VERIFICA DELL’ATTECCHIMENTO DEGLI INNESTI-TALEA DI VITE DOPO LA FORZATURA MEDIANTE TECNICHE TERMOGRAFICHE E MECCANICHE

Grafting is an important technique for getting good yields in plant multiplication. Understanding the success of the graft after the incubation room is important to the evaluation of the suitable grafting for the open field (nursery). Successful grafting in vines requires the development of a functional vascular system between the scion and the rootstock. The graft compatibility and its augmentation depend upon various natural factors like environment, weather, soil conditions and protective measures etc. The present study examines the capability of thermography, mechanical and electrical techniques to assess the graft quality and successful of Vitis vinifera after the incubation room. After the different tests, we were able to distinguish the successful grafting only with the thermographic test. Moreover, this technique was the only non-destructive test from which it was possible to derive quantitative parameters, useful to do the nursery successful forecast. Engraftment results detected at the nursery showed a 15% error in forecast based on the proposed thermal image method, satisfactory value for a feasibility study.
