An Eco-Biological Study on the Localy Endemic Species Alchemilla orduensis B. Pawl

Abstract

In this study, the local endemic A. orduensis collected from Persembe plateau of Aybasti district of Ordu provinve, which is characterized by meander geographical formations, was studied. The amounts of N, C, H and S elements were determined in the aboveground and underground parts of samples collected from vegetative and generative periods of plants. S element was found in small amounts in plant samples belonging to the flowering period. It is seen that the amount of N is high in the generative period in the underground part and in the vegetative period in the above ground part. The amounts of C and H were found to be high in both the underground and aboveground parts during the vegetative period. The study area has low temperature and high precipitation climate characteristics. The region where the plant is located has clayey-loamy, slightly alkaline, little calcareous and salty soil properties. However, it was determined that the soil was sufficient in terms of organic matter, pH, available potassium, calcium and magnesium amounts. The flower and fruit, which have an important role in the continuation of the species' extinction, have also been examined morphologically and micromorphologically. In the flower of the species, the perianth consists of epicalyx and calyx. The inflorescence is multi-flowered and the flowers are yellow. Cells on the inner surface of the epicalix have wavy walls. Epicalyx inner surface is reticulate-rugose, sepal inner surface is reticulate surface shaped. The fruit is achene type and its surface is reticulate.
