“…Modulation of the source/sink balance of grapevines by BT is a valid management practice to regulate berry composition and secondary metabolites (Kliewer and Dokoozlian 2005). Previous studies have demonstrated that BT can hasten ripening, increase TSS and improve berry composition in several grape cultivars, including Pinot Noir (Reynolds et al 1994), Cabernet Sauvignon (Nuzzo and Matthews 2006), Merlot (Bowen et al 2011), Tempranillo (Gamero et al 2014) and Summer Black (Xi et al 2016). A LA/fruit ratio above 0.8 m 2 /kg has been shown to be critical for full ripening of grapes (Kliewer and Dokoozlian 2005).…”

Background and Aims Bunch thinning (BT) is a cultivation approach that strongly influences sugar and anthocyanin accumulation in grapes. Until now, little has been reported describing its underlying mechanisms. The aim was to explore the impact of BT on berry composition, enzyme activity, anthocyanin biosynthesis and gene expression from veraison to harvest in Shenhua grape berries. Methods and Results Vines cultivated in a greenhouse were selected and randomly divided into a Control group and a BT group in which half of the total bunches of each vine were removed 1 week before veraison. Bunch thinning positively influenced the sugar concentration, which could be attributed to the enhanced activity of acid invertase and sucrose synthase (cleavage direction). Bunch thinning also increased the anthocyanin concentration of berry skins significantly, which might be related to the positive upregulation of the expression of most genes involved in anthocyanin biosynthesis. Moreover, the downregulation of F3′H and upregulation of F3′5′H may be responsible for the observed shift of the anthocyanin composition under BT. Conclusion Bunch thinning increased both the sugar accumulation and anthocyanin biosynthesis and positively upregulated the activities of two enzymes, as well as the expression of most of the genes related to anthocyanin biosynthesis. Significance of the Study These findings provide insight into the effect of BT on the sugar accumulation and anthocyanin biosynthesis of grape berries.

“…Irrigation is therefore essential in those regions in order to achieve yields that make grape growing profitable and, as a consequence, a vast corpus of research has lately evaluated how it affects yield, grape, and wine quality for different varieties in semi-arid areas either focusing on comparing different amounts of irrigation water and/or water availability levels across the season (Kliewer et al, 1983;Stevens et al, 1995), or on analyzing the effects of water deficit at certain stages of berry development (Poni et al, 1993;Ginestar et al, 1998;Ojeda et al, 2002;Petrie et al, 2004;Salon et al, 2005;Bowen et al, 2011;Intrigliolo and Castel, 2010;Santesteban et al, 2011;Junquera et al, 2012). However, quite surprisingly, other irrigationrelated factors such as irrigation frequency, emitter spacing and flow rate have been scarcely studied, despite a relevant effect has been observed for annual (Goldberg and Shmueli, 1970;Freeman et al, 1976;Segal et al, 2000;Sharmasarkar et al, 2001;Ertek et al, 2004;Sensoy et al, 2007;El-Hendawy et al, 2008) and for other perennial crops such as apple (Levin et al, 1979), olive (Palomo et al, 2002) and almond (Andreu et al, 1997).…”

“…In recent years, the effects of bud load applications, alone or together with irrigation, on yield and quality in viticulture have gained some more importance (Terry and Kurtural, 2011). In addition, the number of studies looking for an appropriate irrigation strategy and sufficient bud load level for viticulture for different ecological conditions, grape varieties, and cultivation techniques have been increasing (Fawzi et al, 2010;Bowen et al, 2011).…”

“…Along with irrigation, one of the important primary parameters that directly affect yield and quality in grapes is crop load, which represents the number of buds present during the pruning of grapevines (Winkler et al, 1974;Keller et al, 2008;Bowen et al, 2011;Terry and Kurtural, 2011;Geller and Kurtural, 2013). Generally, leaving more buds than required for increasing the yield can result in an insufficient photosynthetic area for satisfying the need of increased fruit load of a plant.…”

The effects of two irrigation practices (RDI-I and RDI-II) and two bud load treatments on the yield and quality of the Kalecik Karası red wine grape variety were studied. The midday leaf water potential thresholds were used for irrigation timing, and those values were set as -10 bars until flowering, -13 bars between the berry set-veraison and the veraison-ripening periods, and -12 bars after harvest for both irrigation treatments. Water volumes applied in the irrigations of the RDI-I plots were 50% and 75% of the cumulative evaporation from a class A pan between the berry set-veraison and veraison-ripening growth stages, respectively, while those portions for the RDI-II treatment were vice versa. The effects of control (K) and two-fold increased bud loads (2K) based on mean pruning weight on the grape yield and quality were also investigated. Irrigation and higher bud load treatments considerably increased grape yield in both years of the study. The highest and lowest grape yields were obtained in the RDI-II and the nonirrigated treatments, respectively. The increase in grape yield of irrigated vines in relation to nonirrigated ones was 53.3% in the first year and 54.3% in the second year. With doubling the bud load, the achieved increases in grape yield were 37.8% and 45.1% compared to the traditional bud loads in the first and the second year, respectively. The bud load effect was more apparent for the irrigated vines compared to the rain-fed cultivation. Cluster weight was also higher for the irrigated vines. These increases can most probably be related to improved canopy development under irrigation application. The leaf stomatal conductance was higher as a consequence of the higher soil water contents in both irrigated treatments. The improved gas exchange due to the stomatal openings led to a higher leaf area index as well as an increase in grape yield of the irrigated plants. Our findings reveal that the grape yield of the Kalecik Karası grape variety can be increased with irrigation and higher bud load applications. It is also worth noting that a limited irrigation application may help to maintain a better berry quality compared to the traditional rain-fed grape cultivation.
