Seed cone quality of Nigerian-grown Pinus caribaea var. hondurensis
Forest Ecology and Management, 1987Abstract The quality of mature seed cones of Pinus caribaea var. hondurensis Barr. and Golf, collected across the planting range (Latitude 4°54′N to 10°37′N) in Nigeria, was evaluated and related to the topoclimatological conditions of the sites of collection.

Bioenergy with wood residues from Pinus caribaea var. hondurensis
2019As espécies florestais do gênero Pinus são as mais utilizadas nas indústrias de processamento da madeira no Brasil, com a geração significativa de resíduos durante a conversão de toras em madeira serrada (desdobro). O trabalho teve como objetivo avaliar as características energéticas do resíduo do desdobro da madeira de Pinus caribaea var.

Journal of Plant Growth Regulation, 2018
Heterosis is the superiority of hybrids over their parental lines with regard to all kinds of agronomic traits and has been broadly investigated. However, the underlying genetic basis is so far obscure. To figure out the relationship between DNA methylation and heterosis in Pinus, we analyzed the cytosine methylation pattern in Pinus elliottii Englem. ×

Inter-provenance hybrids of Pinus caribaea var. hondurensis were progeny tested in Queensland, Australia in order to assess the feasibility of incorporating some desirable traits into the local breeding population, consisting largely of a single upland provenance Mountain Pine Ridge (MPR).

Growth and provenance variation ofPinus caribaeavar.hondurensisas an exotic species
The Southern African Forestry Journal, 2001CAMCORE has visited 33 populations of Pinus caribaea var. hondurensis in Belize, Guatemala, Honduras, El Salvador, Nicaragua, and Quintana Roo, Mexico. Seed collections have been made in 29 provenances from 1, 325 mother trees. A total of 21 provenances and sources of Pinus caribaea var.

Tolerance of Pinus caribaea var. hondurensis seedlings to five post-emergence herbicides
New Forests, 1990Five herbicides were evaluated for their potential to reduce reliance on directed white (mineral) spirits applications and hand weeding for grass control in P. caribaea var. hondurensis nurseries. Post-emergent applications of haloxyfop-methyl, fluazifop-P, fenoxaprop-ethyl and sethoxydim were identified as being selective to P.

Performance and genetics of provenance hybrids of Pinus caribaea var. hondurensis in Queensland
2001Two control-pollinated inter-provenance hybrids made between selected trees in the improved Mountain Pine Ridge (MPR) provenance, and selected trees in both Coastal and Guanaja Island provenances of Pinus caribaea var. hondurensis were evaluated along with a control (open-pollinated MPR provenance) at two Queensland sites (Tuan and Cardwell) to 6 - 7 ...

Thermally rectified wood acquires colors similar to those observed in tropical woods, improved resistance to fungi and weathering, higher dimensional stability and lower hygroscopicity. Little information is available on the effect of heat treatments on the machining properties of wood.

Abstract Frequency of foxtailing in five stands of Pinus caribaea aged between 3 and 9 years was found to vary between 7 and 20%. Heights of foxtails were greater than normals on average at all ages, whereas diameters were greater only at 3 and 5 years. Foxtail stems were more often straighter and had fewer malformations than normals.

Tarif de cubage Pinus caribaea var. hondurensis
1994Le but du présent travail était, initialement, la fourniture aux divers opérateurs forestiers intervenant dans les plantations de Pinus caribaea de la Chaîne Centrale (reboisements du Plateau de Tango, Col d'Amieu et Col des Roussettes) de nouveaux tarifs de cubage, adaptés aux caractéristiques dendrométriques des peuplements ...
