Book Description
S2The study was designed to compare direct seeding with several planting procedures in terms of tree performance through the period of a stand rotation. As part of the study, sample seedlings were excavated in 1962 to determine the early effects of the treatments on root systems. This paper describes and pictures the root systems, and the differences among them that related to the method of seedling establishment.S3.

Book Description
ing damage ranged from odor. to general visual appearance. Attributes of seedling quality are categorized as either to cutting buds. to scraping bark to detect dead cambium. performance attributes (RGP. frost hardiness. stress resistance) One nursery reported using frost hardiness as an indicator of or material attributes (bud dormancy. water relations. nutrition. when to begin fall lifting. but none reported using it as an morphology). Performance attributes are assessed by placing indicator of seedling quality before shipping stock to customers. samples of seedlings into specified controlled environments and evaluating their responses. Although some effective short 23.4.3 Stress resistance cut procedures are being developed. performance tests tend Only three nurseries measure stress resistance. They use to be time consuming; however, they produce results on whole the services of Oregon State University and the test methods plant responses which are often closely correlated with field described in 23.2.3. One nursery reported that results of stress performance. Material attributes. on the other hand. reflect tests did not agree well with results of RGP tests and that RGP only individual aspects of seedling makeup and are often correlated better with seedling survival in the field. Most stress poorly correlated with performance. tests are conducted for reforestation personnel rather than for Bud dormancy status seems to be correlated. at least nurseries.

S2This list of publications was compiled as reference material for the forester, forestry researcher, and forestry student. It contains references to 1,436 publications by staff members of the Northeastern Forest Experiment Station and their cooperators during the period 1950-65. It does not include publications of Central States projects that were incorporated into the Northeastern Station research program in the reorganization of March 1966.S3.

Book Description
Because of the growing need for wood fiber in the pulp and paper industry there is an opportunity for sawmill operators to increase their income by converting hardwwood sawmill residues (slabs, edgings, and trim) to pulp chips. By selling wood chips and reducing residue-disposal costs, sawmills could improve their utilization of sawlogs. But to justify the installation of debarking and chipping machines, and to know what such machines could contribute to his business, the sawmill owner must have a thorough understanding of the costs involved in chip production. To help him in this we have made case studies of seven sawmills in southeastern Ohio, eastern Kentucky, and Tennessee, and have analyzed all the factos of cost involved in chip production.
