Despite being the world leader in production of hazelnuts, Turkey’s nut yield per hectare is quite behind other producer countries. The main reasons for low are completion economic life hazelnut orchards and lack pruning following technique. Hazelnuts grown with ‘ocak’ system Turkey. ocak a bush-like growing technique that does not contain trunk but consists shoots instead. It necessary to main...

Dormancy of hazel (Corylus avellana L.) seeds is alleviated by a chilling treatment during which cytological, hormonal, and biochemical changes occur. Phytic acid and phosphate mobilization have been examined during this treatment. Phytic acid accounted for 0.7% and up to 3.2% of dry weight in axiferous and cotyledonary tissue, respectively. Phytic acid levels in embryonic axes were reduced by ...

Adventitious root formation in plant cuttings is influenced by many endogenous and environmental factors. Leaf photosynthesis during rooting of leafy cuttings in hard to root species can contribute to supply carbohydrates to the intensive metabolic processes related to adventious root formation. Light intensity during rooting is artificially kept low to decrease potential cutting desiccation, b...

Establishing physiological thresholds to drought-induced mortality in a range of plant species is crucial in understanding how plants respond to severe drought. Here, five common European tree species were selected (Acer campestre L., Acer pseudoplatanus L., Carpinus betulus L., Corylus avellana L. and Fraxinus excelsior L.) to study their hydraulic thresholds to mortality. Photosynthetic param...

The knowledge of pollen sensitivity and tolerance to stress factors such as air pollution is important for forest sustainability, ensuring the most efficient production with highest benefits lowest resource losses. This study intended evaluate influence common pollutants in four trees species, Betula pendula Roth, Corylus avellana L., Acer negundo L. Quercus robur through a comparative analysis...
