“…The production of allelochemicals by A. dealbata in the introduced range is well documented (Carballeira and Reigosa, 1999;Lorenzo et al, 2008). Although we do not know the chemical composition of the exudates and leachates of A. dealbata well, the presence of sterols, p-hydroxycinnamic acids, chalcone glycosides, iminoacids and triterpenes has been published (Freire et al, 2005;Freire et al, 2007;Imperato, 1982;Kunii et al, 1996;Pereira et al, 1996), some of them well known as allelochemicals.…”

“…However, there are also some harmful substances (Seigler, 2002), among them complex phenolic compounds (Seigler, 2003). In A. dealbata there can be found iminoacids (Kunii et al, 1996), chalcone glycosides (Imperato, 1982), triterpenes (Pereira et al, 1996), sterols (Freire et al, 2005) and p-Hydroxycinnamic acids (especially caffeic acid esters with long-chain fatty alcohols, Freire et al, 2007), some of which can act as allelochemicals . When A. dealbata was introduced into NW Spain, it brought "novel weapons" (Callaway and Aschehoug, 2000) that interfere with native species (Carballeira and Reigosa, 1999;Lorenzo et al, 2008).…”

The genus Acacia as invader: the characteristic case of Acacia dealbata Link in Europe

Abstract• We review current knowledge about the biology of the genus Acacia, and Acacia dealbata Link (silver wattle) in particular, as an invader in Europe, focusing on (i) the biology of the genus Acacia; (ii) biological attributes that are important for the invasiveness of the genus and A. dealbata; (iii) possible hypotheses for the invasion success; and (iv) control methods.• Several Australian wattles have been recorded as naturalized in Europe. Acacia has attained pest proportions in certain habitats and protected sites (notably coastal dunes, river courses, natural parks and biosphere reserves).• The spread of Acacia dealbata seems to be assisted by human interference such as soil disturbance and severe fires. The biological attributes favoring invasion by A. dealbata include tolerance of changing soil conditions, the ability to take advantage of environmental disturbance, phenotypic plasticity, vegetative reproduction, fire tolerance and allelopathic potential.• Different hypotheses explaining invasiveness and transition between invasion steps related to biological attributes as the key factor for A. dealbata invasion are discussed. Effects on the biodiversity of native flora are little understood and studies of suppression of autochthonous species are needed. It is desirable that further studies comparing Acacia at field sites in their native and exotic range should be done.• Understanding the biology of invasive wattles in Europe is the first step to an effective control method. Studies comparing plant invaders at field sites in their native and invaded areas seem to be most appropriate in order to be able to attack the most vulnerable stages.

“…2020, 21, 1814 2 of 16 Notwithstanding, the invading behavior of A. dealbata turned it into a major concern for the forestry sector, particularly for the pulp and paper industry and the respective Eucalyptus species plantations [14]. Actually, A. dealbata has been considered a residue for pulp industry, being left in the forest or used essentially an energy source [9,15,16]. Thus, the valorization of this species for high value applications is of major importance for countries where pulp and paper industry has a high impact.…”

“…So far, only a few studies have been focused on searching innovative ways to add value to A. dealbata, demonstrating that it is particularly interesting as a source of high-value compounds [8,15,17]. Nevertheless, these studies have only focused on specific families [8,15], specific tree parts [17], or even neglected the quantification of the compounds detected [8].…”

Acacia dealbata biomass, either from forest exploitation or from the management of invasive species, can be a strategic topic, namely as a source of high-value compounds. In this sense, the present study aimed at the detailed characterization of the lipophilic components of different morphological parts of A. dealbata and the evaluation of their cytotoxicity in cells representative of different mammals' tissues. The chemical composition of lipophilic extracts from A. dealbata bark, wood and leaves was evaluated using gas chromatography-mass spectrometry (GC-MS). Terpenic compounds (representing 50.2%-68.4% of the total bark and leaves extracts, respectively) and sterols (60.5% of the total wood extract) were the main components of these extracts. Other constituents, such as fatty acids, long-chain aliphatic alcohols, monoglycerides, and aromatic compounds were also detected in the studied extracts. All the extracts showed low or no cytotoxicity in the different cells tested, demonstrating their safety profile and highlighting their potential to be used in nutraceutical or pharmaceutical applications. This study is therefore an important contribution to the valorization of A. dealbata, demonstrating the potential of this species as a source of high value lipophilic compounds.

“…Qualitatively, the bark of many Acacia species, including A. dealbata , is rich in complex phenolic compounds (condensed tannins) and polysaccharides (gums) . The bark of A. dealbata is also an abundant source of sterols such as spinasterol, dihydrospinasterol and stigmasterol, as well as of high amounts of caffeic acid esters with long chain fatty alcohols or p ‐hydroxycinnamic acid esters . Furthermore, the bark can be a source of phenols, flavonoids, and tannins with anti‐inflammatory and anti‐oxidant activities for health supplements and foods, suggesting the low toxicity of its constituents.…”

BACKGROUND Acacia dealbata Link is an invasive plant worldwide. Finding potential uses for its waste that contribute to controling its spread and result in benefits for agriculture has recently become a new topic of research. This study aimed to evaluate the potential biostimulant effect of bark extract derived from the management of A. dealbata (0, 450 or 900 ppm) on onion plants growing under stressful conditions, such as in soils treated with saline solutions (0, 60 or 120 mmol L−1 NaCl) and with reduced irrigation (100%, 50% or 25%). RESULTS A. dealbata Link bark extract significantly increased height as well as leaf, root and total biomass of plants in soils irrigated with NaCl solution (120 mmol L−1). These plants also had a higher content of Cl in roots, but a lower content of P in leaves and of K in bulbs. The 450 ppm bark treatment additionally increased the protein content in leaves and decreased the Na and Mg content in bulbs and bulbs and roots, respectively. The bark extract also increased the sugar content in plants under saline conditions. However, the effect of bark extract was negligible on plants that grew under drought stress. CONCLUSION Results revealed that the bark extract might attenuate stress effects in plants growing at high salinity levels, probably by increasing their sugar and protein content and via the accumulation of ions in the roots. Although additional experiments are required, we suggest that the bark extract of A. dealbata has potential applications in agriculture concerned with biostimulant formulations. © 2019 Society of Chemical Industry
