Influence of deficit irrigation and kaolin particle film on grape composition and volatile compounds in Merlot grape (Vitis vinifera L.).
The effect of deficit irrigation and a kaolin-based, foliar reflectant particle film (PF) on grape composition and volatile compounds in Merlot grapes was investigated over two growing seasons in semi-arid, south-western Idaho. Vines were provided with differential amounts of water based on their estimated crop evapotranspiration (ET(c)) throughout berry development, and particle film was appli...
متن کاملRecovery and fine structure variability of RGII sub-domains in wine (Vitis vinifera Merlot).
BACKGROUND AND AIMS Rhamnogalacturonan II (RGII) is a structurally complex pectic sub-domain composed of more than 12 different sugars and 20 different linkages distributed in five side chains along a homogalacturonan backbone. Although RGII has long been described as highly conserved over plant evolution, recent studies have revealed variations in the structure of the polysaccharide. This stud...
متن کاملIrrigation and rootstock effects on the phenolic composition of Vitis vinifera L
Phenolic compounds of the skin and seeds are the principal sources of wine color and structural properties. Under semi-arid conditions, irrigation management is the most determining factor of grape and wine quality while rootstocks affect numerous physiological and vegetative parameters of the scion. In the present study, compositional changes of skin and seed phenolic compounds were studied in...
متن کاملBiological activities of Vitis vinifera L. leaves
The fractions of different polarity, namely chloroform, ethylacetate, n-butanol, and remaining water fractions, were fractionated from an aqueous extract of V. vinifera leaves. The antibacterial, antifungal, antiviral, antioxidant activities, and total phenolic content of these fractions were investigated. The chloroform fraction showed a promising effect against Herpes simplex virus type-1 (HS...
متن کاملSoil-sediment nutrient transport dynamics in a Himalayan watershed
Nutrient dynamics in the Bela watershed, Nepal were examined using a range of GIS budget modelling and field analysis techniques. The fertility status analysis showed that soil acidity, phosphorus availability, and lack of base cations were the key soil fertility issues. Nutrient budget calculations revealed significant annual phosphorus deficits for maize rota tions, but only minor deficits i...
