| Abstract:
Field trials were carried out over four years to evaluate the performance of Sauvignon blanc, own-rooted and grafted onto six rootstocks, not frequently used, 193 Ruggeri, 300 Ruggeri, 325 Ruggeri, 125-2 Mgt, 1323 Paulsen, Teleki 5A, and Kober 5BB. Vines were planted in a vineyard replant site in the AOC area "Bosco Eliceo" of North-eastern Italy. Shoot growth was higher on plants grafted onto Kober 5BB, and pruned cane weight was higher on 325 Ru and Kober 5BB. Yield of vines grafted onto 325 Ru was superior since the first year, while plants onto 1323 P produced the lowest yield. No differences were found regarding must composition. Examination of the roots revealed that no phylloxera or nematode damages occurred. Some of the rootstock, tested, were able to give higher performance than those of rootstocks traditionally used and are worthy of more interest and further testing. | |
