Abstract

Photosynthetic characteristics of young trees leaves of Black berry were studied with a CO_2 infrared analyzer. The results showed that, the curve of diurnal variation of leaf photosynthesis showed two peaks, appearing at 9:00 and 13:00, respectively. the curve of seasonal variation of Pn. had two peaks, occurring in June and August, respectively. The light compensation point of photosynthesis and light saturation point of leaves were 55 μmol/(m~2·s) and 1 380 μmol/(m~2·s).
