Over Winter Cold Storage of Red and White Pine Transplants Successful in Northern Indiana
Overwinter cold storage at the Jasper-Pulaski Nursery in northern Indiana kept red and white pine (Pinus resinosa Alt, and P. strobus L.) transplants in good condition for spring planting. However, survival of 2-0 red and white pine seedlings stored in the same manner was poor. Overwinter storage of such seedlings seems inadvisable. Cold storage was tried at the northern Indiana nursery because the only other conifer-producing State nursery in southern Indiana) was closed, and because soil in the northern nursery commonly is still frozen when seedlings are needed for early spring planting in the south. Deffenbacher and Wright (1) have reported getting excellent first-year survival of four western conifers that were kept 8 months in cold storage. So in Indiana, where the storage period will seldom exceed 4 months, survival of stored trees should be satisfactory once adequate lifting schedules and storage techniques are developed.
