Each of the grape cultivars [Vitis species, (L) Batch], `Concord', `Himrod', `Challenger', `Reliance', `Glenora', `Moored', planted June 1983, and `Mars' planted Spring, 1987, was trained to the 4-cane Kniffin (KN) and the Geneva Double Curtain (GDC) systems. Yield per vine, pruning weight, number of nodes, cluster weight, number of berries per cluster, berry weight, and percent soluble solids were recorded. Vines from `Reliance' trained to the KN system produced fruit with significantly higher percent soluble solids than did vines trained to the GDC. No significant differences in percent soluble solids were observed between the two training systems for the other cultivars. `Concord' produced more kg/vine of pruning weight when trained to the KN system than when trained to the GDC. Pruning weight did not differ significantly between the two training systems for the other cultivars. Cultivars more productive (yield/vine) on the GDC trellis were `Concord', `Himrod', `Reliance' and `Moored' whereas `Challenger' was more productive when vines were trained to the KN system. No differences between the two training systems were observed for `Glenora' or `Mars'.

<p style="text-align: justify;">A study was conducted to determine the effects of post-bloom applications of forchlorfenuron (CPPU) at 5 and 10 ppm, and the practice of cane girdling on fruit quality of two table grape cultivars (cvs.) « Perlette » (seedless) and « Italia » (seeded). For « Perlette » cv, CPPU treatments increased significantly berry weight and crop per vine, relatively to the control. However, soluble solids decreased while the acidity increased, reflecting a late maturation of berries from the treated vines. The delay of fruit maturity was also observed in « Italia » grapes, measured by a significant decrease in fruit soluble solids content. Girdling had a slight and non significant effect on fruit quality for both cvs.</p>

Abstract The increase of rural tourism activities has led growers to use different grape cultivars for the production of wine and/or juice. Thus, the aim of this study was to evaluate the phytotechnical characteristics of grapevines and physicochemical characteristics of grape must obtained for Bordô, Isabel Precoce, BRS Violeta, Isabel and Concord cultivars in different training systems: vertical shoot position; Y-shaped trellis and V-shaped trellis with double spur cordon. The experimental design was randomized blocks for comparison of cultivars within each training system and analysis of the main components for productivity variables was carried out. BRS Violeta cultivar showed higher bunch weight values regardless of training system. Bordô cultivar showed lower yield values and soluble solids content in comparison to other cultivars. Isabel and Isabel Precoce cultivars in the evaluated training systems showed higher soluble solids content. Principal component analysis allowed verifying that in Y-shaped trellis and V-shaped trellis with double spur cordon training systems, cultivars were related to higher yield.

`Jupiter' is the fifth table grape cultivar released from the Univ. of Arkansas grape breeding program. `Jupiter' originated from a cross of Ark. 1258 × Ark. 1672 made in 1981. The original seedling vine was selected in 1984, and `Jupiter' was tested as Ark. 1985. `Jupiter' was tested at two locations in Arkansas (Fayetteville and Clarksville) and at West Lafayette, Ind. Fruit of `Jupiter' are reddish-blue, and berry weight averaged 5.5 g over 12 years of evaluation at Clarksville. Fruit are seedless, have a non-slipskin texture, ripen early mid-season, and averaged 19.8% soluble solids. Flavor is a mild muscat, a noteworthy character of this new cultivar. Clusters averaged 257 g over 12 years and are well-filled. Yields of `Jupiter' have been very good, exceeding 29 t/ha at Clarksville. Hardiness of `Jupiter' was greater than `Einset Seedless', `Himrod', or `Vanessa Seedless', but less than `Mars' or `Reliance' at West Lafayette. `Jupiter' is recommended for trial where other other eastern U.S. table grape cultivars are adapted.

Four interspecific grape hybrids (Vitis spp.) developed in Arkansas were evaluated for primary bud hardiness by differential thermal analysis. Buds from two locations were analyzed over 2 years for acclimation, midwinter hardiness, and deacclimation. In addition, effects of two training systems on cold hardiness of buds were evaluated in one location. The buds of the two genotypes with the greatest component of V. vinifera in their ancestry acclimated more slowly than did the other genotypes. Ultimate midwinter bud hardiness was greater in the genotypes possessing less V. vinifera than other parentage. No effect on cold hardiness due to training system was noted. No natural winter freeze damage was observed on any of the genotypes in the period of observation.

Production system and environmental factors might cause changes in grapevine physiology, affecting grape yield, quality, phenolic composition, and antioxidant potential. The aim of this study was to characterize the quality and antioxidant potential of 'Isabel Precoce' grapes on different training systems and rootstocks in warmer seasons, in tropical conditions. Experimental design was in randomized blocks, in sub-subplots through time and four replicates. Three training systems (overhead trellis, lyre and vertical shoot positioning - VSP) and two rootstocks (‘IAC 572’ and ‘IAC 766’) were studied in the production cycles from July to October, 2017 and from July to October, 2018 in the Submedium of São Francisco Valley. Berry weight; cluster weight; color attributes; berry resistance to compression (COMP); titratable acidity; soluble solids; total soluble sugars (TSS); yellow flavonoids; total anthocyanins; total extractable polyphenols and antioxidant activity by ABTS●+ and DPPH● free radical capture methods were analyzed. Lyre and VSP resulted on increases of 6% and 17% in berry weight and COMP, respectively. Moreover, differences between production cycles were more intense for both variables. In production cycle from July to October 2017, lyre and VSP systems provided increases of 2 g 100 g-1 of TSS and higher anthocyanin and yellow flavonoid contents, while grapes trained in VSP had higher antioxidant activity. Mean values of anthocyanins reached 529.34 mg 100 g-1 in grapes harvested in October 2017. Some grape quality and chemical components showed high variation in warmer seasons of sucessive years, according to training system or rootstock and their combinations

