Pollination Bag Type Affects Ovule Development and Seed Yields in Pinus taeda L

Autor: Austin J Heine, Trevor D Walker, Jackson B Jett, Fikret Isik, Steven E McKeand

Publikováno v: Forest Science. 69:187-199

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

Hyperspectral Imaging Combined with Machine Learning for the Detection of Fusiform Rust Disease Incidence in Loblolly Pine Seedlings

Autor: Piyush Pandey, Kitt G. Payn, Yuzhen Lu, Austin J. Heine, Trevor D. Walker, Juan J. Acosta, Sierra Young

Publikováno v: Remote Sensing, Vol 13, Iss 18, p 3595 (2021)

Loblolly pine is an economically important timber species in the United States, with almost 1 billion seedlings produced annually. The most significant disease affecting this species is fusiform rust, caused by Cronartium quercuum f. sp. fusiforme. T

Performance Based on Measurements from Individual-Tree Progeny Tests Strongly Predicts Early Stand Yield in Loblolly Pine

Autor: Mohammad Nasir Shalizi, Trevor D Walker, Austin J Heine, Kitt G Payn, Fikret Isik, Bronson P Bullock, Steven E McKeand

Publikováno v: Forest Science.

To facilitate the utility of genetic improvement in loblolly pine, individual-tree volume (productivity) scores estimated from single-tree plot or row-plot progeny test designs were compared with stand-level volume per unit area from block plots. A l

Provenance and Family Variation in Biomass Potential of Loblolly Pine in the Piedmont of North Carolina

Autor: Jessica A Maynor, Steven E. McKeand, Ross W. Whetten, Fikret Isik, Kitt G. Payn, Trevor D. Walker, Austin J. Heine

Publikováno v: Forest Science. 67:312-320

Considerable genetic differences in loblolly pine (Pinus taeda L.) exist for growth, stem form, and wood quality traits that influence biomass/biofuel production. By planting genetically superior trees with desirable biomass/biofuel traits, it is pos

Modeling Self-Thinning Patterns in Loblolly Pine with Provenance and Family Effects

Autor: Benjamin C Smith, Bronson P. Bullock, Trevor D. Walker, Steven E. McKeand

Publikováno v: Forest Science. 66:712-725

Size-density trajectories and self-thinning boundary lines were modeled for two diverse provenances of Pinus taeda L. and five open-pollinated families within each provenance. The data used come from a single site with replicated 64-tree block plots

Pollination Bag Type Has a Significant Impact on Cone Survival in Mass Production of Controlled Pollinated Seeds in Loblolly Pine

Autor: Fikret Isik, Trevor D. Walker, Austin J. Heine, Steven E. McKeand, J. B. Jett

Publikováno v: Forest Science. 66:589-599

Since 2009, deployment of full-sib families of loblolly pine (Pinus taeda L.) has gained prominence in the southeastern United States. To produce full-sib seed, a pollination bag is used to isolate female strobili from outside pollen contamination, a

Autor: Steven E. McKeand, Trevor D. Walker, Fikret Isik

Publikováno v: Forest Science. 65:469-482

Acoustic time of flight and drill resistance (surrogates for wood stiffness and density, respectively) were measured on 11,097 standing trees from 269 pollen-mix families of loblolly pine (Pinus taeda L.) in 6- to 9-year-old progeny tests at eight si
