- Roots: When the plants are grown on MS (
Murashige & Skoog
medium) the roots are found not to be straight, but somewhat thickened
and
tortuous ("krumpelig"). The number of root hairs is greater than normal.
Therefore the roots form rather a lump than a normal branched and
extended system. (Personal communication from I. Heidmann, 22. May 1997)
