Extracellular lipase production by a sapwood-staining fungus, Ophiostoma piceae
World Journal of Microbiology & Biotechnology, 1995The extracellular lipase production of a sapwood-staining fungus, Ophiostoma piceae, grown in liquid media, was optimally active at pH 5.5 and 37°C. Although glucose, fructose, sucrose, starch and dextrin, as carbon sources for growth gave similar mycelial yields, which were higher than those obtained with arabinose, galactose or raffinose, the cells ...

Notes: Conifer Foliage Mass Related to Sapwood Area
Forest Science, 1974Abstract Investigation of 52 trees suggests that foliage mass (kg dry weight) of individual Douglas-fir, noble fir, and ponderosa pine trees can be estimated from regressions on sapwood cross-sectional area (cm²) at dbh (1.3m). Equations are respectively y = 0.072 X -1.34, y = 0.51 X -4.63, and y = 0.043 X +7.13. Correlation coefficients

Sapwood water content of lodgepole pine
2010Breast height sapwood water content fluctuations of lodgepole pine (Pinus contorta var. latifolia Engelm) were studied with the objective of relating them to conducting xylem area, and to environmental and plant variables. Also gamma radiation attenuation was tested as a method for in situ sapwood water content measurement.

Picea abies sapwood width: Variations within and between trees
Scandinavian Journal of Forest Research, 2006This study focused on the amount of sapwood and its variation by means of computed tomographic (CT) imaging. Twenty-four trees were selected from four Norway spruce [Picea abies (L.) Karst.] stands in north-eastern France, varying in age, density and fertility.

Resin Metabolism in the Sapwood of Pinus radiata
Nature, 1963Carbon-14 produced in nuclear explosions was used as a tracer to examine resin metabolism in Pinus radiata. Annual rings of trees were ground and the resin extracted. The C/sup 12/: C/sup 13/ and C/sup 14/ ratio of each sample was determined. Results indicate that all the resin activity is considerably lower than that of the atmosphere at the time the ...

Sapwood and heartwood taper in Scots pine stems
Canadian Journal of Forest Research, 1995The heartwood and sapwood of Pinussylvestris L. were analysed using simultaneous taper models for stem without bark and for heartwood. Sapwood area tapered monotonically from the base to the top of the stem. Below crown base the stem tapered more slowly than in the crown.

Interactions Between Fungi Invading Injured Sapwood of Eucalypts.
Australasian Plant Pathology, 1987The microfungi Cytospora eucalypticola, Paecilomyces variotii and Phialophora bubakii were the organisms most commonly isolated three and six months after mechanical injury to the sapwood of Eucalyptus bancroftii and E. macrorhyncha. While C. eucalypticola and Ph. bubakii were recovered frequently from tissues towards the margins of discoloration above
