Green and Dry-Weight Equations for Above-ground Components of Planted Loblolly Pine Trees in the West Gulf Region
Prediction equations based on 130 sample trees from thinned and unthinned loblolly pine (Pinus taeda L.) plantations in central Louisiana re presented for the green and dry weights of aboveground tree components. Sample trees ranged from 2 to 21 in. dbh, 18 to 94 ft in height and from 9 to 55 yr in age. Significant differences in partial stem weight between trees from thinned and unthinned stan...
متن کاملEffect of Fertilization on Growth and Wood Properties of Thinned and Unthinned Midrotation Loblolly Pine (Pinus taeda L.) Stands
productivity; effects of different silvicultural treatments on the availability of limited resources; and the final consequence of resource availability on productivity and wood quality (Allen et al. 2005). An understanding of the effect of different management practices on productivity and quality of wood is of great importance both for wood growers and wood buyers. Therefore, our objectives w...
متن کاملHigh Tonnage Harvesting and Skidding for Loblolly Pine Energy Plantations
The southeastern United States has a promising source for renewable energy in the form of woody biomass. To meet the energy needs, energy plantations will likely be utilized. These plantations will contain a high density of small-stem pine trees. Since the stems are relatively small when compared with traditional product removal, the harvesting costs will increase. The purpose of this research ...
متن کاملCrown structure and leaf area index development in thinned and unthinned Eucalyptus nitens plantations.
The crown structure of Eucalyptus nitens (Deane & Maiden) Maiden 6 years after thinning, and the development of stand leaf area index both immediately and 6 years after thinning, were investigated. Thinning did not alter branch angle, branching density or the relationship between branch size and branch leaf area. However, larger branches were found in the lower crown of thinned trees and the in...
متن کاملA survival model for unthinned loblolly pine plantations that incorporates non-planted tree competition, site quality, and incidence of fusiform rust.
Future biomass yields are functionally related to the number of trees surviving at a given age. A stand level survival model was developed that incorporates competition of non-planted trees, site quality, and the incidence of fusiform rust (Cronartium quercuum [Berk.] Miyabe ex Shirai f. sp. fusiforme). The model consists of a system of two equations, one of which represents the number of survi...
