Vsebnost celokupnih fenolov v lesu mehansko poškodovanih bukev (Fagus sylvatica L.) : diplomsko delo - univerzitetni študij = Content of total phenols in wood of mechanically wounded beech (Fagus sylvatica L.) : graduation thesis - university studiesGaber, KarolinaV lesu 2 preučevanih bukev ( Fagus sylvatica L . ), posekanih v urbanem okolju na JZ pobočju Rožnika v Ljubljani, smo ugotovili vsebnost celokupnih fenolov v ksilemskih tkivih, nastalih kot odziv na ... mehansko poškodbo. Raziskali smo, katera poranitvena tkiva vsebujejo večji delež celokupnih fenolov. Pripravljene vzorce smo najprej ekstrahirali v vodni raztopini 80 % metanola. Delež celokupnih fenolov smo določili spektrofotometrično po Folin-Ciocalteau-jevi metodi. Ugotovili smo, da se vsebnost celokupnih fenolov v tkivih razlikuje znotraj drevesa in med drevesoma. Pri 1. drevesu je bila vsebnost celokupnih fenolov največja v lesu reakcijske cone (283,92 mg/L), ki je razmejevala prizadeto in zdravo tkivo. V diskoloriranem lesu je bila vsebnost celokupnih fenolov najmanjša (36,39 mg/L). Povečana vsebnost celokupnih fenolov v lesu reakcijske cone je najverjetneje prispevala h kompartmentalizacijski učinkovitosti teh tkiv.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [K.
