Effects of trellising and baran systems on frost tolerance in Üzümlü (Erzincan) vineyards

Abstract

In this study, the effects of Trellising and Baran systems on the frost tolerance of the dormant buds of the ‘Karaerik’ were determined. In the research, after the winter cold, the one-year old cuttings of the ‘Karaerik’ were taken before the pruning in the spring. The viability rate of primary, secondary and tertiary buds of the first 4 effective bud was determined under a binocular microscope by the sectioning method. As a result, the viability rates of primary buds in the Baran system in 2012, 2013 and 2014 were determined as 20.7, 30.6 and 36.1%, respectively, and the viability rates of the primary buds of the tubules taken from the Trellising systems were determined as 27.8, 38 and 46.1% respectively. Equivalent results were observed for secondary and tertiary buds as well. In the viability test, there was no statistically difference related with the bud level in terms of damage caused by the low winter temperatures between the two systems used. At the end of our study, it has been concluded that it is possible to use the Trellising system as an alternative to the Baran system, which is frequently preferred in the region, with many advantageous aspects.
