    Summary
    (Evolution of the auxin-oxidase and peroxidase activity during the spinach's photo-periodic induction and sexualisation) Protein extracts, prepared from spinach leaves, are analysed after a gel chromatography on Sephadex G-100 and SE-Sephadex C-50. The photoperiodic induction seems related with a fall of the auxin-oxidase and peroxidase activities we observe a change in the isozyme number and pattern. The female plants have more isozymes, but the enzymatic activity is higher in the male plants. The destruction of the indole-3-acetic acid, in spinach, is not strictly related to the peroxidases
