Objective: Main purpose of this study is to determine whether the rates of frost damages on pistils caused by the lower temperature varies between different planting distances and the different training systems with the heights of the peach trees. Material and Methods: The flowers of Monroe/GF 677 peach trees grown in different training systems and planting distances, in the pink bud period, on the 1nd day after the frost that occurred in the period, morning of April 1, hours 5:00 AM-7:00 AM, temperatures -0.33 to -1.23° C, 3 replicates with 100 flowers in each replicate were collected from 4 sides of Slender Spindle, Y-Trellis, Central Leader and Open Vase trees planted with different planting distances from both 1m and 2m height. Results: The frost damage rates have been obtained as 5.05% for Slender Spindle training system and 2.05% for Y-Trellis training system in the support systems. In unsupported systems, peach cultivation with the Central Leader training system caused less frost damage. Conclusion: Y-Trellis cultivation system in supported systems and Central Leader in unsupported systems for peach cultivation resulted less frost damage and therefore it was suggested that they were a better systems in terms of productivity. |
