Composition, distribution and supposed origin of mineral inclusions in sessile oak wood - consequences for microdensitometrical analysis [PDF]

open access: yes, 2007
SEM and light-microscopical observations, supported by chemical microanalysis with an EDXA system, revealed that light-saturated pixels observed in X-ray negatives of sessile oak (Quercus petraea Liebl.) wood were caused by inorganic deposits present ...

Heartwood Formation in Pinus radiata (D. Don) [PDF]

open access: yesNature, 1953
IN a paper which is to be published by the New Zealand Forest Service entitled “Heartwood Formation in Pinus radiata”, it has been shown that conditions which are conducive to the occurrence of physiological drought retard heartwood formation in this species, but that where a deep root system can be developed in an area with adequate rainfall but ...
