Abstract: Seed physical properties，seed germination rate，sprouting vegetable yield，and sprout nutritional components of eight provenances of Toona sinensis seeds were tested using indoor experiment. Results showed:（1） significant differences among provenances for seed length （P = 0.036 8），seed width （P = 0.025 8），seed water content （P = 0.002 9），thousand kernel weight （P = 0.020 0），and seed germination rate （P ＜ 0.000 1）. Significant differences were also found for sprout yield （P ＜ 0.000 1），soluble protein content of sprouts （P = 0.002 6），amino acid content of sprouts （P = 0.003 7），and Vitamin C content of sprouts （P = 0.034 0）. （2） Seed germination rate have significant positive correlation with sprout yield （r = 0.692 8，P ＜0.000 1） and Vitamin C content of sprouts （r = 0.480 9，P = 0.000 6）；thousand kernel weight had a significant positive correlation with amino acid content of sprouts （r = 0.434 8，P = 0.002 3），sprout length （r = 0.531 3，P = 0.000 1），and weight per sprout （r =0.473 5，P = 0.000 8）；and content of soluble protein of sprout had a significant negative correlation with content of amino acid of sprout （r = －0.705 6，P＜0.000 1）. （3）For high sprout yield，the best provenance was Xunyang with an average of 1 g of seed producing 9.23 g of sprouts. The best provenances were Chengdu for high soluble protein content，Shijiazhuang for amino acid content，and Sui-ning for sprout vitamin C content.［Ch，1 fig. 3 tab. 9 ref.］
