“…Lodgepole pine heartwood contained higher levels of extractives than the sapwood. Similar observations have been reported for shortleaf pine (Posey and Robinson 1969), aspen (Yanchuk etal 1988), Cedrus libani (Hafizoglu 1987), Tilia cordata, Betula verrucosa and Robinia pseudoacacia (Höll and Poschenrieder 1975).…”

“…For different wood species, the values reported in the literature vary from 1.5% to more than 10% of the dry weight (Roll and Poschenrieder 1975;Yildirim and Holmbom 1977 a;Holmbom and Ekman 1978;Torul and Olcay 1984;Hafizoglu 1987;Hafizoglu and Holmbom 1987a;Yanchuk et al 1988;Hafizoglu 1989;Sithole et al 1992). Within a log, great variations have also been observed between bark, sapwood and heartwood (Höll and Poschenrieder 1975;Yanchuk et al 1988;Sithole et al 1992). Our results confirm this radial variation phenomenon.…”

Content and composition of lipophilic extractives from fresh sapwood and heartwood of lodgepole pine (Pinus contorta Dougl.) were investigated by solid-phase extraction, GC and GC-MS techniques. The acetone extractive content in sapwood was 1.9-2.2% of oven dry wood, among which were included 1.1-1.3% triglycerides, 0.02-0.03% free fatty acids, 0.3-0.4% free resin acids, 0.15-0.21% steryl esters and waxes, 0.02 % monoglycerides, and 0.02-0.03 % sterols, fatty alcohols and diglycerides. A considerably higher amount of extractives was present in heartwood, i.e., 10-12%, including 0.6-0.7 % triglycerides, 0.8-1.1% free fatty acids, 4.0-5.6% free resin acids, 0.25-0.33 % steryl esters and waxes, 0.4-0.5% monoglycerides, and 0.08-0.1% sterols, fatty alcohols and diglycerides. The most abundant fatty acid residues in the wood triglycerides were oleic (18:1), linoleic (18:2), linolenic (18.-3) and palmitic (16:0) acids. Together they formed about 85 % and 65 % of the total fatty acid composition in the sapwood and heartwood triglycerides, respectively. Of the steryl esters and waxes, 18:2 was the most dominant residue, followed by 18:3 and 18:1. Twelve major free fatty acids and seven free resin acids were identified and quantified. The abundant free fatty acids in both sapwood and heartwood were 18:2 and 18:1, making up 32-41 % and 24-28 % of the total fatty acid amount, respectively. Palustric acid was the dominant free resin acid, its relative proportion to the total resin acids was 52 % in the outer sapwood and 29% in the inner heartwood. Other major resin acids detected included abietic, isoabietic, dehydroabietic, neoabietic acids.

“…Based on the abundance of lipids in wood, trees have been classified into two groups of storage strategy: fat storing trees (abundant lipid storage) and starch storing trees (scarce lipid storage) (Hillinger et al ., 1996; Hoch et al ., 2003; Hartmann & Trumbore, 2016). However, lipid content has been studied in only a few temperate species because of difficulties related to its quantification and detection (Höll & Poschenrieder, 1975; Fischer & Höll, 1991; Hoch et al ., 2003). Considering the high abundance of parenchyma tissue and low concentrations of starch in tropical trees (Plavcová et al ., 2016), one would expect that lipids may play an important role in the long‐term carbon storage for these tree species; however, the spatial distribution of lipid pools has been described for only a few species (Datta & Kumar, 1987; Nobuchi et al ., 1996).…”

Starch and lipid storage strategies in tropical trees relate to growth and mortality

Summary Non‐structural carbon (NSC) storage (i.e. starch, soluble sugras and lipids) in tree stems play important roles in metabolism and growth. Their spatial distribution in wood may explain species‐specific differences in carbon storage dynamics, growth and survival. However, quantitative information on the spatial distribution of starch and lipids in wood is sparse due to methodological limitations. Here we assessed differences in wood NSC and lipid storage between tropical tree species with different growth and mortality rates and contrasting functional types. We measured starch and soluble sugars in wood cores up to 4 cm deep into the stem using standard chemical quantification methods and histological slices stained with Lugol's iodine. We also detected neutral lipids using histological slices stained with Oil‐Red‐O. The histological method allowed us to group individuals into two categories according to their starch storage strategy: fiber‐storing trees and parenchyma‐storing trees. The first group had a bigger starch pool, slower growth and lower mortality rates than the second group. Lipid storage was found in wood parenchyma in five species and was related to low mortality rates. The quantification of the spatial distribution of starch and lipids in wood improves our understanding of NSC dynamics in trees and reveals additional dimensions of tree growth and survival strategies.

“…On the other hand, according to the literature (Zinkel 1989) the total amount of saturated acids in woods is much less than that of unsaturated ones. However, up to 30 % saturated acids were found in some hardwoods (Holl and Poschenrieder 1975). Figure 1 shows the data of saponifiable components in wood and bark divided into four groups; saturated, unsaturated, triterpene-related acids and others.…”

The bark and wood of an endemic oak species in Turkey, Q. vulcanica, were investigated with regard to main components, phenolics as well as extractives. About 66 % of extract free wood consists of polysaccharides, i.e. cellulose and polyoses. Heartwood was found to be rich in ellagitannins, while in bark proanthocyanidins occurred in larger amounts. Extractives soluble in cyclohexane were divided into saponifiables and neutrals. Among saponifiables saturated acids made up the majority, while sterols and nonsteroidal triterpenes were the predominating compounds of the neutral fraction.
