“…In a recent paper [34], two wine varieties, Merlot and Cabernet Franc, presented 90 and 94%, respectively, of actual fertile buds, higher than our values, but some other varieties such as Prosecco, Fiano, or Sagrantino had 30-40% of fertile buds, even lower than Sugraone in this trial. In a study on table grape varieties (Black Magic, Sugraone, Red Globe, Victoria, Michele Palieri, and Italia) conducted in Sardinia region, Italy [35], the actual fertile bud values were quite similar for Black Magic (86.9 vs. 86.0%), Sugraone (43.4 (22.1 vs. 16.9), and significantly different for Red Globe (5.5 vs. 11.7), Michele Palieri (8.0 vs. 14.3), and Italia (10.1 vs. 25.6).…”

“…Many international wine grape varieties generally show highly fertile buds in different worldwide environments, confirming their adaptability to various pedo-climatic conditions and vineyard managements, i.e., pruning, irrigation, fertilization, etc. [33,34].…”

“…The position of the fertile bud influences the pruning system to be adopted, and for varieties that have low fertility of basal buds, it is necessary to adopt a long or mixed pruning system (cane system). By adapting this type of pruning at the position of the most fertile buds, it is possible to increase productivity, as there will be an increase in the number of inflorescences and consequently an increased number of clusters per vine [6,34].…”

Microscopic bud dissection can be used to assess grapevine bud fruitfulness prior to winter pruning and long before actual bud fruitfulness can be measured in the vineyard the following spring. Bud dissections should be performed by qualified and trained personnel because inflorescence primordia are difficult to distinguish in some varieties. In the Puglia region, Southeastern Italy, in 2018 and 2019, potential fruitfulness using bud dissection and actual fruitfulness observed in the vineyard were compared for seventeen table grape varieties. The percentage of fertile buds, the number of inflorescence primordia (IP) per node, and the incidence of primary bud necrosis (PBN) were detected with bud dissection to be used either for managing winter pruning or for predicting yield during the successive season. The data were successively compared with fertile buds and actual bud fruitfulness observed in the vineyard during spring. The table grape varieties examined had similar values of fertile buds and fruitfulness both with bud dissection and in the vineyard. The application of longitudinal sections in bud dissections can be an alternative approach (or can be integrated into traditional cross sections) to distinguish IP in some difficult varieties, but the two techniques can be used together for more repeatable results. The bud dissection technique (with both cross and longitudinal sections) can provide useful insights for viticulturist to help guide winter pruning (intensity of pruning and number of canes) and to predict potential yield.

“…Evaluating the productive parameters of the first crop (2018/19), no difference in the fertility index caused by the rootstocks and the spacing was found. Fertility is a genetic characteristic of grapevine varieties, and reflects the ability to differentiate vegetative buds from fruiting buds, which will determine their productivity (Meneguzzi et al, 2020).…”

Rootstock adequacy and planting density are necessary for new grapevine varieties in new regions. The objective of this work was to select the rootstock that confers the best productive performance to the ‘Vermentino’ variety, and to adjust the ideal spacing for this combination. The experimental design used was randomized blocks in a 5x3 factorial scheme, in which the treatments studied consisted of the combination of five rootstocks (‘101-14 Mgt’, ‘Harmony’, ‘IAC 572’, ‘Paulsen 1103’, and ‘VR 043-43’) and three spacings between plants (1.0, 1.2 and 1.5 m). The phenological cycle of the plants and the productive and quality characteristics of the grapes were evaluated during 2018/19, 2019/20, and 2020/21 harvests. Bud break of ‘Paulsen 1103’ and ‘VR 043-43’ rootstocks occurred the latest in 2019/20 and 2020/21. ‘101-14 Mgt’ and ‘Paulsen 1103’ rootstocks induced the highest yields in 2019/20 and 2020/21. The 1.0 m spacing between plants provided the highest productivity in all seasons. Thus, it can be concluded that the ‘Paulsen 1103’ and ‘VR 043-43’ rootstocks delayed bud break and decreased phenological sub-periods. ‘Paulsen 1103’ and ‘101-14 Mgt’ rootstocks contributed to increase the productivity; the ‘IAC 572’ rootstock presented the lowest contribution to the polyphenols content and antioxidant activity, and the 1.0 m spacing between plants resulted in greater productivity of the vineyard.

“…However, it is not a constant value, as it depends on numerous factors, namely: variety, bud type (primary or secondary) and bud position in the cane, climate and vine physiology influence on the differentiation of the inflorescence primordia (Magalhães, 2015). An evaluation of bud fruitfulness can thus provide useful information for determining yield potential for the next growing season (May and Antcliff, 1973;Dry, 2000;Meneguzzi et al, 2020;Monteiro et al, 2021). The number of inflorescences, and therefore clusters per vine, can be responsible for about 60 % of seasonal yield variation, while the number of berries for approximately 30 % (Clingeleffer et al, 2001;Guilpart et al, 2014).…”

Assessment of bud fruitfulness of three grapevine varieties grown in northwest Portugal

Assessing bud fruitfulness (fertility) before budburst can provide useful information for determining the yield potential for the following growing season and allows the number of buds per vine to be adjusted according to the productive potential of each season. The present study aims to assess bud fruitfulness and the incidence of necrotic buds using different analysis techniques in three spur pruned (cordon) grapevine white varieties planted in the Vinhos Verdes Demarcated Region (VVDR), NW Portugal. The first two dormant buds and cane samples were collected before winter pruning in December 2016 and 2017 from three (Vitis vinifera L.) varieties (Alvarinho, Fernão-Pires and Loureiro) in two different VVDR sub-regions. The fruitfulness and the incidence of bud necrosis were determined using anatomical bud analysis and by forcing bud growth under controlled environmental conditions. Additional analyses were performed to determine the total soluble sugars and starch in cane samples on node and internode regions. There were significant differences in fruitfulness among varieties over the two growing seasons (2016/2017 and 2017/2018). The Fernão-Pires variety showed the highest bud fruitfulness for the two first buds of the three varieties. Total soluble sugars and starch content were influenced by the site, variety and position on the cane. A year-to-year variation was observed, with a decrease in bud necrosis and an increase in the fruitfulness indices and carbohydrates content from 2016/2017 to 2017/2018. To our knowledge, no previous studies combining anatomical and forced bud growth techniques have been carried out on these three white varieties.
