The addition of morphactin IT 3233 in 1-40 mg/dm3 concentrations to the medium inhibited the growth in vitro of normal and tumourous tobacco calluses. The auxin activity (estimated by the Avena coleoptile straight growth test) of the acid ether extra

The morphactins under examination blocked the growth of tobacco callus tis-sues at as low concentrations as l mg/dm3 (IT 3456) and 10 mg/dm3 (IT 3233). The growth inhibition was accompanied by an increase in dry matter content. An increment in total

It was found that the inhibition of callus tissue growth in Nicotiana tabacum L. cultured in vitro by the application of morphactin IT 3233 is associated with a rise of the protein level in spite of a 50 per cent depression of its synthesis. Respirat

IAA oxidase activity in callus and tumour tissue of tobacco subjected to the action of morphactin IT 3233 for shorter and longer periods was determined. Control tumour tissue shows an activity higher by about 40 per cent as compared with that of call

An active alanine transaminase was found both in callus and tumour tissues of tobacco. The enzyme is more active in the latter tissue, and the reaction balance is strongly shifted towards alanine production, while in callus tissue towards glutamic ac

A significant limitation of callus tissue growth was noted in Nicotiana tabacum L. cultured in vitro under the influence of morphactin IT 3233 applied in 10 - 40 mg/dm3 concentrations. Growth inhibition was associated with an increase in dry mass con

In normal and tumourous calluses of sunflower and tobacco the level of extractable auxins was determined by Avena coleoptile straight growth test. Auxin activity was detected practically in two zones: I - at position with Rf 0.2-0.4 and II - at posit