Overall Performance

‘Diamond Muscat’, ‘DOVine’, ‘Fiesta’, and ‘Selma Pete’ grapevines (Vitis vinifera) were evaluated to determine their suitability for making dry-on-vine (DOV) raisins on an open-gable trellis. The experiment was a split-plot, with training system, head, bilateral, or quadrilateral cordons as the main plot, and grapevine cultivar (Diamond Muscat, DOVine, Fiesta, or Selma Pete) as the subplot. Yield components, fruit composition, and raisin yield and quality were evaluated annually. Vine training style did not affect fruit composition, or raisin yield or quality, but vines trained to quadrilateral cordons produced more clusters on renewal shoots than head-trained vines. ‘DOVine’, ‘Fiesta’, and ‘Selma Pete’ produced about 4.75 tons/acre of raisins, ≈10% more than ‘Diamond Muscat’. ‘Diamond Muscat’ vines produced the most clusters on renewal shoots, an undesirable trait, and the most clusters per vine. ‘Fiesta’ matured later than the other cultivars, therefore it had the lowest soluble solids, the poorest raisin grades, and the highest field moisture at harvest. ‘Selma Pete’ grapes matured as early, or earlier, than the grapes of other cultivars, they had among the highest soluble solids and raisin grades, and the raisins generally dried well. Thus, ‘Selma Pete’ grapevines had the best overall performance of the cultivars tested.

Combined Data

The influence of bilateral cordon (BC) and cane training systems and level of pruning severity on vegetative and reproductive characteristics of Vitis hybrid `Suwannee' were determined from 1987 to 1989. In 1987, yield and quality were similar on BC- and cane-trained vines. In 1988, shoot count, yield, and quality were similar regardless of training system and pruning severity (50, 70, or 90 nodes per vine). When data from both training systems were combined, yield was related to the number of shoots. Vines pruned more severely compensated by producing more shoots from non-count (non-node) positions on the canes, cordon, or spurs. Similarly, in 1989 yield and berry quality were not affected by training system or levels of pruning severity (50, 70, 90, or 110 nodes), although berry weight was affected by training system, and shoot count and shoot length were affected by level of pruning severity. Interactive effects of training system and pruning level were not significant in either year. An analysis of combined data for 1989 indicated that yield was affected by the number of nodes and shoots. Thus, `Suwannee' may be trained to the BC system, which is more readily adapted to mechanization. Pruning to a specific number of nodes per vine was not critical.

Own-rooted 'Seyval Blanc' vines were evaluated over 5 years in the following training systems: bilateral cordon, bilateral cordon sylvos (sylvos), upright cordon-spur pruned, and upright cordon-cane pruned. Vines in all systems were spaced 1.8 x 2.7 m and were shoot thinned to 40 shoots and cluster thinned to one cluster per shoot. Cumulative yields over 5 years of the upright cordon systems were higher than vines in the sylvos system. Average weight of cane prunings was higher in the upright cordon vines than in all other systems. Vines trained to the sylvos system had more canopy gaps, less Botrytis bunch rot, and higher juice soluble solids than other systems in some years. The chemical constituents of the must and wine or evaluation by tasting showed little influence of training system.

The choice of training system may influence vineyard efficiency in terms of light interception and water consumption, particularly in the current context of climate change. On this basis, during the 2017 season, Sangiovese potted vines were grown outdoors using two different training systems: guyot vertical shoot positioned system (C) and V-shaped open canopy (A). From the end of June until September, vine transpiration was continuously monitored by the gravimetric approach and at different times in the season, the leaf area, light interception, photosynthetic activity and stem water potential were measured. Grape yield and fruit composition were recorded at harvest. C plants did not differ from A in terms of leaf area during the entire season. Light interception was higher in C vines during the early hours of the morning and lower in the central part of the day and the transpiration loss was higher, as was the net photosynthesis detected on some days in August. No differences were detected in terms of yield but a significant increase in soluble solids was found in C compared to A. The open canopy compared to a closed one, in a particularly hot year like 2017, resulted in negative consequences on the accumulation of soluble solids, probably as a result of the radiative stress suffered by the A vines in the middle hours of the day.

Deciduous Fruit

Apple is one of the most consumed fruits in the world. In Brazil, apple is the deciduous fruit of major importance. Its production is focused in the southern region of the country. To increase apple tree yield and to optimize fruit quality, it is important to choose a suitable training system to obtain greater light interception and photosynthetic radiation. Therefore, the objective of this study was to evaluate vegetative and productive aspects of the cultivar Maxi Gala grafted on seven-year-old dwarf rootstock M.9, under three different training systems: Tall Spindle, Solaxe and Vertical Axis. The experimental orchard was implemented in August, 2010 in Vacaria city, Rio Grande do Sul province, Brazil. The experiment was conducted and evaluated in (2014-2017) seasons. The results showed that Tall Spindle, Solaxe and Vertical Axis driving systems had no effect on internode length, plant height, fruit diameter and quality parameters such as pulp firmness and soluble solids. Therefore, the Tall Spindle driving system was more efficient for accumulative production, being this the indicated combination for regions with the edaphoclimatic characteristics like those of the orchard under study.
