Abstract

An extraction method is described for quantitatively
determining Mg, K, Na, Zn, and Mn in
plant tissues. The tissue is extracted with 2% trichloroacetic
acid and the elements are determined
on the filtrate by atomic absorption spectrophotometry.
Results compare favorably with
those determined after wet ashing with nitric and
perchloric acids. In addition, trichloroacetic acid
extracts the same fraction of P as does acetic
acid and quantitatively extracts total Ca from
plant tissues not high in oxalate.
