Title: Preliminary study on photosynthetic characteristics of walnut
Abstract: The photosynthetic and stomatal characteristics of walnut were comparatively studied between spur type cultivar'Pu 50'and common cultivar 'Luguang'with photosynthesis analyser CIRAS-1. The curves of diurnal variation of net photosynthesis rates (Pn) were twin-peaked, occurring at 11:00 and 15:00, with peak value being 15.7 and 14.0 μmol·m -2 ·s -1 , respectively. The light saturation point for Pn in both cultivars was 1400 μmol·m -2 ·s -1 . The light compensation of 'Pu 50'was 60 μmol·m -2 ·s -1 , whereas that of 'Luguang' was 100 μmol·m -2 ·s -1 , which could be serve as a guide to determine the planting density and foliage density.
