Abstract:
Abstract:18 Xinjing wild apple clones which were selected from 600 clones of Tianshan area were used as materials to measure the changing of photosynthesis rate(Pn ) and chlorophyll fluorescence in different month by Li-6400XT and Porket PEA.The results showed that,the dominant factors affecting the photosynthetic were different,the dominant factor was Gs in June while in July and August the dominant factor was both Ci .In September Tr and Gs were turned into the dominant factor.There was no obvious difference on the influence of photosynthesis from Tr ,Gs and Ci in October.The dynamic change of chlorophyll fluorescence showed that, Fo , Fm , Tfm , DIO/ CSO, RC / CSO, PIcs and Area were all reached significant correlation level with Pn and photochemical reaction had great influence to Pn .Photosynthetic rate was not significant difference among different months.There was a significant difference between clones,the annual average photosynthetic rate of No.1 was significantly higher than other clones.
