Morphological and chemical variations between juvenile wood, mature wood, and compression wood of loblolly pine (Pinus taeda L.)

Holzforschung, 2006
Abstract To better understand the within-tree variations between juvenile wood, mature wood, and compression wood, wood from a 35-year-old mature bent loblolly pine was separated into seven groups by different positions in the tree. Morphological and chemical structure analyses, including fiber quality, X-ray diffraction, sugar and lignin ...

Pyridine-catalyst acetylation of pine wood: influence of mature sapwood vs juvenile wood

European Journal of Wood and Wood Products, 2005
The aim of this study was to evaluate the effect that chemical modification by means of acetylation may have on juvenile vs mature pine sapwood. The results indicated that juvenile wood had clearly an adverse effect on acetylation; the magnitude of the reduction in WPG in juvenile wood was approximately 50% less than that of mature sapwood.

Wood maturation of distilled beverages

Trends in Food Science & Technology, 1998
A wide range of distilled beverages, including whisky and cognac, continue to be matured for many years in oak barrels. During maturation a range of physical and chemical interactions take place between the barrel, the surrounding atmosphere and the maturing spirit which transform both the flavour and composition of the drink.

Protoplasts in ‘Mature’ Wood Elements

Nature, 1955
IN a recent communication1, Mia reports the presence of nuclei and cytoplasm in mature vessel elements and fibre tracheids, and states that his findings are contrary to the observations of Esau and of Eames and MacDaniels in their text-books of plant anatomy. Mia's interpretations of the statements are very loose. He quotes Esau2: “in the mature state,

Wood Chemistry and the Maturation of Whisky

2020
Whilst the dominance of the wooden cask as a container for foods and liquids has diminished throughout the 20th century, to this day the global whisky industry is substantially reliant on the availability of oak casks. Originally, a convenient container for both wet and dry goods, including spirit, it became clear that the oak cask substantially ...
