Artificially increasing pollen supply (supplemental mass pollination (SMP)) to conifer seed orchards has the potential to increase seed yields and improve the genetic worth of seed crops that would otherwise suffer from the detrimental effects of pollen contamination and unbalanced paternal contribution. However, success rates, measured as the proportion of seed fertilized by SMP, have been low. This review examines the concepts underlying SMP and presents data for two SMP field trials with Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) and white/Engelmann spruce (Picea glauca (Moench) Voss, Picea engelmannii Parry ex Engelm.). The trial results are discussed with respect to pollen fertility, pollination technique, and competing pollen cloud density. I also summarize methods for ensuring the successful handling of pollen ex situ.
人为增加针叶树种子园的花粉供应（补充群体授粉，SMP）有可能提高种子产量，并改善种子作物的遗传价值，否则这些种子作物会受到花粉污染和父本贡献不均衡的不利影响。然而，以SMP受精种子的比例衡量的成功率一直很低。本综述探讨了SMP背后的概念，并展示了两项针对花旗松（Pseudotsuga menziesii (Mirb.) Franco）和白云杉/恩氏云杉（Picea glauca (Moench) Voss, Picea engelmannii Parry ex Engelm.）的SMP田间试验数据。针对花粉育性、授粉技术和竞争花粉云密度对试验结果进行了讨论。我还总结了确保在异地成功处理花粉的方法。
