Investigations of the Cause of First-Year Stunting of Douglas-fir Seedlings in Bareroot Conifer Nurseries

Linderman, R. G., Russell, K. W., and Tanaka, Y. Tree Planters' Notes 52(1):19-25. 2007. conference, p. 437-440 USDA Forest Service, Southern Research Station, General Technical Report SRS-71. Kristina F. Connor, ed. 2004.

We investigated several possible causes of 1-0 stunt in Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] in two fumigated bareroot nurseries. The results suggest that (1) delayed development of a root system contributes to seedling nutrient stress; (2) lack of ectomycorrhizae did not cause stunt; (3) root diseases were not involved; and (4) some soil microorganisms on root surfaces may have produced toxins that prevented nutrient-absorbing hair root development. We conclude that some combination of factors limits root system development, leading to nutrient deficiency, bud set, and stunting.
