Physiological And Biochemical

A significant limitation of callus tissue growth was noted in <i>Nicotiana tabacum</i> L. cultured in vitro under the influence of morphactin IT 3233 applied in 10 - 40 mg/dm<sup>3</sup> concentrations. Growth inhibition was associated with an increase in dry mass content and the contribution of protein N to the nitrogen, pool. Tumour tissue of tobacco under the same conditions reacted weaker to morphactin. Growth limitation reached 25 per cent as compared with the control, dry mass and nitrogen compounds content showed only slight variations. It is supposed that the different sensitivity of both types of tissues to morphactin is connected with their different hormonal metabolism.

Physiological And Biochemical

It was found that the inhibition of callus tissue growth in <i>Nicotiana tabacum</i> L. cultured <i>in vitro</i> 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. Respiratory activity of these tissues is also lowered. Tumour tissues, on the other hand, show only light changes in the parameters studied. It would seem that morphactin depresses a metabolic activity in the callus tissues, and probably causes deposition of a, large quantity of metabolically inactive proteins.
