Effects Of Container Density On Growth And Cold Hardiness Of Douglas-Fir Seedlings

Douglas-fir [Pseudotsuga menziesii (Mirb) Franco] seedlings were grown in 2.7 cubic inch plastic containers for five months at densities of 25, 50, 75 and 100 ft-2 in a greenhouse. Low densities produced shorter, thicker-stemmed plants with greater shoot and root dry weights, lower shoot-root ratios, and a greater degree of cold hardiness.
