The temperature requirement is important factor for
adaptation to an ecology of any plant species.Plant seeds
growing in the places with high altitutes are excepted to
well develop at lower temperatures. In addition, temperature
highly determines when seeds will germinate under field
conditions.With different flower colors and appearence,
Centaurea is an annual,biennial and perennial plant
genus,alternatively used for culture plants in landscape
architecture works. Centaurea virgata growing at
1750 altitude were germinated at different
temperatures.Their germination rate and their percentage of
germination were investigated and the best germination
temperature assessed. In this study,seeds from roadsides and
fields of Centaurea balsamita,
Centaurea iberica
and C. virgata growing at 1750 altitute were
germinated at different temperatures.Their germination speed
and germination percentage were investigated and the best
germination temperature was assessed.As a result, the best
germination percentage and speed was C. balsamita at 15°C.
Key words:
Seed, germination, Centaurea. |
