“…In most winegrowing regions of the world, vineyards are established using grafted grapevines. This is mainly to avoid root damage from phylloxera (caused by the insect Daktulosphaira vitifoliae) and certain nematodes, which affect grape yield and quality and can be devastating (Miele and Rizzon, 2017). Rootstocks are also used to help vines cope with adverse soil conditions (salinity, alkalinity, acidity) and extremes in water availability (drought and flooding).…”

Aim: In this study, we aimed to evaluate the composition of grapes and wines of the Alicante Bouschet variety from a tropical semi-arid area in Brazil, by studying two rootstocks and harvests in different semesters (climates) of the same year.Methods, Results: Vines of Vitis vinifera L., Alicante Bouschet, a teinturier variety, were grown in a tropical semi-arid climate in Brazil. The phenolic composition of the grapes and wines was measured to assess how they had been affected by two rootstocks (IAC 572 and 1103P) and two harvest seasons, Semester 1 and Semester 2 (in this region, a grapevine produces two harvests per year, with an intra-annual climate variability). The grapes and wines were subjected to the usual physicochemical analyses, as well as to spectrophotometric and chromatographic analyses. Sensory analysis was carried out by professional tasters. The results show that there is a rootstock effect and a harvest season effect for several parameters on grape composition, as well as on the resulting wines. The grapes from vines grafted onto IAC 572 rootstock contained higher titratable acidity, tartaric acid, malic acid, total anthocyanins, total proanthocyanidins in skins and seeds and polymeric tannins in skins. The grapes from vines grafted onto 1103P rootstock contained higher concentrations of total phenols and non-flavonoids, total monomeric anthocyanins, monomeric and polymeric tannins in the seeds. The second semester wines were higher in total anthocyanins, total phenols, flavonoids and non-flavonoids, condensed tannins and low molecular weight flavanols, astringency potential, colour intensity, titratable acidity, total dry extract and alcohol content.Conclusions: The results demonstrate an influence of rootstock and harvest season (semester/climate) on grape and wine composition. Some of the grape and wine phenolic compounds analysed individually (some monomeric anthocyanins and low molecular weight flavanols) were higher in the first semester than in the second. The overall phenolic parameters determined in grapes and wines from the second semester were higher than those from the first. According to the sensory analyses, the semester (climate) effect was stronger than the rootstock effect, and the wines from the second semester received the highest scoring than those from the first semester, mainly for olfactory and gustatory attributes.Significance and impact of the study: This study uses a holistic methodology, mainly with respect to the phenolic compounds, to examine the combined effects of rootstocks and intra-annual climate variability on grape and wine composition. The results of this study may contribute to future research, as well as help the producers and wine companies of tropical regions to tailor viticultural and oenological parameters, in order to improve the quality and typicality of the products.

“…Significant results indicating lower pruning weight and/or yield for '101-14 MG' in comparison with '3309 C' were observed in trials with the 'Syrah' (Agut et al, 2005), the 'Fernão Pires' (Andrade et al, 2005), the 'Cornalin' (Spring et al, 2012) and the 'Albarín Tinto' cultivars (Loureiro et al, 2016). Contradictory results with a significantly higher berry yield of 'Pinot Noir' and 'Cabernet Sauvignon' on '101-14 MG' compared to '3309 C' were noticed by Koblet et al (1994) and Miele and Rizzon (2017), respectively. Brighenti et al (2012) and Yuste et al (2017) did not find differences between the two rootstocks in terms of grape yield and pruning weight with 'Cabernet Sauvignon' and 'Sauvignon Blanc' cultivars, respectively.…”

Grapevine (Vitis vinifera L.) cultivation in Asturias (Northwestern Spain) was on the brink of extinction in the last century. Nevertheless, the present century is witnessing its rebound as a consequence of the recognition of the Cangas Wine Designation of Origin. The long period of abandonment has resulted in a lack of information about the most suitable rootstocks for the attainment of optimal quality. In this study, the agronomical and oenological parameters of the ‘Verdejo Negro’ cultivar grafted on three rootstocks (‘196-17 C’, ‘101-14 MG’ and ‘3309 C’) were studied. Three repetitions of ten vines for each rootstock were disposed in a completely randomized design. Agronomical (phenology, yield, pruning weight and Ravaz index) and enological (berry, must and wine composition) parameters were measured, and the elaborated wines were sensorially evaluated. Concerning phenology, the ‘101-14 MG’ rootstock advanced the veraison in the last two years of the study. The year significantly influenced many of the agronomical and enological parameters, whereas the rootstock only affected the Weaver index, which was higher for the ‘101-14 MG’ rootstock, indicating a more advanced maturation with this rootstock, and at the wine volatile acidity, higher for ‘3309 C’ wines. When the wines of ‘Verdejo Negro’ grafted on the three studied rootstocks were sensorially evaluated, few differences were found. Wines from ‘101-14 MG’ scored slightly better for nose parameters, although the overall judgment was very similar for all the wines. Considering the small effect of the rootstocks on the wines of ‘Verdejo Negro’, there is no clear recommendation at present. But it is important to take into account the effects of climate change, since the advance of maturation induced by the ‘101-14 MG’ rootstock may hinder the production of balanced wines of the ‘Verdejo Negro’ cultivar in the future. The predicted earlier ripening may lead to grapes with excessive sugar level, low acidity and a decoupling of phenolic and technological maturity.

“…The size of the pseudostem girth also indicates, the amounts of soil nutrients and water required to support banana growth [12]. It also indicates plant growth vigor [13]. Hence, the FHIA banana clones have higher plant vigor and potential for higher volumes of soil water and nutrients uptakes compared to the indigenous banana clones.…”

On station experimental trial on the growth performance and resistance against black sigatoka of the indigenous and exotic banana clones were evaluated at Mbarara Zonal Agricultural Research and Development Institute. The experiment composed of 11 indigenous and 3 exotic banana clones planted at 3 × 3 m, and replicated three times in three blocks, was laid in a Complete Randomized Block Design. Data on banana growth parameters and susceptibility to black sigatoka were collected in the 3 rd and 4 th crop cycles. Both the indigenous and exotic banana clones exhibited high growth and yield potentials in the semi-arid conditions of the southwestern agroecological zone of Uganda. Kabucuragye and Williams had significantly (p < 0.05) taller and shorter pseudostems compared to other banana clones, respectively. FHIA 17 and FHIA 23, exhibited the largest pseudostem girths of 84.97 cm and 75.4 cm, respectively. Also, the highest number of leaves was observed with the same banana clones: FHIA 17 (12.8) and FHIA 23 (12.6), indicating that they had the highest growth vigor. Mporogoma exhibited significantly (p < 0.05) more fingers on hands, in turn leading to significantly higher bunch weights compared to other indigenous banana clones. Nonetheless, FHIA 17 and FHIA 23, had significant superior bunch weights. Exotic and Mporogoma indigenous clones were most susceptible to black sigatoka among all the banana clones.
