“…Previous descriptive studies of this topic have been done either in grapevine clones differing in their bunch compactness (Alonso-Villaverde et al 2008), in plants of the same cultivar subjected to different cultural or chemical treatments focused to obtain looser bunches (Sarooshi 1977, Vail et al 1998, Poni et al 2008, Valdés-Gómez et al 2008, Vartholomaiou et al 2008, Schildberger et al 2011, Molitor et al 2012a, Palliotti et al 2012, Intrigliolo et al 2014, or in a small number of cultivars Marois 1991, Shavrukov et al 2004).

“…The determination of the main factors having major influence on bunch compactness is essential, because this trait has a large impact on grape quality. Previous descriptive studies of this topic have been done either in grapevine clones differing in their bunch compactness (Alonso-Villaverde et al 2008), in plants of the same cultivar subjected to different cultural or chemical treatments focused to obtain looser bunches (Sarooshi 1977, Vail et al 1998, Poni et al 2008, Valdés-Gómez et al 2008, Vartholomaiou et al 2008, Schildberger et al 2011, Molitor et al 2012a, Palliotti et al 2012, Intrigliolo et al 2014, or in a small number of cultivars Marois 1991, Shavrukov et al 2004). It is clear that different variables may have a significant influence on the variation of bunch compactness in particular cases, but a study aiming to discover the genetic determinants affecting this trait requires a wider framework.…”

“…Consequently, numerous treatments have been tested to reduce bunch compactness in both wine and table cultivars, including the use of gibberellins (Vartholomaiou et al 2008, Evers et al 2010, Hed et al 2011, Molitor et al 2012a), prohexadione-calcium (Lo Giudice et al 2004, Vartholomaiou et al 2008, Schildberger et al 2011-N'-phenyl-Urea (CPPU)] (Zabadal and Bukovac 2006) and other innovative products (Abd-Allah et al 2013, Hanni et al 2013, as well as cultural practices, such as leaf removal (Evers et al 2010, Sabbatini and Howell 2010, Kotseridis et al 2012, Palliotti et al 2012, Tardáguila et al 2012, Intrigliolo et al 2014, bunch thinning (Tardáguila et al 2012) and alternative vine management systems (Zabadal and Dittmer 1998, Archer and van Schalkwyk 2007, Molitor et al 2012b). Many of these strategies also affect the final number of berries in the bunch, producing a reduction of crop yield.…”

“…Many different structural elements of the grapevine bunch have been reported by different authors as key factors defining bunch compactness. Studies of clones or in plants of a single cultivar subjected to different treatments for the loosening of the bunch have identified the number of berries (Poni et al 2008, Vartholomaiou et al 2008, Palliotti et al 2012, their individual size (Alonso-Villaverde et al 2008, Schildberger et al 2011, Palliotti et al 2012, the bunch length (Molitor et al 2012a), the pedicel length (Sarooshi 1977) and the bunch mass (Vail et al 1998, Valdés-Gómez et al 2008 as the key factors in the variation of bunch compactness. The last factor was also highlighted by Vail and Marois (1991) in a work with four grapevine cultivars with different bunch morphology (Barbera, Cabernet Sauvignon, Colombard and Semillon).…”

Background and Aims Grapevine bunch compactness is an important trait with impact on fruit quality, mainly affecting the susceptibility to bunch rot. Many and different variables have been reported to have a significant influence on the variation of bunch compactness in particular cultivars, but little is known about the role of such variables in a wider framework. The aim of this work was to identify and weight the features responsible for the natural variation in bunch compactness in a large and diverse grapevine collection. Methods and Results Different statistical tests were sequentially applied to select the determining variables most influencing bunch compactness. Significant and low correlation was obtained for most of the variables studied for three consecutive seasons, confirming the multifactorial nature of this trait. Multivariate analyses indicated that there are three groups of variables with a significant influence on bunch compactness. Two groups, represented by the total number of berries per bunch and by the length of the first ramification of the bunch, are major factors responsible for the trait variation, whereas berry dimensions have a secondary role. Conclusions Bunch compactness is defined by the difference between its morphological (apparent) volume and its actual (solid) volume. The results showed that the actual volume is mainly determined by the total number of berries, whereas the morphological volume also depends on its spatial arrangement, determined by the architecture of the rachis. Significance of the Study This is the first multiyear study of bunch compactness at a multicultivar level, and it has allowed the selection and weighting of the main variables affecting the trait. These variables are suitable targets to study the underlying genetics of the trait.

“…A common cultural practice consist is to incorporate fertilizers in the soil surface at the end of winter, a period in which the vine needs in nitrogen are negligible (Lie et al, 2015). However, excessive nitrogen concentration in the soil leads to a decreased grape quality and increased sensitivity in grape pests and diseases (Vartholomaiou et al, 2008). This may damage vines and increase the cost of plant protection.…”

In this study the effectiveness of the environmentally friendly fertilizers AXION RED, BIO.L.A and QUATTRO to improve soil fertility and the nutrition status of vines was examined. Application of above three fertilizers increased significantly the level of organic matter, K, P, Mn and Fe in soil. AXION RED also improved the concentration of Ζn, Β, and Cu. Tissue analyses showed that the leaf P content was significantly increased in the vines treated with the fertilizers in comparison to control in 2012. The fertilizer QUATTRO increased the leaf concentrations of Fe and Mn contents in 2012. It was found that the fertilizer BIO.L.A significantly increased the leaf N content, while the fertilizer QUATTRO increased the leaf B content in 2013. Although there was no statistically difference, the leaf P, K and Fe contents were increased in vines treated with each one of the fertilizers tested.The results also showed that all fertilizers increased the fruit N content in comparison to control. The percentage of fruit rot was significantly higher on bunches treated with each one of the fertilizers tested than the untreated control. Finally, the results of this study showed that only the fertilizer QUATTRO significantly increased the bunch weight in 2012.Generally, the above fertilizers improved the nutrition status of vine plants and also improved the soil fertility. However, the increased fruit N content in the grapes treated with each one of the fertilizers increased the susceptibility of fruits to pathogens causing fruit rots and therefore growers should consider its use carefully.

Bunch compactness plays an important role in the sanitary status and perceived quality of table and wine grapes, being influenced by cultural practices and by environmental and genetic factors, which are mostly unknown. In this work, we took advantage of genetic, genomic and bioinformatic advances to analyze part of its molecular basis through a combination of transcriptomic and association analyses. Results from different transcriptomic comparisons between loose and compact grapevine clones were analyzed to select a set of candidate genes likely involved in the observed variation for bunch compactness. Up to 183 genes were sequenced in a grapevine collection, and 7032 single nucleotide polymorphisms (SNPs) were detected in more than 100 varieties with a frequency of the minor allele over 5%. They were used to test their association in three consecutive seasons with bunch compactness and two of its most influencing factors: total berry number and length of the first ramification of the rachis. Only one SNP was associated with berry number in two seasons, suggesting the high sensitiveness of this trait to seasonal environmental changes. On the other hand, we found a set of SNPs associated with both the first ramification length and bunch compactness in various seasons, in several genes which had not previously related to bunch compactness or bunch compactness-related traits. They are proposed as interesting candidates for further functional analyses aimed to verify the results obtained in this work, as a previous step to their inclusion in marker-assisted selection strategies.
