Abstract The individual free amino‐acids of the leaf and stem tissues of two related tropical pasture grasses— Brachiari ruziziensis and Setaria sphacelata —have been quantitatively determined in 17 successive weekly cuttings from the early seedling to the flowering stages, by a paper‐chromatographic DNP method. The observed differences in the respective amino‐acid patterns of the two species are insufficient to account for the relatively greater accumulation of ammonium‐N, during the early growth period, in S. sphacelata which has been previously reported.
