Physical and mechanical properties of cross-laminated timber made from Pinus tecunumanii wood [PDF]

Revista Facultad Nacional de Agronomía Medellín
Timber from forest plantations is of great relevance to be used as a substitute for timber from natural forests; thus, reducing pressure on them and in such a way indiscriminate felling. Alternative building materials, like cross-laminated timber (CLT), are being sought in the world.

Lecanosticta acicola: A growing threat to expanding global pine forests and plantations. [PDF]

Mol Plant Pathol, 2019
Summary Lecanosticta acicola causes brown spot needle blight (BSNB) of Pinus species. The pathogen occurs mostly in the Northern Hemisphere but has also been reported in Central America and Colombia. BSNB can lead to stunted growth and tree mortality, and has resulted in severe damage to pine plantations in the past.

Balancing Breeding for Growth and Fecundity in Radiata Pine (Pinus radiata D. Don) Breeding Programme. [PDF]

Evol Appl, 2021
Abstract Tree breeding has focused on increasing stem volume growth with a cost to fecundity. However, fecundity is important in maintaining the fitness in natural stands and facilitating cross‐pollination to advance breeding populations. Understanding the inheritance of fecundity and the genetic relationship between fecundity and growth is essential ...

Identification of microsatellite loci in Pinus tecunumanii [PDF]

BMC Proceedings, 2011
Background Pinus tecunumanii has displayed good performance in tropical regions of Brazil and showed high potential for commercial exploitation. Embrapa Forestry and its partners own many of the species seed production areas. In spite of its importance, the majority of P. tecunumanii germplasm collections remain still genetically uncharacterized.

Seed-borne Fungi of Pinus tecunumanii Seeds in Tanzania

IOP Conference Series: Earth and Environmental Science, 2023
Abstract Seed health is an important attribute to be taken care of since it is from a healthy seed that a healthy plant is regenerated. Seed-borne fungi are among the severe pathogens causing significant losses in the quantity and quality of Pinus seeds. Fungi reduce seedling vigor and low seed germination to disease.

Multispecies comparison of host responses to Fusarium circinatum challenge in tropical pines show consistency in resistance mechanisms

Plant, Cell &Environment, Volume 46, Issue 5, Page 1705-1725, May 2023., 2023
Abstract Fusarium circinatum poses a threat to both commercial and natural pine forests. Large variation in host resistance exists between species, with many economically important species being susceptible. Development of resistant genotypes could be expedited and optimised by investigating the molecular mechanisms underlying host resistance and ...
