THE EFFECT OF ALUMINUM ON CYTOKININS IN THE MYCELIA OF AMANITA-MUSCARIA

High performance liquid chromatography analysis of immunoaffinity-puri fied extracts of mycelia of Amanita muscaria, and the Amaranthus bioas say of the eluted fractions, revealed the following seven cytokinins: zeatin, zeatin riboside, zeatin N-9-glucoside, dihydrozeatin, dihydroz eatin riboside, isopentenyl adenine, and isopentenyl adenosine, The de creased growth of aluminum-treated mycelia correlated with a 35% decre ase in the total amount of the cytokinins, Among individual cytokinins , zeatin was the most affected, exhibiting a reduction of about 90%. T he results are compared with previous investigations of aluminum effec ts on cytokinins in the mycelia of Lactarius piperatus, whose growth i s stimulated by aluminum.
