Özet

The reproductive ecology of Salvia smyrnaea Boiss. (Lamiaceae) on Mount Nif along with their breeding system and reproductive success were examined. S. smyrnaea, distributed over Mount Nif (Izmir 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 14.2% 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 10.29%, whereas this rate was 70.27% for the young flowers. In our study, the self-incompatibility rate of S. smyrnaea was calculated as (ISI) = 22/24 = 0.91 (between 0.2 and 1) and it was detected as partially self-incompatible. This result was in line with the fact that the taxon is protandrous.
