Izvleček
V diplomskem delu smo opisali in podrobno raziskali metasekvojo (Metasequoia glyptostroboides Hu et Cheng), saj je vrsta dokaj nova in še precej neraziskana. Poznavanje nove tujerodne vrste in njenih rastnih zahtev je ključno pri odločitvi o njeni uporabi v gospodarske in druge namene. Analizirali smo živi arhiv metasekvoje v drevesnici pri Zadobrovi, ki ga je v letih 1993 in 1994 osnoval Gozdarski inštitut Slovenije iz originalnih semen iz predela na Kitajskem, kjer je bila vrsta opisana (locus classicus). Drevesa v nasadu so bila izmerjena že v letih 2000 in 2006, v letu 2020 pa smo meritve ponovili in najnovejše podatke primerjali s predhodnimi. Ugotovili smo, da je pogostnost reproduktivnih organov, torej storžev in moških cvetov, povezana s premerom in višino drevesa, ne pa z lego v nasadu. Užlebljenost debla ni odvisna od lege v nasadu, je pa močno variabilna in povezana s premerom, prav tako je močno variabilen padec premera z višino. Svetloba oziroma lega v nasadu ni edini dejavnik, ki vpliva na lastnosti posameznega drevesa, temveč je razlog tudi genetska variabilnost med drevesi. Naše ugotovitve iz živega arhiva metasekvoje in v tej nalogi zbrani podatki o vrsti bodo uporabni za morebitno uporabo v gozdu in sajenje metasekvoje pri nas v prihodnosti.

Naslov:Growth and quality of metasequoia (Metasequoia glyptostroboides (Hu et Cheng)) in the live archive at Zadobrova near Ljubljana
Izvleček:
This diploma thesis analyzes the species of Dawn Redwood (Metasequoia glyptostroboides Hu et Cheng) since it is relatively new and has not been researched extensively. The knowledge about non-native tree species and their growth requirements is of key importance in deciding on its usage as a species of economic value. The live archive at Zadobrova, which was established by the Slovenian Forestry Institute in 1993 and 1994, has been analyzed. The trees have been grown from original seeds from an area in China where it was first described (locus classicus). The measurements of all the trees on the plantation were carried out in 2000 and 2006. For the purpose of this diploma, they were taken again in 2020, and the latest data has been analyzed and compared to the previous ones. It has been found that the incidence of reproductive organs, such as cones and male strobili, correlates to the diameter and height of trees, but not to the position in the plantation. The trunks’ ridges do not depend on the position in the plantation; however they vary significantly from one tree to the next. The light and the position in the plantation are not the only factors affecting the characteristics of individual trees; the genotype has an even greater impact. This analysis of the Dawn Redwood live archive and data on the species gathered in this thesis represent significant value and usefulness for potentially using Dawn Redwood in the forest and planting it in Slovenia in the future.
