2,low intensity illumination and high intensity illumination,‘Fuji’ had higher using efficiency to high concentration CO2；there were relativity between Pn and leaf area,SLW and chlorophyll content in mature leaves.Fv/Fm of ‘Dongguang’ and ‘Fuji’ were higher than that of ‘Hanfu’.PI of ‘Hanfu’ was higher than that of ‘Dongguang’ and ‘Fuji’.
