Lifting Dates, Chilling Hours, and Storage Duration on Slash Pine Seedling Root Growth Potential, Growth, and Survival

Annually, the Southern United States produces over 1 billion forest tree seedlings, the majority of which are conifers (pine) produced as bareroot seedlings. Typically grown for less than a year, seedlings are then lifted from the soil, packed in boxes, bags or bundles, and placed in cold storage before being transported to sites for reforestation. Lifting operations typically occur from late November to early March each year. On occasion, however, circumstances require seedlings to be lifted later or stored longer than recommended. Over three lifting seasons, we investigated pine seedling storability based on a series of delayed lift dates (January through March) and varying storage durations (0 to 14 weeks). Data patterns varied among the three seasons. In general, later lift dates and longer storage durations resulted in reduced seedling growth and survival. This paper was presented at the 2019 Joint Annual Meeting of the Northeast and Southern Forest Conservation Nursery Associations (Atlantic City, NJ, July 23–25, 2019).
