An investigation into more rapid procedures for preparing leaf-tissue samples for analysis

Abstract

Several rapid ashing procedures for the analysis of leaf-tissue samples to determine their inorganic constituents are described. Various types of sample were extracted with different acid mixtures or ashed for short periods under different conditions and their constituents were then determined by means of atomic absorption. The values obtained by these methods were compared with those obtained by use of standard procedures.

A general procedure for the rapid ashing of plant material, which is suitable for the determination of a number of inorganic constituents, is described in detail.
