Sesquiterpene biosynthesis in maritime pine needles

Phytochemistry, 1984
Abstract The biosynthesis of sesquiterpene hydrocarbons was studied in maritime pine ( Pinus pinaster ) needles by incorporation of 14 CO 2 , [1- 14 C] acetate and [2- 14 C] mevalonate. It was shown that the mechanisms of sesquiterpene biosynthesis are different according to the applied tracer.

Grading of Portuguese Maritime Pine Small-Diameter Roundwood

Journal of Materials in Civil Engineering, 2017
AbstractThis paper presents work carried out with the aim of characterizing the mechanical behavior and developing visual and machine-strength grading systems for Portuguese maritime pine roundwood for structural applications. Two samples of forty maritime pine logs each were collected, one in a northern region of Portugal and another in an interior ...

Micronutrient distribution in 16-year-old maritime pine

Tree Physiology, 1992
Concentrations and contents of the micronutrients Fe, Mn, Zn, Cu, and B were measured in various tree compartments of a 16-year-old stand of maritime pine (Pinus pinaster Soland in Ait.). The micronutrients were actively redistributed within the tree. The longer-lived aerial tissues, trunks and branches, constituted the major micronutrient reservoirs ...

Transpiration of a 64-year-old maritime pine stand in Portugal

Oecologia, 1996
The transpiration, sap flow, stomatal conductance and water relations ofPinus pinaster were determined during spring and summer in a 64-year-old stand in Ribatejo (Portugal). The transpiration of the pine canopy was determined from sap flow or eddy covariance techniques.

Maritime Pine (Pinus pinaster Sol.)

1991
The genus Pinus is the most important among the Conifers, with about 80 species, one of which is the maritime pine, Pinus pinaster Sol. (2n = 24). It is a resinous tree with persistent and very long needles two or three of which are grouped into fascicles with a basal sheath.

Maritime Pine Pinus Pinaster Aiton

2018
Maritime pine (Pinus pinaster Aiton) is the most abundant conifer in the Mediterranean basin. Currently, maritime pine is considered to be a model conifer species for study of the adaption responses to drought stress from a genomics approach. In this context, the availability of protocols that allow not only mass vegetative propagation of selected ...

Transverse shrinkage in maritime pine juvenile wood

Wood Science and Technology, 1997
This paper reports experimental results concerning the transverse shrinkage variability within and between trees of two samples composed of 17 eleven-year-old and 20 twenty-year-old maritime pine trees harvested in two stands at the Forest Research Centre of INRA Pierroton in Aquitaine.

A maritime pine antimicrobial peptide involved in ammonium nutrition

Plant, Cell & Environment, 2011
ABSTRACTA large family of small cysteine‐rich antimicrobial peptides (AMPs) is involved in the innate defence of plants against pathogens. Recently, it has been shown that AMPs may also play important roles in plant growth and development. In previous work, we have identified a gene of the AMP β‐barrelin family that was differentially regulated in the ...

Somatic Embryogenesis in Maritime Pine (Pinus Pinaster)

1995
Maritime pine (Pinus pinaster) has originated from the central and western coasts of the Mediterranean. It is well adapted to sandy soil in temperate climates. Small natural forests of maritime pine can still be found in many African and European countries.
