“…The secondary chemistry of Betula is dominated by phenolic compounds, including low molecular weight phenolics, tannins, and lignin (Julkunen-Tiitto et al, 1996;Ossipov et al, 1996;Mämmelä, 2001;Laitinen et al, 2004;Mattson et al, 2005), but how these chemicals vary in the phloem of mature paper birch and European white birch is not known. Therefore, as a follow-up to the commongarden study of Nielsen et al (2011) that documented greater resistance to BBB in paper birch relative to European white birch, we initiated a study at the same site with the goal of elucidating potential mechanisms underlying variation in resistance.…”

Inter- and Intra-Specific Variation in Stem Phloem Phenolics of Paper Birch (Betula papyrifera) and European White Birch (Betula pendula)

et al. 2011

Outbreaks of bronze birch borer (BBB) (Agrilus anxius), a wood-boring beetle endemic to North America, have been associated with widespread mortality of birch (Betula spp.). There is substantial inter- and intra-specific variation in birch resistance to BBB. Species endemic to North America, such as paper birch (B. papyrifera), have coevolved with BBB and are more resistant than European and Asian birch species, such as European white birch (B. pendula), which lack an evolutionary history with BBB. Borer larvae feed on stem phloem tissue. Therefore, in search of potential resistance mechanisms against BBB, we compared the constitutive phenolic profile of stem phloem tissue of paper birch with that of European white birch. We also analyzed intraspecific variation in phenolic composition among clones and/or half-siblings of both species. Three phenolics (coumaroylquinic acid, betuloside pentoside A, and a diarylheptanoid hexoside) were detected only in paper birch, and concentrations of six other phenolics were significantly higher in paper birch. These differences may contribute to the high resistance of paper birch to BBB relative to European white birch. There was significant intraspecific variation in four of 17 phenolics found in paper birch and in five of 14 found in European white birch, but clones and half-siblings within each species could not be distinguished by phenolic composition using multivariate analysis.

“…The hydroxybenzoic acids, protocatechuic (peak 2), vanillic (5) and syringic (8), the hydroxybenzoic aldehydes protocatechuic (3), vanillic (7) and syringic (10), the hydroxycinnamic acid ferulic (12), the hydroxycinnamic aldehydes coniferylic (14), and sinapic (17), as well as hydroxytyrosol (1) and tyrosol (4) were identified by comparison of their retention times, as well as comparing UV/Vis and mass spectra with those of pure commercial standards. These compounds were frequently found in phenolic extracts from other woods for cooperage, [8][9][10]16] with the exception of hydroxytyrosol and tyrosol.…”

“…Mammela [14] found some phenolic compounds in ash (F. excelsior) wood dust, but only hexahydroxydiphenoil (HHDP)-glucose, tetragalloyl glucose and digalloyl-bis-HHDP-glucose were suggested as possible identifications. On the other hand, Windeisen and Wegener [15] tentatively identified by GC-MS the lignan syringaresinol in thermally modified F. excelsior wood (200 C for 4 h in a nitrogen atmosphere and under pressure), in order to increase the natural durability of this wood.…”

The phenolic composition of heartwood extracts from Fraxinus excelsior L. and F. americana L., both before and after toasting in cooperage, was studied using LC-DAD/ESI-MS/MS. Low-molecular weight (LMW) phenolic compounds, secoiridoids, phenylethanoid glycosides, dilignols and oligolignols compounds were detected, and 48 were identified, or tentatively characterized, on the basis of their retention time, UV/Vis and MS spectra, and MS fragmentation patterns. Some LMW phenolic compounds like protocatechuic acid and aldehyde, hydroxytyrosol and tyrosol, were unlike to those for oak wood, while ellagic and gallic acid were not found. The toasting of wood resulted in a progressive increase in lignin degradation products with regard to toasting intensity. The levels of some of these compounds in medium-toasted ash woods were much higher than those normally detected in toasted oak, highlighting vanillin levels, thus a more pronounced vanilla character can be expected when using toasted ash wood in the aging wines. Moreover, in seasoned wood, we found a great variety of phenolic compounds which had not been found in oak wood, especially oleuropein, ligstroside and olivil, along with verbascoside and isoverbascoside in F. excelsior, and oleoside in F. americana. Toasting mainly provoked their degradation, thus in medium-toasted wood, only four of them were detected. This resulted in a minor differentiation between toasted ash and oak woods. The absence of tannins in ash wood, which are very important in oak wood, is another peculiar characteristic that should be taken into account when considering its use in cooperage.

“…However, it is unclear how tree species influence the chemical properties of DOM and especially of POM in TF, SF and FF leachates and hence how they subsequently affect soil processes by varying chemical compositions and associated functionalities. In this context, beech trees potentially exhibit the highest amounts of phenolics in leaves (Bussotti et al, 1998), bark (Dübeler et al, 1997), wood (Mämmelä, 2001) and roots (Weissen and Van Praag, 1991) compared to co-occurring species. Phenolic compounds released from living or dead plant material have been shown to function as allelochemicals, affecting associated species (Rice, 1984;Wardle et al, 1998).…”

Properties of dissolved and total organic matter in throughfall, stemflow and forest floor leachate of central European forests

et al. 2015

Abstract. We present the first investigation of the composition of dissolved organic matter (DOM) compared to total organic matter (TOM, consisting of DOM, < 0.45 µm and particulate organic matter 0.45 µm < POM < 500 µm) in throughfall, stemflow and forest floor leachate of common beech (Fagus sylvatica L.) and Norway spruce (Picea abies (L.) H. Karst.) forests using solid-state 13 C nuclear magnetic resonance (NMR) spectroscopy. We hypothesized that the composition and properties of organic matter (OM) in forest ecosystem water samples differ between DOM and TOM and between the two tree species.The 13 C NMR results, derived from 21 samples, point to pronounced differences in the composition of DOM and TOM in throughfall solution at the beech sites, with TOM exhibiting higher relative intensities for the alkyl C region, which represents aliphatic C from less decomposed organic material compared to DOM. Furthermore, TOM shows lower intensities for lignin-derived and aromatic C of the aryl C region resulting in lower aromaticity indices and a diminished degree of humification. Across the ecosystem compartments, differences in the structural composition of DOM and TOM under beech lessened in the following order: throughfall > stemflow ≈ forest floor leachate.In contrast to the broadleaved sites, differences between DOM and TOM in throughfall solution under spruce were less pronounced and spectra were, overall, dominated by the alkyl C region, representing aliphatic C. Explanations of the reported results might be substantiated in differences in tree species-specific structural effects, leaching characteristics or differences in the microbial community of the tree species' phyllosphere and cortisphere. However, the fact that throughfall DOM under beech showed the highest intensities of recalcitrant aromatic and phenolic C among all samples analysed likely points to a high allelopathic potential of beech trees negatively affecting other organisms and hence ecosystem processes and functions.
