(Lamiaceae) on Mount Nif along with their breeding system and reproductive success were examined. S. smyrnaea, distributed over Mount Nif (İzmir Province) at an altitude of 1510 m, is the study material of this research. To detect the stigma receptivity, the Perex test was applied to 25 young and mature flowers. To detect pollen viability, the MTT method was used. To detect the fertilisation type of the taxon S. smyrnaea, 5 different fertilisation methods were tested on the flowers of the plant. Breeding success was assessed through nutlet formation. While the enzyme activity was calculated as approximately with an average of 71 ppm in 25 young flowers to which Perex tests were applied, it was approximately 60% with an average of 300 ppm in the mature flowers. In the mature flowers, the highest pollen viability was , whereas this rate was for the young flowers. In our study, the self-incompatibility rate of S. smyrnaea was calculated as (ISI) = 22/24 = (between and 1) and it was detected as partially self-incompatible. This result was in line with the fact that the taxon is protandrous.

(Lamiaceae) türünün Nif Dağı populasyonundaki üreme ekolojisi, özellikle üreme sistemi ve üreme başarısı araştırılmıştır. Çalışma materyalini Nif Dağında (İzmir) 1510 m yükseklikte yayılış gösteren S. smyrnaea oluşturmaktadır. Stigma olgunluğunu belirlemek için 25’er adet genç ve olgun
