Title
Nursery Evaluation Of Different Grafting Techniques For A Sustainable Viticulture Using 99 R And 5 Bb Rootstocks
Abstract
With an increasing interest for environmentally sound viticulture in sustainable agriculture, the selection of concrete cultivar and/or rootstocks as well as convenient grafting technique interactions become more important. Therefore, the aim of the present study was to evaluate different grafting methods in terms of nursery production. Italia cultivar was grafted on one year old 5 BB and 99 R rootstocks by cleft, omega and chip-budding in glass house. Grafting methods were comparatively evaluated on rootstocks separately with respect to certain factors that determine the degree of compatibility between scion and rootstock. Bud break and shoot emergence commenced earlier in chip-budded grapevines than those of other grafts. Shoot length, shoot diameter and the number of leaves per shoot were significantly higher in chip-budding. The highest percentages of graft final take were also obtained from chip-budded grapevines with the values of 80.0% and 66.7% for 99 R and 5 BB, respectively. Overall, chip-budding method would be recommended to apply when the grafting of rooted grapevines was considered.
