Available in PDF, EPUB and Kindle. Book excerpt: Longleaf pine (Pinus palustris Mill.) seeds are sensitive to damage during collection, processing, treatment, and storage. High-quality seeds are essential for successfully producing nursery crops that meet management goals and perform well in the field. Uniformity in the production of pine seedlings primarily depends on prompt and uniform seed germination, early seedling establishment, and a variety of cultural practices that are applied as the seedlings develop. The best collecting, handling, and processing methods maximize performance attributes and reduce the need for extensive nursery cultural practices to compensate for poor seed quality. Guidelines are presented that will help seed dealers, orchard managers, and nursery personnel produce high-quality longleaf pine seeds and improve the efficiency of nursery production.

Book excerpt: Describes a prototype whitebark pine seed scarifier developed by the Missoula Technology and Development Center that allows workers to nick (scarify) seeds three times as fast as if they were doing so by hand, with reduced risk of injury. Populations of whitebark pine have declined over the past century because of white pine blister rust, insect infestations, and fire suppression. Whitebark pine seeds are a favored food of the grizzly bear, a threatened species protected by the Endangered Species Act in the 48 contiguous States. Whitebark pine trees, which may be the only trees growing in some sub-alpine and alpine areas of the northern Rocky Mountains, also catch snow during the winter. The drifts melt more slowly than thinner snowpack in bare areas, extending runoff. The scarifier should help reduce the costs of growing whitebark pine seedlings, possibly allowing more whitebark pines to be planted. Seeds collected from white-bark pine trees resistant to blister rust are germinated in nurseries. The germination rate increases from about 5 percent to 60 percent or more if each seed has a 1-mm-deep nick. Workers can nick about 400 seeds an hour by hand, compared to 1,500 seeds an hour when using the prototype scarifier. The scarifier costs about $1,000 to fabricate. Fabrication drawings will be available from the Missoula Technology and Development Center.
