A Comparison of Three Packaging Methods for Slash Pine Seedlings

Forest tree nurseries in North Carolina have dipped seedling roots in a clay slurry to prevent root drying since 1963 (Bland 1964, Davey 1964). This method has replaced the conventional practice of packaging the seedlings in wet sphagnum moss. Notable seedling success has also been obtained in Mississippi by placing barerooted seedlings in Kraftpolyethylene bags (Ursic 1964). Seedlings packed in this manner have been stored up to 8 weeks in a warehouse with no resultant reduction in survival (Williston 1965). A study was conducted during the 1965-66 planting season to determine the relative effectiveness of clay dip packaging in relation to the conventional method of packaging with sphagnum moss. smaller scale, the packaging of barerooted slings in sealed K-P bags was evaluated. Specifically, answers were sought for these questions: (1) How does packaging technique affect the initial survival of slash pine seedlings following outplanting; and (2) How does the length of storage after packaging affect survival?
