Comparison of Green Grafting Techniques for Success and Vegetative Development of Grafted Grape Cultivars (Vitis Spp.)
Grafting incorporates a new grapevine cultivar onto the root system of a desired rootstock variety. Recently, many grafting methods have been used in grapevine propagation. A glasshouse trial was conducted to assess three different methods of green grafting (cleft, modified cleft & whip) using Alphonse Lavallée and Perlette cultivars and 99 R rootstock. The highest callusing rates were observed in whip graft type in both Alphonse Lavallée (3.95) and Perlette (3.92). However, modified cleft grafting generally gave better results for most of the growth parameters in both cultivars. For instance, the values relevant to shoot length (62.6 cm & 48.6 cm for Alphonse Lavallée & Perlette, respectively), shoot lignification length (24.7 cm & 16.5 cm for Alphonse Lavallée & Perlette, respectively) and leaf number per shoot (19.9 & 23.0 for Alphonse Lavallée & Perlette, respectively) were higher for both cultivars when modified cleft method was applied.
