Abstract: Photosynthetic characteristics were carried out with Rubus strigosus Mick.The results indicated:the curve of diumal variation of Rubus strigosus Mick. leaf photosynthesis showed two peaks,appeared ‘Wuxiu’ phenomenon.Pn was positively significantly correlated with Gs,at the same time,the variation of Pn,Gs and Ci was synchronism; the principal environmental factors,which efected Pn,were PFD and RH;the curve of seasonal variation had two peaks; The light compensation point of photosynthesis and light saturation point of Rubus strigosus Mick.1eaves were 750 μmol·m-2·S-1and 21.4 μmol·m-2·S-1, respectively.

Key words: Rubus strigosus Mick., Photosynthesis, Stomata conductance, Intercellular C02 concentration
