Loblolly pine (Pinus taeda L.) is the most widely planted forest tree species in the United States. Most of the seedlings used to establish these plantations come from seed collected in open-pollinated seed orchards, but an increasing number are comi

Over the past years, a great deal has been learned about variation in wood prop erties. Genetic control is a major source of variation in most wood properties. Wood is controlled genetically both directly in the developmental or internal pro cess

For many years most tree improvement programs included growth, form, adaptability, and pest resistance in their assessments but did not include wood properties as such. It was recognized that tree form, growth rate, and pest tolerance could all affec

As will be evident in the following sections, the inheritance of wood density is uniformly strong. Most of the genetic variability is of the additive type, enabling good gains from a selection and breeding program as well as from a vegetative propaga

An explanation has already been given in Chapter 1 about how external factors (environmental), combined with internal factors, control the formation and qualities of wood. Both external and internal factors influence the physiology of the tree which,

Initially, only a few tree improvement programs included wood as a characteristic to be genetically manipulated. Emphases in the early programs were on adaptability, pest tolerance, growth rate, and tree form. Certainly those characteristics are of i

Discussions as to which wood properties should be included in a breeding program occur in a number of places in this book. Some are repeated and summarized in this chapter; this is especially true of Chapter 13 (for example see Chap. 13.2.1). The sum

A general definition of specific gravity and wood density was given in Chapter 1, but it will be of value to repeat a summary of it here. The two terms will be used interchangeably, since they measure the same thing although results are expressed usi

The wood produced by trees grown from different seed sources or provenances can differ significantly. If the effects of provenance or seed source on wood are to be understood, the terms need to be briefly defined. The definitions by Zobel et al. (198
