摘　　要：1年生苗期数据表明,小兴安岭南部地区可以引种杂种落叶松。日本落叶松×兴安落叶松高生长表现突出,其次是兴安落叶松×日本落叶松,日本落叶松×长白落叶松高生长较差,长白落叶松家系、优良种源生长都差,兴安落叶松优良种源长势最弱。生长较快的5个家系同当地生产对照相比快25.1%,与兴安落叶松优良种源比快52.9%,所有的杂种落叶松家系高生长都大于对照和兴安落叶松优良种源,杂种落叶松适应性较好,播种当年未发现有冻害现象。The data of 1 year old seedling period south of Xiaoxing＇ anling. Larix kaempferi × L. gmelinii × L. kaempferi is in the next place. L. indicates that hybrid larch can be introduced in the gmelinii displays high growth most prominently. L. kaempferi × L. olgensis is relatively poor in high growth. L. olgensis family and superior provenance both grow poorly; the superior provenance of L. gmelinii grows worst. Five families with quick growth are quicker than the check of local by 25.1% , and the superior provenance of L. gmelinii by 52.9% respectively. All hybrid larch families are better than the check and the superior provenance of L. gmelinii in high growth. The adaptability of hybrid larch is fairly good, and there is no freezing injury phenomenon within the seeding year.
