Longleaf pine is a highly desirable species, resisting fire, insects and pathogens, and produces quality solid-wood products, but regeneration of the species has been difficult. Natural regeneration is feasible only on a small portion of the area considered to be longleaf pine type. Therefore, artificial regeneration must become a reliable means of regenerating the species if restoration of the...
The performance of container and bareroot loblolly pine (Pinus taeda L. ) seedlings from the same improved seedlot was compared on highly productive bottomland sites in South Carolina. At the time of planting, size and quality of the open-grown container stock were equal to or better than bareroot material. When outplanting conditions were ideal, field plantings in March, April, and May of 2 su...
Eastern black walnut (Juglans nigra L.) has potential for agroforestry practices in the eastern United States because of its value for nuts and timber; however, practices for optimum nut production are poorly defined. Studies were conducted to determine the type of planting material that can assure successful establishment of black walnut for nut production. The first study compared the surviva...
Regenerating longleaf pine by artificial means is an essential component of restoring the ecosystem across most of its range because there are limited acres of longleaf stands remaining. Establishing longleaf pine is an early step in the ecosystem restoration process. An overview discussion of artificial regeneration techniques and related issues are presented this paper. Other papers follow in...
--The possibility of growing sizeable shade trees (1%" and over in caliper) in containers is exciting to both arborists and nurserymen. Advantages include reduction in transplant shock, ease of retail storage, extension of the planting and shipping seasons, and less need for nursery space. However, problems include difficulty in overwintering in northern climates, root girdling, potbound trees,...
A previous study revealed low survival rates for Japanese larch (Larix kaempferi) summer-planted seedlings grown in Hiko-V-120 containers. This examines nursery practices that could potentially prevent deterioration of the seedling water balance after planting to improve rate this species, which has a drought tolerance. During summer planting, we tested (1) hardening or high-potassium fertiliza...
