An Annual Tree Survival and Diameter Growth Model for Loblolly and Slash Pine Plantations in East Texas
An annual growth model that predicts individual tree survival and diameter growth was developed for loblolly pine (Pinus taeda) and slash pine (Pinus elliottii) trees in East Texas as a function of individual-tree diameter, plantation age, basal area per acre, dominant height, quadratic mean diameter, and presence of fusiform rust (Cronartium quercuum [Berk.] Miyabe ex Shirai f. sp. fusiforme)....
متن کاملEvaluation of Resistance to Fusiform Rust in Loblolly Pine from East Texas
A set of 21 loblolly pine families produced by crossing trees from east Texas were tested for resistance to fusiform rust disease. The parents of these families were surviving trees in stands that experienced extensive mortality in the 1960s due to southern pine beetle infestation. Seedlings were grown in tubes in a greenhouse and artificially inoculated with C. quercuum from five different sou...
متن کاملA Modified Stand Table Projection Growth Model for Unmanaged Loblolly and Slash Pine Plantations in East Texas
Four methodologies to project future trees per acre by diameter class were compared to develop a new modified stand table projection growth model for unmanaged loblolly pine (Pinus taeda L.) and slash pine (Pinus elliottii Engelm.) plantations in East Texas. The new models were fit to 92,882 observations from 153 permanent plots located in loblolly pine plantations and 33,792 observations from ...
متن کاملDecline in Values of Slash Pine Stands Infected with Fusiform Rust
Losses in product values due tofusi form rust , caused by Cronart ium quercuum (Berk.) Miyabe ex Shiraifi sp. fusiforme, were estimatedfrom four, 2.5-yr-old slash pine, Pinus elliotii Engelm., plantations planted in southern Mississippi over a range of sites with different growth potential and expected rust infection levels. The percentage infected stems rangedfrom 2.5% to 62% at age 2.5. The c...
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...
