Abstract:
A pot culture experiment using photosynthesis test system was conducted to study the effect of different levels of silicon(Si) supply on the photosynthetic properties and water utilization efficiency in different periods of Paeonia lactiflora Pall..The results showed that no matter what period，the SPAD value，net photosynthesis rate，stomatal conductance and water utilization efficiency of the Paeonia lactiflora Pall.leaves increased firstly，and reached the highest at the level of 60 mg/kg dry matrix，where on the contrary，the transpiration rate changed oppositely.The photosynthetic properties and water utilization efficiency were still better than CK when at the level of 80 mg/kg dry matrix，and no seriously affected were occurred on Paeonia lactiflora Pall.plants.
