Chromium-51 Distribution in Tissues and Extracts of Leptospermum scoparium

Chromium-51 Distribution in Tissues and Extracts of Leptospermum scoparium

Leptospermum scoparium plants cultured in solutions containing Na251CrO4 accumulated most of the absorbed radioactivity in the roots. About one third of the root radioactivity was soluble in 80% ethanol in the form of three 51Cr-complexes, the predominant one being identified as trioxalatochromate (...

Zusammenfassung:Leptospermum scoparium plants cultured in solutions containing Na251CrO4 accumulated most of the absorbed radioactivity in the roots. About one third of the root radioactivity was soluble in 80% ethanol in the form of three 51Cr-complexes, the predominant one being identified as trioxalatochromate (III) ion. These complexes were also present in stem and leaf extracts. 51Cr distribution was examined in various chemical fractions; protein and nucleic acids were especially low in radioactivity.
