SEED GERMINATION BEHAVIOUR OF THREE ALPINE SPECIES FROM ULUDAĞ MOUNT,TURKEY

In this study, the germination requirements of three species from alpine belt of Uludag Mount; Gypsophila olympica Boiss., Matthiola montana Boiss. and Silene rhynchocarpa Boiss. We tested the germination under (20 °C) dark, (20 °C) continuous light, and photoperiod 20/10 °C (12/12h) with distilled water. Different germination behaviour was found for these three species from closely related habitat conditions. G. olympica showed similar germination percentages in dark, light and photoperiod, and germinated faster in light (3.9 days). S. rhyncocarpa germinated 100 % at all the three conditions but faster in dark with 2.0 days. M. montana seeds were found to require light for germination. The germination was 27.2 % at dark, whereas the seeds were germinated 90 % under photoperiod. The results can be useful for both in situ and ex situ conservation of these plant species.
