Količina lignina v arheološki jesenovini : diplomsko delo (univerzitetni študij) = Lignin content in archaeological ash wood : graduation thesis (university studies)Pintar, VesnaRaziskali smo količino lignina v vzorcih arheološkega lesa jesena (Fraximus sp.) iz 4 eneolitskih koliščarskih naselbin na Ljubljanskem barju, ki so se razlikovale po starosti in nahajališču lesa. ... Les iz kolišč Parte-Iščica in Založnica je bil star približno 4500 let, iz Spodnjega mostišča 1 in 2 ter Hočevarice pa približno 5500 let. Koli so se ohranili pod zemljo (Založnica, Hočevarica) ali v vodi (Parte-Iščica, Spodnje mostišče). Količino lignina smo za primerjavo določili tudi v recentni jesenovini. Za določanje vsebnosti lignina smo uporabili gravimetrično metodo po Klasonu kot jo predpisujeta standarda TAPPI 13m-54, iz leta 1983 in 1992. Največ lignina je vseboval les iz kolišča Založnice (70,7%), nato Parte-Iščice (69,0%) in Spodnjega mostišča (68,4%), najmanj pa les iz Hočevarice (65,1%). Delež lignina v arheološkem lesu je bil v povprečju 2,5 krat večji kot v recentni jesenovini, ki je vsebovala 25,7% lignina. Delež lignina pri lesu iz kolišč starih 5500 let je bil nekoliko nižji kot pri lesu iz obeh mlajših kolišč. Razlike v vsebnosti lignina pri lesu, ki je bil približno iste starosti, vendar ohranjen v različnih okoljih, niso bile statistično značilne.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [V.
