Abstract:
The
chromosome number, karyotype and pollen analysis of Turkish endemic
species Tordylium elegans (Boiss. & Bal.) Alava & Hub.-Mor. are
reported in this paper for the first time. The somatic chromosome number
is determined as 2n = 4x = 16. It is a tetraploid species and the basic
chromosome number is x = 4. Haploid karyotype formula is 4sm + 3m + 1T.
The pollen
morphology of T. elegans was examined under light and scanning
electron microscope.
Pollen of
T. elegans
are
radially
symmetrical, isopolar, tricolporate, perprolate and
equatorially-constricted.
