| 摘 要： | 通过对长白落叶松种子园各无性系结实量、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。

| Abstract: | 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. |
