摘　　要：于2000年和2001年从北美引进南方红栎、北方大果栎、水栎、柱栎、黑栎、北美白栎和英国栎等7个树种,15个种源在江苏进行育苗试验结果表明,不同树种、种源间发芽时间、场圃发芽率、苗高、地径生长性状有明显变异。种子发芽时间柱栎、黑栎依阿华和密苏里种源最早;其次为北方大果栎伊利诺斯种源、南方红栎阿肯色种源、黑栎安大略种源,水栎各种源发芽均迟。总出苗率以黑栎密苏里种源最高(达83 3%),水栎得克萨斯种源和北方栎蒙大纳种源较低(仅为15 7%和20 0%)。1年生苗高生长量以英国栎最大,其次是南方红栎、北方大果栎和水栎,黑栎和北美白栎生长量最小。同时,还研究分析比较了不同树种苗高季节生长节律。The performances in Jiangsu of seven introduced Quercus species(including fifteen provenances) from North America have been investigated.Results indicated that there were significant differences among germination time,germination percentage and seedling growth(height and diameter)in various species and provenances.The seeds of Quercus stellata,provenances of Q.velutna from Iowa and Missouri germinated earliest.And the seed of provenances of Q.macrocarpus from Illinois,of Q.rubra from Arkansas and of Q.velutna from Ontario did next while all provenances of Q.nigra did latest.As for germination percentage,provenance of Q.velutna from Missouri(up to 83 3%) excelled that of Q.nigra from Texas(15 7%) and of Q.macrocarpus from Montana (20 0%).In yearling high growth,Q.robur showed best performance,and Q.rubra did next whereas Q.macrocarpus,Q.nigra,Q.vecutna and Q.alba did worst.An analysis was also made of the seasonal high growth rhythm of various species.
