Root Egress in Lodgepole Pine Seedlings Grown in Peat and Planted in Soil

Seedlings of lodgepole pine (Pinus contorta Dougl. var. Zatifolia Engelm.) were grown in 49 cm3 containers filled with peat or soil and subsequently transplanted into 18cm diameter pots filled with soils ranging in texture from sandy loam to clay loam. Watering intensity did not significantly influence the growth of transplanted seedlings. Seedlings reared in peat, and held for planting past their optimum size relative to container size, became progressively less able to adapt to soils with increasing clay content the longer they were held. When seedlings were reared in the same soil into which they were to be transplanted, clay content in the soil did not influence root egress at all.
