Microelements variability in needles of natural populations of Picea omorika

Šumarski list
This is the first study of microelement variability in needles of seven natural populations of Picea omorika (Panč.) Purkyně from Serbia. Seven essential, three usefull, and six toxic microelements were analysed by ICP-Spectrometer. Their range was as follows: Mn > Fe > Zn > Al > Na > B > Cu > Ni > Cr > Cd > Co.

Preparation of extracts from needles of omorika (Picea omorika (Pančić) Purkinye) for peroxidase activity and isoenzyme profile analyses

, 2004
We studied the effect of nonionic detergent Tween 80 in extraction buffer on the activity and isoenzyme pattern of peroxidase from omorika needles. The activity of soluble peroxidases was studied using UV-VIS spectrophotometry and isoelectrofocusing.

Standardizacija istraživanja kariotipova četinjača na primjeru Picea omorika

Šumarski list, 1996
Izrađen je kariotip iz endosperma u razvoju jednog stabla Picea omorika (Panč.) Purk. Deset kromosoma (n=12) je metacentrično, a kromosom IX i XII su submetacentrični. Po položaju centromere, kromosomi X i XI su po izgledu skoro submetacentrični, ali su po definiciji klasificirani kao metacentrični. Ipak na temelju ranijih radova, neki bi autori četiri
