Under controlled soil water status, the theoretical water niche of c. smyrnioides was saturate and moderate soil water status ; chuanminshen violaceion was moderate, while a. sylvestri was the most broad, and adapted well from saturation to 20 % water sattus. the photosynthesis of one - year - old and two - year - old c. smyrnioides was higher in saturate and moderate than that of in dry, the recovery of photosynthesis in dry condition was weak when they watered to saturation. the photosynthesis of one - year - old c. violaceum was higher in moderate than in two others ; two - year - old was higher in saturate and moderate than in dry, the former two had little difference
