title: A note on the precision of estimates of gibberellin concentration from regression lines calculated from bioassay data.
abstract: The method by which the results of biological assays for gibberellinlike substances in plants are presented as "gibberellic acid equivalents" is discussed and a technique for deriving confidence limits for such estimates is referred to. Two different assay methods used to illustrate the technique both showed the relatively wide confidence limits associated with estimates of this kind, following the necessary logrithmic transformation of the data.
