Cellular and topochemical characteristics of secondary changes in bark tissues of beech (Fagus sylvatica)

Abstract: Anatomical and histometrical investigations were carried out on bark tissues (non-collapsed and collapsed phloem, and periderm) of beech (Fagus sylvatica L.) trees growing at a forest site near Ljubljana, Slovenia (400 m a.s.l.). Secondary changes in bark, especially sclereid formation and lignification, were followed at cellular and sub-cellular levels by light microscopy (LM), UV microspectrophotometry (UMSP), and transmission electron microscopy (TEM). The average width of the whole bark was 5960 mm; non-co… Show more

“…Moreover, the poly-lamellated secondary wall is not an exclusive feature of herbaceous species and appears to have evolved in a variety of taxa. The sclerotic bark fibers of beech (Fagus sylvatica) have thick cell walls with numerous individual layers irregularly arranged [24]. Tension wood of Laetia procera (Poepp.)…”

“…1). Weighting the specific gravities of inner and outer beech bark according to their relative respective thickness of 93 and 7% (Prislan et al 2011), a calculated specific gravity of 0.58 is obtained fitting with the present experimental mean specific gravity for whole beech bark. Dimitri (1968) observed, that oven-dry density and thickness of beech bark are negatively correlated.…”

“…This result could be explained by (1) the higher specific gravity of outer beech bark (Fig. 1) and (2) the fact that the increase in beech bark thickness by secondary growth is mainly due to phloem increment (Holdheide 1951;Prislan et al 2011).…”

“…Dilatation is often followed by a common secondary change in bark: the development of sclereids. Sclereids are isodiametric or longitudinally oriented cells that develop through the swelling of parenchyma cells and the deposition of thick secondary walls (Prislan et al 2012). Although sclereids may also develop from early cambial derivatives (Esau 1969;Angyalossy et al 2016), their development is almost always associated with dilatation growth (Evert 2006).…”
