The effects of selected pre-treatments on germination of seeds of Oriental hornbeam (Carpinus orientalis)

Abstract

In the present study, the effect of some pre-treatments implemented on seeds of Oriental hornbeam (Cwpinus orienialis), which has wide geographical variation along Turkey on germination percentage values were investigated. For this purpose, 13 different pre-treatments were implemented to seeds obtained from 17 different populations. According to the obtained results (except control seeds), pre-treatments leading to lowest germination percentage value (8.1%) in Oriental hornbeam seeds was PT10: Keeping seeds for 90 min in sulfuric acid, while highest germination percentage (86.58%) has been obtained with pre-treatment PT 13: Implementation of 40% dose of Baikal EM1 + Biohoumous mixture to the seeds, while lowest germination percentage (40.50%) was observed on seeds collected from P7 (Bartm-Kozcagiz) population, highest germination percentage was observed in seeds obtained from P17 (Art vin-1-lopa) population
