Different soil types can significantly affect the composition of wine grapes and the final wine product. In this study, the effects of soil types on the composition of Cabernet Sauvignon grapes and wine produced in the Helan Mountains were evaluated. Three different representative soil types--aeolian, sierozem and irrigation silting soil were studied. The compositions of grapes and wines were m...

• We know that aromatic compounds from the grapes themselves are important for quality and regional character. But whereas some varieties (like the Muscats) produce musts with similar aromas to those of the resulting wines, the musts of the majority of varieties are practically odorless. This is true for Merlot, Cabernet Sauvignon, Syrah, Sauvignon blanc, Semillon, Pinot noir, Gamay, Chardonnay...

This paper explores the characteristics of the anthocyanin and flavonol composition and content in grapes from plants resulting from intraspecific crosses of Vitis vinifera varieties Monastrell × Cabernet Sauvignon, Monastrell × Syrah, and Monastrell × Barbera, in order to acquire information for future breeding programs. The anthocyanin and flavonol compositions of twenty-seven hybrids bearing...

In wine technology redox potential represents fast, accurate and reliable measurement which results give an insight into oxidation as well as reduction ability of wine, its alteration and its influence on quality and stability. Wine as the fermentation product express a reductive character related towards the oxidation. The majority of top quality wines express very low redox potential characte...

A nuclear magnetic resonance (NMR) probe and spectrometer capable of investigating full intact wine bottles is described and used to study a series of Cabernet Sauvignons with high resolution 1H NMR spectroscopy. Selected examples of full bottle 13C NMR spectra are also provided. The application of this full bottle NMR method to the measurement of acetic acid content, the detection of complex s...

In this study, five biologically phenolic antioxidant Turkish red wines from different regions of Turkey were determined using HPLC with PDA detection. The antioxidant capacities (AC) of the investigated wines are also determined and the relationship between the phenol content and antioxidant capacity is discussed. The results show that Kalecik Karasi, Merlot and Cabernet Sauvignon AC values ra...

A field experiment was established in a second-growth hardwood forest dominated by red oak (Quercus rubra L.) to examine the effects of shelterwood overstory density on leaf gas exchange and seedling water status of planted red oak, naturally regenerated red oak and sugar maple (Acer saccharum Marsh.) seedlings during the first growing season following harvest. Canopy cover of uncut control sta...

Septoria leaf blotch caused by Zymoseptoria tritici is one of the most harmful diseases in Belarus. Isolates pathogen were obtained from northern, central and southern populations: 2018–2019, whichvaried significantly among structure colonies. The rate fungal isolates forming yeast-like colonies decreased 55.0 % North Belarus to 6.7 South, whereas incidence filamentous increased 31.3 80.0 %, re...

Abstract Breeding of multi-resistant varieties to reduce yield loss due disease damage and lodging, reduction input intensity are high importance for a more sustainable cereal production. The aim this study was evaluate (i) caused by diseases lodging (ii) impact soil fertility in variety trials grown under two intensities. Intensity 2 treated with 1 without fungicides growth regulators. We appl...
