Nucleotide diversity in eight genes related to wood formation was investigated in two pine species, Pinus pinaster and P. radiata. The nucleotide diversity patterns observed and their properties were compared between the two species according to the specific characteristics of the samples analysed. A lower diversity was observed in P. radiata compared with P. pinaster. In particular, for two ge...
In this study some of the important properties of experimentally manufactured wood– plastic composites (WPC) were determined. Specimen having 60% and 80% particle and fibre of radiata pine (Pinus radiata ) were mixed with polypropylene (plastic) and four different additives, namely Struktol TR 016 which is coupling agent, CIBA antimicrobial agent (IRGAGUARD F3510) as fungicide, CIBA UV filter c...
Pitch canker, caused by Gibberella circinata, was discovered in California in 1986. Although initially quite damaging to Monterey pines (Pinus radiata), the severity of pitch canker has moderated in areas where the disease was first observed and some trees appear to have recovered completely. The absence of symptoms on trees that were once severely affected implies they have become more resista...
The information about the impacts of thinning on availability micro-nutrients, as well macro-nutrients other than N, P and K, is still scarce. We assessed changes in concentrations 12 elements (Al, B, Ca, Cu, Fe, Mg, Mn, Na, Zn) with needle age (current year or 1-year-old) three early treatments two most widely distributed pines SW Europe: P. pinaster radiata. Four were setup triplicate: contro...
