Modeling the longitudinal variation in wood specific gravity of planted loblolly pine (Pinus taeda) in the United States
Loblolly pine (Pinus taeda L.) is a major plantation species grown in the southern United States, producing wood having a multitude of uses including pulp and lumber production. Specific gravity (SG) is an important property used to measure the quality of wood produced, and it varies regionally and within the tree with height and radius. SG at different height levels was measured from 407 trees...
متن کاملRadial and longitudinal variation of Pinus taeda L. wood basic density in different ages
PALAVRAS-CHAVE Densidade Sentido medula-casca sentido base-topo ABSTRACT: The wood density is one of the parameters that most affect its properties, which makes it knowledge essential for any use indication. However, due to the high variability of this aspect within the tree, its determination shall consider a sampling throughout the stem. Thus, this study aimed to evaluate the longitudinal and...
متن کاملWater availability and genetic effects on wood properties of loblolly pine (Pinus taeda)
We studied the effect of water availability on basal area growth and wood properties of 11-year-old loblolly pine (Pinus taeda L.) trees from contrasting Florida (FL) (a mix of half-sib families) and South Carolina coastal plain (SC) (a single, half-sib family) genetic material. Increasing soil water availability via irrigation increased average wholecore specific gravity (SG) and latewood perc...
متن کاملStrength Properties of Juvenile and Mature Wood of Twelve Families of Loblolly Pine (Pinus Taeda L.)
The wood mechanical properties of progeny from twelve open-pollinated parent trees were examined. Six families were from parents which had high wood specific gravity and six were from parents which had low wood specific gravity. Thirty-two-year-old trees, that had been planted at Many, Louisiana, were sampled and juvenile and mature wood test specimens were prepared. Maximum crushing strength, ...
متن کاملLeaf Area Index (LAI) Change Detection Analysis on Loblolly Pine (Pinus taeda) Following Complete Understory Removal
The confounding effect of understory vegetation contributions to satellite-derived estimates of leaf area index (LAI) was investigated on two loblolly pine (Pinus taeda) forest stands located in Virginia and North Carolina. In order to separate NDVI contributions of the dominant-codominate crown class from that of the understory, two P. taeda 1 ha plots centered in planted stands of ages 19 and...
