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


We investigated several possible causes of 1-0 stunt inDouglas-fir [Pseudotsuga menziesii (Mirb.) Franco] intwo fumigated bareroot nurseries. The results suggest that(1) delayed development of a root system contributes toseedling nutrient stress; (2) lack of ectomycorrhizae didnot cause stunt; (3) root diseases were not involved; and(4) some soil microorganisms on root surfaces may haveproduced toxins that prevented nutrient-absorbing hairroot development. We conclude that some combination offactors limits root system development, leading to nutrientdeficiency, bud set, and stunting.
