Acacia mearnsii (black wattle).
2021Abstract A fast-growing, nitrogen-fixing tree adapted to a wide range of sites from the temperate and subtropical lowlands to tropical highlands. It yields bark extractives high in quality tannin, paper pulp, cellulose for rayon, charcoal, and fuelwood. The use of A.

Multiplication of juvenile black wattle by microcuttings
Plant Cell, Tissue and Organ Culture, 2001The influence of mineral formulation, growth regulators and activated charcoal on micropropagation of juvenile black wattle (Acacia mearnsii) was studied. Nodal segments of one-month-old seedlings were used as starting material. After 30 to 45 days, they developed into shoots, which were divided into microcuttings and transferred to fresh media.

The Latin Name of the Black Wattle
Kew Bulletin, 1960The name A. decurrens var. mollis was published by Lindley in Bot. Reg. 5, t. 371 (1819), with a good description and plate. Mr. E. J. H. Corner kindly informs us that there is no specimen of this in the Lindley Herbarium at Cambridge University, nor has authentic material come to light elsewhere.

Black wattle tannin as a zinc phosphating coating sealer
Surface and Interface Analysis, 2013This paper reports an investigation into the use of condensed black wattle tannin as an environmental friendly sealer after zinc phosphating of carbon steel. In order to verify the sealer efficiency against corrosion, electrochemical impedance spectroscopy, potentiodynamic polarisation and salt spray tests were performed.

Diseases of Black Wattle in South Africa—A Review
South African Forestry Journal, 1995SYNOPSIS Black wattle (Acacia mearnsii) is an economically important plantation tree in many parts of the world. In South Africa it is mainly planted for the production of tannins and high quality pulp. Wattle trees are affected by various diseases, some of which have led to devastating losses and the termination of planting programmes.

International Journal of Biological Macromolecules, 2023
This work proposed new black-wattle tannin/kraft lignin H3PO4-activated carbon xerogels as sustainable and efficient adsorbents. The precursors were chosen based on their eco-friendly and cost-effective nature, aiming to achieve adsorbents with high adsorption capacities.

Site Evaluation in Black Wattle with Special Reference to Soil Factors
South African Forestry Journal, 1991SUMMARY Together with climate, soil characteristics are the most important factors affecting tree growth. However, the attempts in many site evaluation studies to establish a direct relationship between soil factors and tree growth have not been very successful, the exception being soil depth which has been shown to be of general significance ...

A comparative molecular weight study with particular reference to black wattle tannins
Journal of Polymer Science, 1958AbstractDetails 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, 2015Based 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.
