2008 interim guidelines for growing longleaf pine seedlings in container nurseriesThis article is part of a larger document. View the larger document here.
Production of container longleaf pine (Pinus palustris) seedlings for reforestation and restoration plantings exceeds that of bareroot production, but information on container production techniques has been slow to develop. Because success of those outplantings requires quality seedlings, interim guidelines were proposed in 2002 to assist nursery managers and tree planters in developing and using the best stock possible. The guidelines were intended to be updated as new information was generated. During the past 6 years, additional studies have confirmed most provisions of the interim guidelines, except that presence of buds (number and color) as originally described in the guidelines does not appear to be a useful metric. In addition, some new parameters have been added. This report synthesizes that new information and revised guidelines are presented.
