Effects of restricted irrigation on root morphological properties of wine grapes (Vitis vinifera L.)
Abstract
Aims: This study sought to determine the effects of the application of water restrictions on the morphological characteristics of the roots of wine grape varieties grown in the Thrace region.
Methods and Results: The experiment was conducted in 14 L pots and perlite growth medium using a computerised irrigation and nutrition system. Different water restrictions were applied to ‘Adakarası’, ‘Papazkarası’, ‘Vasilaki’, ‘Yapıncak’ and ‘Cabernet Sauvignon’ cultivars, including 4 different daily total water amounts and no irrigation. At the end of 2 growing seasons, plants were removed and the parameters of number, length, diameter, weight of fine and coarse roots and trunk diameter were determined.
Conclusions: Although none of the studied parameters is sufficient to define exactly the drought tolerance of the cultivars, it shows that they are important for defining the genotypic response of the cultivars to water stress. The cultivar ‘Adakarası’ responds to decreasing water content similarly to ‘Cabernet Sauvignon’. The high number of roots in the ‘Papazkarası’ cultivar can be considered an advantage in terms of adaptation to drought conditions. On the other hand, the ‘Yapıncak’ and ‘Vasilaki’’ cultivars respond to low water with reduced vegetative growth.
Significance and Impact of the Study: In this study, root morphological characteristics of traditionally grown wine cultivars in the Thrace region were investigated for the first time. Knowledge of these traits is important for the adaptability and to take advantage of genetic diversity of local cultivars for the sustainability of viticulture under current climate change conditions.
