Beschreibung:
Seedlings of white spruce (Piceaglauca (Moench) Voss var. albertiana (S. Brown) Sarg.), lodgepole pine (Pinuscontorta Dougl. var. latifolia Engelm.), and Douglas fir (Pseudotsugamenziesii (Mirb.) Franco) were grown in closely packed, extruded peat cylinders (sausages) of different lengths, diameters, and densities within a range practical for operational use. The highest density (0.23 g/cm3) was limiting to all growth parameters for all species in all rooting volumes – espacements. In lower densities, all growth parameters were linearly correlated to rooting volume. In the smaller rooting volumes – seedling espacements, growth restrictions were partially relieved by compression of the peat up to density 0.20 g/cm3.
