| Abstract: | Seeds of Maackia amurensis collected from the State-owned Tree Farm of Palidianzi Town, Huanren County, were determined according to national standards. The results were 95.0% for seed purity, 86.3% for germination rate, 97% for seed superiority, 55.6 g for 1000-seed weight. Compared with the seeds collected froas Harbin city,secondary provenance which were similar to the germination rate, higher than 1000-seed weight and seed purity. |
