Bruce J. Zobel,Johannes P. van Buijtenenstem.Management types are remarkably easy to use thanks to a well-defined structure and a well-thought-out design. I’m sure that once you spend some time programming .NET management applications, you will quickly overcome any initial confusion and grow to appreciate the elegance and straightforwardness of the System.Management object model.

The Effect of Provenance Variation and Exotic Plantations on Wood Properties,mall limbs with relatively right-angled branches, making them better adapted to ice and snow. Geographic growth differences are sometimes genetically set; for example, when high-elevation trees are grown at lower elevations they often maintain their slow growth and good form (Langlet 1967).

Variation Within and Among Trees,ture of variable woods. Often the user of wood must “overbuild” in the sense that the construction must be designed for the weaker, not the stronger wood members, so that much potential strength is “wasted”.

1431-8563 ies, the causes of wood variation, and how best to develop wood for desired products. There is voluminous literature related to these subjects, but it is neither well known nor appreciated by foresters because the publications are often not available or are not well understood by the forester or by

Wood Variation and Wood Properties,ology of loblolly pine (.) tracheids and the paper made from them, as discussed by Barefoot et al. (1970). The subject of cell morphology and usefulness for the final product was covered in a general way by Keating (1983). Before the causes and control of wood variation are discussed, it is necessary to know just what wood is.

Wood Properties Affected by Environmental, Biological, and Other External Agencies,. In 1962 (Anon 1962) TAPPI published Monograph No. 24 with 883 references, related to the effect of environmental and genetic factors that would affect pulpwood quality. Only a few of these references are repeated in this chapter.

Control of Wood Properties by Breeding, the large natural variability in wood properties. The opportunities for genetic control of wood are particularly attractive, since wood properties are generally strongly inherited. Many of the aspects of the genetics of wood are covered in Chapter 11 of Zobel and Talbert (1984) entitled “Wood and Tree Improvement.”
