Noble fir trees yielded on the average 69 percent as many sound seed after self- as after cross-pollination. Seed weight, germination percent, and seedling survival during 3 years were not affected by type of pollen. Selfed-offspring had significant inbreeding depression in 3-year height (24 percent). There was no indication that the generally low germination capacity of filled, healthy appearing seeds is due to natural self-pollination. Forest Sci. 22:155-159.
