Abstract
This study was carried out to investigate the impact of some training systems on bud behaviour, vegetative growth, yield and fruit quality of Thompson Seedless grapevines. Seven training systems were applied: Head, Cordon Rowaia, Lenz Mozer, Umbrella, Traditional, Double T and Y shape systems.
The results showed that both Y shape and Double T training systems were effective in increasing percentage of bud burst and bud fertility coefficient, average number of clusters/vine, average cluster weight, yield/vine and improving physical and chemical characteristics of clusters and berries. Positive effects were achieved concerning dynamics of wood ripening, morphological characteristics of vegetative growth in comparison with the other training systems. On the other hand, Cordon Rowaia training system was found to record the minimal values of these characters.
