A comparative molecular weight study with particular reference to black wattle tannins

Journal of Polymer Science, 1958
AbstractDetails are given of a further modification to the Ray ebulliometer which permits easy interchange of the Cottrell pump tube. The stability of the apparatus with different pump tubes and pumping conditions was also examined. Molecular weights obtained with the use of two ebulliometers and three solvent systems are compared.

Self-Established Black Wattle Populations in Rwanda: Implications for Nature Conservation

Small-scale Forestry, 2015
Based on empirical evidence from a vegetation survey, this paper investigates the occurrence of self-established populations of black wattle (Acacia mearnsii De Wild.) in various environmental contexts and identifies areas where this species could be allowed to grow as a useful plant.

Effects of storage conditions on chlorophyll content in diploid black wattle (Acacia mearnsii)

The Southern African Forestry Journal, 2006
Black wattle (Acacia mearnsii de Wild) is a commercially important forestry species in South Africa, however, being an exotic it is also seen as an invader of indigenous vegetation. Research into producing a sterile variety is underway and one such route being explored is the production of a polyploidy.

Phytophthora acaciae sp. nov., a new species causing gummosis of black wattle in Brazil

Mycologia, 2019
A new Phytophthora species was found associated with gummosis in black wattle plantations in the subtropical, humid, south of Brazil. The new species Phytophthora acaciae is formally named herein based on phylogenetic and morphological analyses.

Analysis of Black Wattle (Acacia mearnsii De Wild) Bark by Near Infrared Spectroscopy

Holzforschung, 2003
Summary The analysis of two sets of Acacia mearnsii De Wild (Black Wattle) samples by near infrared (NIR) spectroscopy is reported. Set 1 samples were characterised in terms of hot water extractives, Stiasny value and polyflavanoid content. Set 2 samples were characterised by nine different parameters, including tannin content.

Frost tolerance of six seed orchards of Acacia mearnsii (black wattle) and the effect of developmental stage and tree size on frost hardiness

Australian Forestry, 2019
Frost damage is the most important abiotic risk in Acacia mearnsii (black wattle) plantations in South Africa. Current A. mearnsii planting stock cannot tolerate temperatures below −4°C, and therefore there is an urgent need to develop frost-tolerant ...
