RESEARCHES CONCERNING THE DETERMINATION OF MINERAL COMPOSITION OF NORWAY SPRUCE EMBRIONS THROUGH QUANTITATIVE ELECTRONMICROSCOPY
2003
Ionita L.
Through determination of mineral composition we can establish if a certain provenance was cultivated on a certain soil and so being able to discern between provenances. The method used was SEMQuant (quantitative scanning electronmicroscopy) and the quantitative method was ZAF. We used 5 Norway spruce provenances and we where able to establish the mineral spectrum for each of them. The analyses showed the presence of both normal elements and toxic ones in the embryos. The presence or absence of an element and its concentration was a criterion for discerning between provenances. Keywords: elctronmicroscopy, markers, mineral analysis, Norway spruce.
