Callus derived from Symphytum officinale L. regenerants was cultured in the presence of various phytohormones. The growth rate of callus was stimulated by all phytohormones at various concentrations. With 1-naphthaleneacetic acid no organ differentiation could be observed. With indole-3-butyric acid at low concentrations only roots were formed, whereas 6-benzylaminopurine, kinetin and zeatin at various concentrations induced either root or shoot formation or the simultaneous regeneration of both. Minor amounts of fructans were formed at high 6-benzylaminopurine-, zeatin- and at all indole-3-acetic acid-concentrations. The concentration of 1-naphthaleneacetic acid had no influence on the fructan content. Highest rates of fructan synthesis occurred at low zeatin-concentrations up to 1.5 mg/l. Only zeatin at all concentrations induced the synthesis of polyfructans, whereas appreciable amounts of oligofructans were formed under the influence of all other phytohormones.
