| 摘 要： | 将油松球果按大、中、小分为三个等次，对太岳林区六个林场18个球果样本出种情况及种子品质进行了研究。结果认为：本区油松球果平均单果出种量为1．44g，平均出种率为4．20％；种子平均千粒重为46．5g，平均发芽率为95．4％，平均发芽势为61．8％；球果单果出种量、种子千粒重、发芽势指标均与球果大小有关，随大、中、小规格依次降低；球果出种率、种子发芽率指标与球果大小无关，在大、中、小球果间无显著差异。

| Abstract: | The production and quality of eighteen Pinus tabulaeformis cone samples from six forest farms of Taiyue forest region were studied. The results showed, that seed production of single cone was 1.44g, the seed production rate 4.20%, the 1000-grain-weight 46.5g, the germinating rate of seed 95.4%, and seed germinating 61.8%. The seed production, 1000-grain-weight and the germinating rate of seed increased with increasing size of cone. |
