Abstract: In order to examine the differences in growth and light utilization among Aleurites montana provenances,the study was conducted at A.montana breeding center of Zhangdun Forestry Station,Jianyang District,Nanping,Fujian Province in 2019,where 14 different provenances of 1 a A.montana seedlings were planted in a common garden.The growth parameters of seedlings were measured,including height,ground diameter,biomass and seedling performance index,and physiological traits of seedlings were determined,such as gas exchange parameters,fluorescence parameters and chlorophyll contents.The intra-and inter-provenance variations were calculated and compared.The comprehensive evaluation was conducted among all the provenances based on fuzzy subordinate function.The results showed that there were significant differences in the growth and photosynthetic traits among A.montana provenances,and inter-provenance variation surpassed intra-provenance difference.The height,diameter,biomass and seedling performance index of Xinluo district of Longyan,Shanghang and Changting provenances were better than those of others.Shanghang provenance was outstanding in net photosynthetic rate,while the provenance from Jiaocheng district of Ningde was remarkable in water utilization rate.The provenance from Xinluo district of Longyan had high rates of both photosynthetic capacity and water utility.The F_v/F_m,F_m and total chlorophyll contents were preferable in Changting and Youxi provenances.The provenance comprehensive evaluation revealed that Xinluo district of Longyan,Minhou,Shanghang,Changting,Jianyang district of Nanping and Youxi provenances ranked high based on fuzzy subordinate function and could be recommended for planting in northern Fujian Province.The research results can provide references for early evaluation,selection and promotion of superior provenances of A.montana,and provide important basis for further improving the breeding and scientific cultivation of the species.
