摘要
通过对长白落叶松种子因各无性系结实量、种子产量及播种品质等因子的定点研究，基本上掌握了长白落叶松种子园各无性系结实量及播种品质差异，选择出17个优质高产无性系，用选出的优质高产无性系构成新的生产群体，种子产量提高1．3～1．6倍，种子发芽率达到60％（国家Ⅰ级种子标准）；各无性系间种子产量、播种品质等因子差异极大。
Factors （fruit bearing amount, seed yield, sowing quality） of clones of Larix olgensis seed orchard were studied. Fruit bearing amount, differences of sowing quality of Larix olgensis seed orchard were mastered basically. Seventeen superior high-yielding clones were selected to form new population of seed production; seed yield would increase by 1.3-1.6 times, seed germination reaches 60% （first-grade state seed standard） ;there are significant differences among fruit bearing amount ＆ sowing quality of clones.
