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

Effects of Bioturbation by Earthworms on Litter Flammability in Young and Mature Afforested Stands

Fire
The quantity, quality, and accumulation rate of plant litter play a key role in forest floor flammability and, by extension, fire regimes. The varying foliage properties of different tree species also determine litter’s decomposition and its accumulation
