Deterioration grade of water logged archaeological wood is decisive to select treatments of its conservation and storage, particularly in case of valuable archaeological artefacts. For this purpose archaeological wood of ash (Fraxinus sp.) and oak (Quercus sp.) buried in waterlogged conditions at pr ...

Seasonal structural changes of cambial cells in mature beech (Fagus sylvatica L.) trees growing at elevations of 400 m a.s.l. (lowland) and 1200 m a.s.l. (mountains) are presented on the basis of light (LM) and electron microscopy (TEM). For LM, samples from trees were collected at weekly intervals ...

Fir trees (Abies alba Mill.) in a permanently monitored forest in the Di-naricregion in Slovenia respond to crown damages by distinctly reducing their ring widths. According to transmission electron microscopy (TEM) and UV-microspectrophotometry (UMSP) of cambium-adjacent latewood tracheids of affec ...

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 lignifica ...

Formation and lignification of xylem cells in mature beech (Fagus sylvatica L.) trees growing in a forest site in Slovenia (46° N, 14°40â? E, 400 m a.s.l.) were studied on the cellular and subcellular level. Samples containing the cambial zone and developing xylem were taken from six beech trees eve ...

The commonest approach to studying cambial productivity is conventional light microscopy, which is widely used in wood formation studies. The number of such studies has increased rapidly in the past decade, usually in order to elucidate the relationship between growth and environmental factors. Howe ...

V goslarski delavnici "Atelje Demšar" smo dobili štiri vzorce lesa za godalne loke tujih dobaviteljev, ki so jih označili z imeni (1) pernambuk, (2) konjskomeso, (3) brazil in (4) kačji les. Les smo anatomsko preiskali ter določili vrste: (1) Guilandina echinata (pernambuk, pau brazil, brazil), (2) ...

Opisan je nastanek lesa pri bukvi (Fagus sylvatica), ki smo ga spremljali na vzorcih intaktnih tkiv (lesa, kambijeve cone, skorje). Vzorce smo odvzeli iz odraslih dreves z rastišča na Panški reki pri Ljubljani tekom vegetacijske dobe 2006. Za spremljanje nastanka lesa smo uporabili svetlobno mikrosk ...
