Abstract:
Taking 6 indigenous yam varieties in the west of Shandong province，that were ‘Mingdoizi’,‘Xishizhongzi’,‘Jipicao’,‘Dabaiyu’,‘Daheyu’,‘Jiujinhuang’ as materials，net photosynthetic rate (Pn)，transpiration rate (Tr)，stomatal conductance (Gs) and intercellular carbon dioxide concentration (Ci) were determined.Then the daily variation trend of Pn and Tr，the correlation between Pn and Tr，Gs，Ci were analyzed.The results showed that the daily variation trend of Tr manifested as a single-peak curve，with the peak value at 14:00.But that of Pn manifested as a typical double-peak curve，and the first peak appeared at about 10:00，the second at about 14:00.In the variation curve，a obvious ‘Midday depression’phenomenon could be observed.Through correlation analysis，it found that there was a significant positive correlation between Pn and Gs，but a significant negative correlation between Pn and Ci in the three varieties of ‘Xishizhongzi’，‘Dabaiyu’and ‘Daheyu’.Meanwhile，the Pn of ‘Mingdouzi’ had an extremely positive correlation with Gs，and the Pn of ‘Jipizao’ had positive correlation with Tr.
