Preživetvena sposobnost listavcev na posekah v sestojih črnega bora (Pinus nigra Arnold) na Krasu : diplomsko delo - visokošolski strokovni študij - 1. stopnja

Lumbar, Andrej (author), Brus, Robert (mentor), Jarni, Kristjan (co-mentor)

V diplomski nalogi se je ugotavljalo, katere drevesne vrste bi bile primerne za premene malodonosnih kraških gozdov. V prvem letu po saditvi so bili preverjeni deleži preživetja sadik, višina sadik ter njihov prirastek in vitalnost. V bližini Divače je bilo v letu 2012 osnovanih 6 raziskovalnih ploskev v velikosti 45 % 80 m. Poizkusno so posadili sadike šestih drevesnih vrst: navadnega koprivovca (Celtis australis L.), gradna (Quercus petraea (Matt.) Liebl), navadne bukve (Fagus sylvatica L.), divje češnje (Prunus avium L.), navadnega oreha (Juglans regia L.) ter gorskega javorja (Acer pseudoplatanus L.). Največji delež preživetja na vseh šestih ploskvah se je pokazal pri divji češnji (95 %), navadnem orehu (92 %) in pri navadnem koprivovcu (91 %). Slabše sta se izkazala navadna bukev in gorski javor, saj je bil delež preživetja v primerjavi z uspešnimi drevesnimi vrstami tudi za 20 % manjši. Velik vpliv na preživetje, prirastek, višino in vitalnost sadik sta imela kakovost sadik in rastišče.

Abstract

This thesis presents that certain parameters have been used to determine which tree species would be suitable for transformation of low productivity karst forests. In the first year after planting were checked the survival rates of seedlings, seedling height, and their increment and vitality. In the year 2012 six research plots of sizes 45 % 80 m were based near the town Divača. Experimentally, they planted seedlings of six tree species: European nettle tree (Celtis australis L.), sessile oak (Quercus petraea (Matt.) Liebl.), common beech (Fagus sylvatica L.), wild cherry (Prunus avium L.), common walnut (Juglans regia L.) and sycamore (Acer pseudoplatanus L.). The largest proportion of survival at all six plots was found with wild cherry (95%), common walnut (92 %) and European nettle tree (91%). Common beech and sycamore showed a worse growth, since the survival rate compared with successful tree species was 20 % lower. The quality of seedlings and the site quality had a major impact on survival, increment, height and vitality of seedlings.
