Book Description
Excerpt from Genetics of Virginia Pine Pinus virginiana (mill), variously known as Virginia, Jersey, possum, spruce, short straw, scrub, poverty, and old field pine, is a species of contrasts. It is despised by the logger but liked by the forester and the pulp mill manager in most areas of its range. The logger's negative reaction to Virginia pine results from the tree's small size and to its persistent branching habit, factors which adversely affect harvesting production. Dominant and codominant trees average only 23 to 25 meters tall and 28 to 30 centi meters at 50 years.2 Older trees may attain heights to 35 meters and diameters to 90 centimeters (harlow and Harrar but even they often retain branches and branch stubs the length of the bole below the live crown. Despite these deterrents, the species has gained the respect of foresters because of good volume and dry-weight yields at rota tion ages of 25 to 30 years (newland 1968, nc. State Univ. And of pulp mill managers because of suitability of the fiber for fine paper and groundwood products. These attributes are responsible for a recent planting program of several thousand acres annually. Secondary uses of Virginia pine include lumber and structural timber from sawlog-sized trees, and Christmas trees which are harvested at rotation ages of 6 to 10 years. This paper reviews the current status of research on the genetics of, Virginia pine. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
