为了评价种子园花粉对周围背景源污染的潜在影响，我们用园外花粉和园内花粉对花旗松(Posus Tsuga menziesii(MIRB.)佛朗哥)沿海内陆过渡带种子园。由此产生的后代在一个过渡区和一个沿海地点进行了测试。经过9个生长季节后，两种花粉源在两个地点的存活率都在90%以上，不同花粉源引起的树高差异在统计学上没有显著差异。作为对照的野生林分作业苗木比“受污染”的苗木短17%。讨论了这些结果对果园管理的影响。
To evaluate the potential effects of seed orchard pollen contamination from surrounding background sources, we made control pollinations with outside orchard pollen and inside orchard pollen on trees of a Douglas-fir (Pseudo tsuga menziesii (Mirb.) Franco) coastalinterior transition zone seed orchard. The resulting progeny were tested on a transition zone and a coastal site. After nine growing seasons, survival was above 90% on both sites for both pollen sources, and the trees height differences due to pollen source were statistically nonsignificant. Wildstand operational seedlots, used as controls, were 17% shorter than the "contaminated" seedlings. Orchard management implications of these results are discussed.
