The production of grapevines in regions of high altitude of Santa Catarina state is recent and there are few data on the behavior of different cultivars. The objective of this work was to verify the effect of different levels of shoot topping and evaluate the influence of two rootstocks on the characteristics of the fruit produced. The experiment was conducted in the city of Sao Joaquim, Santa Catarina state (28o17'38" S and 49o55'54" W), in an altitude of 1.250m, at Villa Francioni Vineyards, with Merlot grapevine grafted on Paulsen 1103 and Couderc 3309. The treatments consisted in different levels of shoot topping, keeping the leaf area of 4.5; 2.5; 2.0 and 1.5 m2 kg-1 of grapes in two rootstocks. The variables evaluated were: number of berries per bunch, berry diameter, pH, total soluble solids, anthocyanins, total polyphenols index, length and weight of the bunch. Plants grafted on Paulsen 1103 showed the maximum efficiency maintaining a leaf area of 3.4 m2.kg-1 of grapes, while plants grafted on Couderc 3309 showed the maximum efficiency maintaining a leaf area of 3.0 m2.kg-1 of grapes. The rootstocks did not present difference for the phenolic compounds. In the 2005/06 cycle, plants grafted on Paulsen 1103 produced the largest berries, but with lower content of total soluble solids. In the 2006/07 cycle, plants grafted on Couderc 3309 produced heavier bunches.

The present work aimed to evaluate the agronomic performance of the seedless grape cultivar Sugraone on four rootstocks in the Sao Francisco Valley. The trial was carried out in a commercial vineyard in Sento Se, State of Bahia for four seasons (2002 to 2004). The treatments were four cultivars of rootstock ('Paulsen 1103', 'SO4', 'Harmony' and '420A'), using a randomized block design. The highest yield per plant and vegetative vigor were obtained on the rootstock Paulsen 1103. Also there was a tendency for higher mass of bunches, mass and size of berries on the same rootstock, although there were variations between seasons. The rootstock showed positive influence on the content of soluble solids, but did not affect the total acidity and TSS/TA. Young plants of grapevine cv. Sugraone showed good agronomic performance on Paulsen 1103, but it is important to continue the studies for a larger number of years to recommend their use in the Sao Francisco Valley.

Aims:Atrial of cv. Malbec grafted to six different rootstocks (Harmony, SO4, 1103 P, 140 Ru, 3309 C and Cereza) and own rooted cv. Malbec (ORMa) was carried out with the aim to study the influence of rootstock on the vegetative and reproductive performance of cv. Malbec. Another objective was to study the relationship between below ground (i.e., rootstock) and above ground (i.e., scion) growth under irrigated conditions, typical of Argentine viticulture.Methods and results: Four groups of rootstocks could be distinguished according to their vegetative and reproductive performance. The first group (Cereza and 3309 C, as ORMa) showed intermediate yield and high vegetative expression (VE). The second group (SO4 and 1103 P) was characterized by high yield and intermediate VE. The third group (140 Ru) displayed intermediate yield and low VE. Finally, the fourth group (Harmony) showed low yield and low VE. 140 Ru showed the highest number of roots, while 1103 P, SO4 and Harmony showed the lowest number. Harmony showed a greater skin to berry ratio than 1103 P and a lower berry weight (1.56 g) than the rest of the treatments (1.7 g on average).Conclusion: Rootstocks influenced the biomass partitioning between leaves, grapes and roots: 140 Ru promoted root and reproductive development; Cereza, 3309 C and ORMa promoted vegetative development; SO4 and 1103 P promoted grape yield; and Harmony promoted root development.Significance and impact of the study: The absence of a general behavior pattern highlights the need to accurately assess the performance of each rootstock for each zone and each Vitis variety, in order to choose the most appropriate scion-rootstock combination.

Influence of different rootstocks on the vegetative and reproductive performance of Vitis vinifera L. Malbec under irrigated conditions

In order to better understand and elucidate the influence of rootstock/scion interactions under salinity constraint, three grafting combinations have been used: Superior Seedless/110R, Muscat d’Italie/SO4 and Syrah/1103 Paulsen. Superior Seedless/110R combination behaves and displays the same results as ungrafted Superior Seedless variety under both control and stress conditions. On the other hand, since the sensitive rootstock SO4 could improve the behavior of Muscat d’Italie variety against salinity, it highlights the beneficial effect of this combination even the two genotypes are not really tolerant. This gain of performance at both vigor and salinity tolerance levels would result from hybrid vigor. Likewise, even the rootstock 1103P is moderately sensitive, it reaches to improve the behavior of Syrah which is a very sensitive variety. Comparative analysis of the different combinations showed that rootstocks do not behave the same in cases they are used individually or in combination with scion. Indeed, the more or less sensitive rootstocks SO4 and 1103P (taken individually) behave better at the salinity tolerance level since combined with their respective scions. Moreover, varieties tested individually display a different pattern when used with a rootstock. Generally, they behave better (Muscat d’Italie and Syrah cases) or at least stay unchanged (Superior Seedless case) against salinity when they are grafted. The displayed behaviors among the different combinations reveal the existence of interactions between genotypes of rootstock and scion, and that not only rootstock dictates the global phenotype. These interactions enhance and improve generally the phenotype of the grafting combination. With a sensitive rootstock (whatever scion is, tolerant or sensitive), we always obtain a gain of performance which is more pronunciated with sensitive rootstocks.

Influence of the Rootstock/Scion Combination on the GrapevinesBehavior under Salt Stress

The use of rootstocks is widespread in modern viticulture; non-grafted Vitis vinifera vines are now grown in only a handful of places with very specific conditions. Since the need to graft vine-scions onto American rootstocks, a lot of work has been performed in which different aspects of the relationship between the vine and the rootstock have been studied. Despite this there are still many open questions, which remained unanswered. The present paper reports a study performed on five ‘Albarino’ clones (MBG-1, MBG-2, MBG-7, MBG-9 and MBG-10), in which the influence of rootstock type (110R and SO4) on a number of agronomic variables was examined. The results show that these rootstocks have no influence on many of the variables which were studied (phenology, cluster size and weight, fertility, yield, and berry size and weight), although they do influence variables such as the probable alcohol content, the quantity of free-run juice, must total acidity and weight of pruned wood. Therefore it is possible to conclude, that rootstocks influence agronomic parameters. Additional key words: agronomic traits, interclonal variability, Vitis berlandieri × Vitis riparia, Vitis berlandieri × Vitis rupestris.

L'effet du cepage (Periquita, Trincadeira, Camarate), du porte-greffe (99 R, 110 R, 140 Ru, 1103 P, SO4, 41 B) et de ses interactions sur le rendement et sur la qualite du mout sont etudies dans un essai etabli en split-plot a Quinta da Folgorosa (VQPRD Torres Vedras). Les resultats de trois annees d'etudes (1992/94) montrent qu'il y a une importante interaction entre les porte-greffes et les cepages en ce qui concerne le rendement et l'accumulation des sucres dans la baie. L'analyse en composantes principales a mis en evidence l'influence determinante du cepage relativement au role du porte-greffe. Les cepages en etude se sont reveles statistiquement tres differents les uns des autres, au moins par une des caracteristiques agronomiques analysees.
