Abstract

By revealing how Quercus aquifolioides responds to phosphorus(P)addition in terms of photosynthetic characteristics,data support for its high-quality and efficient cultivation and germplasm evaluation were provided.With Quercus aquifolioides seedlings of different forest ages as the research object,we set up gradient phosphorus addition treatments and determined the leaf light response curves and photosynthetic parameters using a Li-6800 portable photosynthesis system.Three photosynthetic models were selected to fit the light response curves,and the optimal model suitable for the leaves of Q.aquifolioides was screened out based on the fitting parameters.The differences in photosynthetic parameters of seedlings under different phosphorus addition levels were compared and analyzed to clarify the regulatory effect of phosphorus addition on their photosynthetic characteristics,thereby revealing the response mechanism of photosynthetic characteristics of Q.aquifolioides to phosphorus addition.The results showed that:1)the leaf drifting model performed the best in all groups,with R2>0.98.The values of RSS and MSE were the lowest,and the fitted parameters such as maximum net photosynthetic rate(Pnmax)were closest to the measured values.2)There were significant differences in photosynthetic parameters between different treatment groups.The Pnmax was highest in the one-year low-P addition group,the light saturation point(LSP)was highest in the three-year control group,the apparent quantum efficiency(α)was highest in the one-year control group,and the light compensation point(LCP)was lowest in the three-year low-P addition group.3)Phosphorus addition significantly enhanced the midday depression of photosynthesis in three-year Q.aquifolioides seedlings.Based on comprehensive analysis,the characteristic parameters and fitting effect of the leaf drifting model are superior to those of the other two models,and it can be used as the best fitting model for the light response curve of Q.aquifolioides.The photosynthetic physiology of one-year high-mountain oak seedlings in Sichuan and Yunnan was optimal at a phosphorus addition concentration of 0.5 g per plant.The results provide a scientific basis for the high-quality and efficient cultivation and germplasm evaluation of this species.
