We present xylem formation in Norway spruce (Picea abies (L.) Karst.) in 2015 at Panška reka, near Ljubljana, Slovenia (ca. 46°00'N, 14°40'E, 400 m a.s.l.) with a temperate climate. The research was a part of a long-term project, which involves different sites and tree species. We measured the widths of cambium and the formation of xylem growth rings with differentiating cells in postcambial (PC) and secondary wall formation (SW) phases, and mature cells (MT). The results for 2015 were compared with those for previous years (2009%2011) in the same species and site, and with the published data from wood formation studies in conifers from all over Europe. The latter were used in two-factor regression models which confirmed the effects of latitude and altitude on the critical dates of onset, end, and duration of xylem production. The models thus helped us to predict/reconstruct phenology of wood formation in conifers in Europe

Abstract

Študija prikazuje nastajanje lesa smreke (Picea abies (L.) Karst.) v rastni sezoni 2015 na rastišču Panška reka v bližini Ljubljane (pribl. 46°00'N, 14°40'E, 400 m n.v.). Raziskava je del večletnega projekta spremljanja nastajanja lesa več drevesnih vrst na različnih rastiščih. V okviru raziskave smo spremljali širino kambijeve cone ter nastajajoče branike lesa, kjer smo ločili celice v fazah postkambialne rasti (PC) in nastajanja sekundarne celične stene (SW) ter zrele (MT) celice. Rezultate smo primerjali z ugotovitvami študije, opravljene na smreki z istega rastišča v rastnih sezonah 2009%2011 ter s podatki, objavljenimi za več vrst iglavcev z različnih rastišč po Evropi. Primerjave smo uporabili za izdelavo regresijskih modelov z dvema neodvisnima spremenljivkama. Modeli so potrdili vpliv zemljepisne širine in nadmorske višine na kritične datume začetka in konca ter na trajanje nastajanja lesa. Modeli so omogočili rekonstrukcijo fenologije nastajanja lesa iglavcev po Evropi
