对从美国３个州（宾夕法尼亚、纽约和田纳西州）引进的栎属３个树种北方红栎、柳叶栎和红栎的２１个种源进行了两次播种和容器育苗试验。初步掌握了栎属种子砂床播种、芽苗移栽、容器育苗的关键技术。对栎属种子的发芽、芽苗和苗木的生长过程等有了一定的了解。发现栎属不同树种间和种内种源、家系间在种子体积、千粒重、发芽率、３０ｄ萌叶率和苗高生长等性状均存在极显著变异，试验数据表明种子体积北方红栎为大（其中宾夕法尼亚州家系１７２最大），其次是红栎和柳叶栎。千粒重以北方红栎为重（其中宾夕法尼亚州家系１７２最重），其次是红栎和柳叶栎。发芽率为北方红栎最高（其中宾夕法尼亚州家系１９１为１００％），其次是红栎和柳叶栎。３０ｄ萌叶率和苗高生长以柳叶栎为高（田纳西州种源９７０１ＴＮ最高），其次是红栎和北方红栎。在种间和种内不同种源、家系间种子千粒重与年终苗高生长相关不显著。
Twelve sowing and container seedling experiments were conducted on 21 provenances of Quercus mongolica, Quercus acutissima and Quercus acutissima, introduced from three American states (Pennsylvania, New York and Tennessee). Preliminary grasp of the Quercus seed sand bed sowing, seedling transplanting, container seedling key technologies. Have a certain understanding of the germination of Quercus seed, bud and seedling growth process. The results showed that there were extremely significant variations in the seed volume, 1000-grain weight, germination rate, leaf germination rate at 30 days, seedling height growth and other traits among different species and species of Quercus species. Among them, Pennsylvania was the largest with 17-2), followed by red oak and willow oak. One thousand kernel weight is dominated by red oaks of the North (Pennsylvania Family 17-2 heaviest), followed by red oak and willow oak. The germination rate was the highest in northern red oak (Pennsylvania 19-1 family of 100%), followed by red oak and willow oak. The leaf rate and seedling height of 30 days were higher than that of Quercus glauca (Tennessee provenance was highest at 9701TN), followed by red oak and northern red oak. In the interspecific and intraspecific germplasm, the 1000-grain weight of the pedigree was not significantly correlated with the year-end seedling height growth.
