A combination of these complementary methods allows a better understanding of the diversity within ironwood (Eusideroxylon zwageri Teijsm. et Binn.), an endangered 'wild' tropical tree species, at molecular and important functional traits. Ironwood belongs to the Lauraceae family. It is one of the most important species for construction wood in Indonesia because it is not vulnerable to termites and other ubiquitous tropical wood-destroying insects and fungi. Due to over-exploitation, populations of ironwood are decreasing and the species is included in the list of threatened tree species. Morphological variability of ironwood has been discussed and studied since the middle of the 19th century. However there is no comprehensive taxonomic assessment to the present time. The variability is mostly recognized by local people based on bark, wood and fruit characteristics. The present study has been conducted to answer whether the variation that is recognized by local people has a genetic basis. AFLPs were chosen as molecular markers best suited for this study due their capacity to estimate genome-wide genetic diversity. Morphological structure assessment was conducted to confirm specific characteristics of each variety. The percentage of polymorphic fragments was 52 %. UPGMA cluster analysis showed that 98 % of individual ironwood samples formed clusters according to their variety as recognized by local people. There was strong correspondence between clusters identified by AFLP analysis and morphological analyses."],["dc.identifier.doi","10.1007/s10722-015-0317-4"],["dc.identifier.isi","000392323200002"],["dc.identifier.scopus","2-s2.0-84941358718"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/65328"],["dc.identifier.url","http://www.scopus.com/inward/record.url?eid=2-s2.0-84941358718&partnerID=MN8TOARS"],["dc.language.iso","en"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.relation.eissn","1573-5109"],["dc.relation.issn","0925-9864"],["dc.title","Linking indigenous knowledge, plant morphology, and molecular differentiation: the case of ironwood (Eusideroxylon zwageri Teijsm. et Binn.)"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dspace.entity.type","Publication"]]

The present investigation was undertaken to examine the effect of soil acidity on rooting patterns of 40-year-old Norway spruce trees by comparing fine and coarse roots among four stands which differed in soil acidity and Mg (and Ca) nutrition. The coarse root systems of four to five 40-year-old Norway spruce trees per stand were manually excavated. The sum of cross sectional area (CSA) at 60 cm soil depth and below of all vertical coarse roots, as a measure of vertical rooting intensity, was strongly reduced with increasing subsoil acidity of the stands. This pattern was confirmed when 5 additional acidic sites were included in the analysis. Fine root biomass in the mineral soil estimated by repeated soil coring was strongly reduced in the heavily acidified stands, but increased in the humic layer. Using ingrowth cores and a screen technique, we showed that the higher root biomass in the humic layer of the more acidic stands was a result of higher root production. Thus, reduced fine root biomass and coarse root CSA in deeper soil layers coincided with increased root growth in the humic layer. Root mineral analysis showed Ca/Al ratios decreased with decreasing base saturation in the deeper mineral soil (20-40 cm). In the top mineral soil, only minor differences were observed among stands. In general, low Ca/Al ratios coincided with low fine root biomass. Calcium/aluminum ratios determined in cortical cell walls using X-ray microanalysis showed a similar pattern as Ca/Al ratios based on analysis of whole fine roots, although the amplitude of changes among the stands was much greater. Aluminum concentrations and Ca/Al ratios in cortical cell walls were at levels found to inhibit root growth of spruce seedlings in laboratory experiments. The data support the idea that Al (or Ca/Al ratios) and acid deposition-induced Mg (and possibly Ca) deficiency are important factors influencing root growth and distribution in acidic forest soils. Changes in carbon partitioning within the root system may contribute to a reduction in deep root growth."],["dc.identifier.doi","10.1023/A:1013305712465"],["dc.identifier.isi","000172861900010"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/16893"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Kluwer Academic Publ"],["dc.relation.issn","0032-079X"],["dc.title","Does soil acidity reduce subsoil rooting in Norway spruce (Picea abies)?"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Radial sound velocities on faulty free discs (Tab. 1) were higher (between 930 m/s and 1013 m/s) than on red rot damaged discs (between 601 m/s and 880 m/s). Therefore an assessing of a damage is limited possible using the sound system (Fig. 14).

The drilling curves of Teredo and Resistograph along the same measuring line of spruce wood ale very similar; they show rots and hollows through low drilling resistances. Both devices are suitable for tree diagnosis (Fig. 3a, b, 4, 8 to 10). The expensive Resistograph 1410 ist excellently suitable for recording the wood conditions along a 40 cm long drill channal if special disadvantages and some experience are involved. The device convinced through its high and exact resolution to detect the borders between early and late wood of wide ring wood (Fig. 13).

Therefore the device is suited for practical use of tree specialists within tree care and wood diagnosis but for scientific research the use is limited.
