“…The grape yield and quality are influenced by many factors such as climatic conditions, soil chemical and physical properties variety, viticulture management practices, crop load, leaf removal, irrigation, and rootstock-scion relationship (Pachnowska and Ochmian, 2018). Among the factors affecting vine growth and development, winter pruning has the greatest impact on the grape yield and quality of the growing season due to its impact on bud fertility and nutrient reserves in grapevine (Qiu et al, 2019).…”

<p class="042abstractstekst">The aim of this study was to study the impact of crop load on the yield and grape quality of ‘Merlot’ and ‘Vranac’ (<em>Vitis vinifera</em> L.) in Trebinje vineyard. The crop load levels studied in this trial were 9 buds (V1) and 12 buds (V2) per vine at each variety trained on Lenz-Moser bilateral cordon system. The impact was determined by measurements of yield per vine and grape quality characterized by the contents of total soluble solids, titratable acidity, total phenolics, total flavonoids and by total antioxidant capacity. The measured parameters of grape quality of ‘Merlot’ and ‘Vranac’ were not influenced significantly by crop load levels. V2, compared to the V1, showed the potential for increasing grape yield only for Merlot variety under experimental conditions. The results of this study also showed a positive correlation between total phenolics/flavonoids and total antioxidant capacity of grape berries in both varieties, regardless of crop loads applied.</p>

The study was carried out during the growing season 2020 in a private orchards in the Uthmaniya village, Diyala governorate, Iraq on the two grape cultivars (Halawani and Zaitoni) to evaluate the response these cultivars to three levels of pruning( 80, 100 and 120 buds.vine-1) with a fixed number of canes (10 canes vine-1 ) and spraying with Putrescine 0, 200 and 400 mg.l-1 in the growth of the studied cultivars. The results showed that the bud load 80 buds vine -1 led to a significant increase in leaf area, chlorophyll content and content of NPK in leaf petioles, while spraying 400 mg.l-1of Putrescine recorded significant increase in leaf area, leaves dry matter percentage, chlorophyll content, and NPK content in leaf petioles, as for the cultivars, the Halawani cultivar was significantly superior to the Zaitoni cultivar in the leaf area, dry matter percentage in the leaves, chlorophyll content and phosphorous content in leaf petioles, the interaction treatments gave a significant effect on all the studied traits over untreated control treatment.

The ripening process of two grape varieties in the vineyard located in the Sandomierz region was examined. In 2015, the ‘Regent’ and the ‘Sibera’ varieties reached physiological ripeness on 30th September and 3rd October, respectively. On both harvest dates, in addition to soluble solids content, titratable acidity, and pH, the macronutrient content was also determined. In the phase of physiological ripeness, the ‘Sibera’ variety showed higher acidity (1.02 g · 100 mL−1) compared with the ‘Regent’ (0.87 g · 100 mL−1). A higher soluble solids content was found in the ‘Regent’ (20.4°Brix), and slightly lower in the ‘Sibera’ (18.1°Brix). The must of the ‘Regent’ had a higher pH (3.5). This variety also had higher macronutrient contents (K, Ca and Mg). Grapes harvested after 3 weeks (late harvest) showed higher values of sugars, pH, K, and P for both varieties. However, their titratable acidity content, and Ca and Mg contents decreased. Microscopic examination showed differences in mycelial growth of Botrytis cinerea on grape bunches for both of the varieties left for the late harvest. The mycelial growth promoted faster dehydration of the ‘Sibera’ berries. Spot chemical analyses of ‘Sibera’ berry peel performed using EDS (energy dispersive spectroscopy) showed the occurrence of elevated contents of potassium, phosphorus, sulphur, magnesium and silicon. Around skin cracks, sugar crystals as well as hard-to-identify microcrystals were formed containing potassium. On the surface of the ‘Regent’ berries, potassium, and traces of phosphorus, silicon, magnesium, sulphur and calcium were found.
