studies of embryogenic (E) and Non-Embryogenic (NE) calluses as the main
tissues for cytological studies and the cells of primary root meristem
derived from seedling or in vitro cloned plant, as reference tissues.
The cellular parameters, such as Mitotic Index (MI), cell-doubling time
(Cdt), cell and nuclear area and DNA C value of the different tissues,
which may be involved with cell activity, have quantitatively been compared.
Embryogenic callus of sugar beet, containing meristematic centers unlike
the non-embryogenic one, the cytological behavior of their cells was very
close to typical meristematic tissue i.e., primary root of seedling. In
non-embryogenic cells, increased in the rate of cytoplasm/nuclear (C/N)
area, endoreduplication and reduction of mitotic index followed by increasing
of cell doubling times were observed.]]>Avers, C.J.,19781stBayliss, M.W.,19851985pp: 157-177pp: 157-177Butterfass, T.,196614758Cavalier-Smith, T.,197834247278Cavalier-Smith, T.,19851985pp: 179-197pp: 179-197Clowes, F.A.L.,196112283293Crevecur, M., D.
