Physiology Research Made Forestation With Container-Grown Seedlings Successful

Effect of container type and seedling size on survival and early height growth of Pinus palustris seedlings in Alabama, U.S.A.

“…Points above the solid line are cases where the survival of container seedlings was greater than that for bare-root seedlings. Research on producing seedlings in tubes (cylindrical overlapping wrap of hard plastic) helped managers learn that the seedlings were too small and that ribs were needed to keep lateral roots from circling the pot and causing problems in subsequent development (Tinus and Owston, 1984). Although performance data exist for some older (no longer used) container types, published data on newer container types for longleaf pine are rare.…”

“…This provides a challenge to researchers since seedling quality research on one specific container type might not be applicable to others. What is needed is a way to measure the performance potential of a container seedling quickly and objectively, regardless of the brand of container (Tinus and Owston, 1984). Fig.…”

“…Some of the lateral roots enlarge and grow downward, developing into a multi-stemmed taproot system. Container-grown seedlings have a much greater planting window than bare-root in the East and Midwest, since their roots are continually growing which reduces or eliminates transplanting shock (Tinus and Owston, 1984 ). Bare-root seedlings can only be planted while dormant in the spring, allowing little time to establish an effective root system that can compete against annual weeds and survive during summer drought.…”
