Abstract

Callus tissues were derived from the stem of healthy tomato plants Lycopersicum esculentumMill ev Průhonické and of plants infected with potato witches broom—a disease caused by mycoplasma Callus cultures were established on modified fully synthetic media described byMorel 1948 and byMurashige andSkoog 1962 Callus cultures obtained from diseased plants were grown and subcultured on both media growth in primary isolates from healthy plants took place on the Murashige and Skoog medium only Growth of callus tissue derived from diseased plants was more vigorous even after several subcultivations in comparison with callus tissues isolated from healthy plants Variations in the morphology in these callus cultures were not noted Callus cells of diseased plants varied in size they were about 50 larger than those from healthy ones Implantation of primary and subcultivated callus tissues into tomato stems of healthy plants did not show any symptoms of infection on test plantsZe stonku rajčete Lycopersicum esculentumMill cv Průhonické jednak ze zdravé rostliny jednak z rostliny nakažené mykoplasmosou—metlovitostí bramboru byly získány kalusy které byly kultivovány na syntetických půdách a to na modifikované živné půdě podle Morela a podle Murashigeho a Skooga Z nemocné rostliny se podařilo získat kalus na obou půdách a jeho pletivo bylo dále úspěšně subkultivováno tato izolace pletiva ze zdravé rostliny se však podařila pouze na modifikované půdě Murashigeho a Skooga Kalus izolovaný z nemocné rostliny vykazoval proti kalusu izolovanému ze zdravé rostliny intenzi nější růst a to i po několikanásobné subkultivaci Morfologicky ani anatomicky se obě pletiva podstatně nelišila avšak buňky kalusového pletiva izolovaného z nemocné rostliny byly průměrně asi o 50 větší Implantací primárního nebo subkultivovaného kalusového pletiva do stonků zdravých rajčat se nepodařilo testovací rostliny nakazit
