Objective: In
this study the somatic chromosome numbers and detailed morphometric
properties of Tulipa pulchella
(Fenzl ex Regel) Baker was examined.
Material and
Methods: The seeds were germinated on moist filter
paper in petri dishes at 25°C. Actively growing root tips were pretreated
with 0.05 M colchicine for 6 h at room temperature. Then, the root tips were
fixed with acetic alcohol (1:3 glacial acetic acid–absolute ethanol) for at
least 24 h at 4°C, hydrolyzed in 1 N HCl at 60°C for 1-2 min, then rinsed in
tap water for 3–5 min. Finally, they were stained in Feulgen for 1 h and
mounted in 45% acetic acid. Digital microphotographs from at least five
well-spread metaphase plates were taken using an Olympus BX51 microscope X40
objective and were recorded with an Olympus Camedia C-4000 digital camera.
Results: The chromosome number of Tulipa pulchella is determined as 2n =
24 for this taxon. The karyotype consists of 8 submedian region (sm) and 4
subterminal (st) chromosomes. The metaphase chromosome length ranges from
9.35 to 16.48 μm, longest to shortest chromosome ratio was 1.9:4.1, total
karyotype length (TKL) was 150.99 um and the karyotype symmetry was type 1A.
Conclusion: The basic chromosome number of Tulipa
pulchella is x=12. The majority of tulip species and cultivars is diploid
(2n=2x=24), however, encounters to triploids (2n=3x=36), tetraploids
(2n=4x=48) and even some pentaploids (2n=5x=60) and hexaploid (2n=6x=72).
Identifying the chromosome number of this species in this study would provide
a base for biosystematic studies.
