35个沿海道格拉斯冷杉树的胚胎遗传负荷进行了评估，从比较健全的种子集自花授粉和异花授粉，也就是说，从相对自育性的测定。估计35棵树的范围从约3至约27个致死当量每个受精卵活跃在胚胎阶段，与中位数树进行约10个致死当量每个受精卵。道格拉斯冷杉的相对自育性与其他针叶树种的报道进行了比较，并与果蝇，赤拟谷盗和人的遗传负荷进行了比较。
Thirty-five coastal Douglas-fir trees were evaluated for embryonic genetic load from comparisons of sound seed set following self- and cross-pollinations, that is, from determinations of relative self-fertility. Estimates for the 35 trees ranged from about 3 to about 27 lethal equivalents per zygote active in the embryo stage, with the median tree carrying about 10 lethal equivalents per zygote. Relative self-fertility of Douglas-fir was compared with that reported for other coniferous species, and genetic load was compared with that reported for Drosophila, Tribolium, and man.
