| Abstract: | The surface potantial (Es), lipids content and the contents of main phospholipid fractions, i.e. PC, PE and PI, in callus from the mesocotyl part of mature embryo of winter wheat var. Grana have been estimated. Callus was obtained by the endosperm supported induction. Measurements were repeated during callus vegetation at 25 °C for 35 days or at 5 °C for over 50 days. The transfer of callus to cold caused a temperature stress and as result Es decreased almost twice. However, during further growth of callus at low temperature a nearly linear increase of the potential took place. During this time small green areas with densely packed cells appeared. The surface potential of the centres was different from that measured in the non-differentiated part of callus. Moreover, this potential was entirely independent of the temperature and time of callus growth. Some evidences indicating that the differences in the surface potential of callus cells precede the appearance of visible differentiating structures were also obtained. At 5 °C the content of main phospholipid fractions initially grew and then their quantities distinctly diminished. During callus growth at 25 °C remarkable differences in the concentrations of PC and PE were observed and only PI contents systematically lowered. A significant negative correlation between PI concentration and surface potential (independent of temperature of growth) was obtained. As the differentiation process in callus progressed, the percentage content of PE fraction was increased. [ABSTRACT FROM AUTHOR] |
