Abstract:Bela murva (Morus alba L.) izvira iz vzhodne Azije, v Evropo so jo prinesli v 16. stoletju. Približno od druge polovice 17. st. do konca II. svetovne vojne so murve v Vipavski dolini zasajali z namenom prehrane sviloprejk. Namen diplomskega dela je bil preučiti razlike v morfometričnih lastnostih listov različnih genotipov murv, ki smo jih vzorčili v Vipavski dolini. Vzorčili smo peti do sedmi list ne glede na ekspozicijo. Merili smo površino, dolžino peclja, dolžino lista, širino lista, levo in desno širino glede na bazalno žilo, dolžino leve bazalne žile in dolžino desne bazalne žile. Ugotovili smo, da gojitvena rez vpliva na velikost listov in tudi na izraženo heterofilijo. Pearsonov koeficient korelacije med rezjo in merjenimi parametri je pokazal močno korelativno povezanost. Najvišje srednje vrednosti pri vseh merjenih parametrih smo izmerili pri drevesih, ki so bila obrezana vsako leto in najmanjše srednje vrednosti pri drevesih, ki niso bila obrezana. Na podlagi rezultatov lahko zaključimo, da rez vpliva na velikost listov, saj drevo vzpostavlja ravnovesje med podzemnim in nadzemnim delom in si z večanjem površine zagotavlja zadostno količino fotoasimilatov za rast in razvoj.

Title:Morphological variation of leaves of old local mulberry genotypes in Vipava region
Abstract:White mulberry (Morus alba L.) originates from East Asia. To Europe it was introduced in the 16th century. From the second half of the 17th century until the end of II. World War mulberries were planted in Vipava valley for the purpose of sericulture. The aim of presented diploma thesis was to examine differences in the morphometric characteristics of leaves of different mulberry genotypes sampled in the Vipava Valley. We sampled the fifth to seventh leaf from the apex irrespective of the exposition. The leaf area, peduncle length, leaf length, leaf width, the right and the left width from the rachis, the length of the left basal vein and the length of the right basal vein. Pruning affects the size of the leaves and also the expression of heterophylly. Pearson correlation coefficient between pruning and measured parameters indicated a strong correlative relationship. The highest mean values of all measured parameters were analyzed for trees that were trimmed every year and the lowest mean value were determined for trees that remained uncut. Based on the results we can conclude that the pruning affects the size of the leaves as the tree strikes a balance between roots and canopy. By increasing the leaf surface area the tree provides itself a sufficient amount of photoassimilates for growth and development.
