Research ArticleOpen accessPhrase in the titleAntioxidant and Antimutagenic Activities of Taif Grape (Vitis vinifera) CultivarsAbdelmegid Ibrahim Fahmi, Mohamed Ahmed Nagaty, Ahmed Mohamed El-ShehawiExtract of grape Vitis vinifera has been reported to exhibit antioxidant and antimutagenic activities and the phenolic compounds play a vital role in determining these activities. Therefore; the objective of the present study was to evaluate the antioxidant and anti-mutagenic activities as well as the phenolic composition of different grape cultivar extracts collected from Taif region. The grape cultivars namely; … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 2 · 20 Jun 2013 · 8,010 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleEffect of Elicitors and Precursors on the Synthesis of Anthocyanin in Grape Vitis vinifera Cell CulturesNay Min Min Thaw Saw, Heidi Riedel, Onur Kütük et al.Problem statement: Nowadays, plant cell suspension cultures and immobilized cells are being utilized for the higher yield and quality of the products than extraction of whole plants. Anthocyanins are compounds found in plants that have powerful antioxidant properties. They also provide some of the coloring or pigment of plants, flowers and fruits. Anthocyanin from grape cell cultures can be used … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 15,277 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleManipulation of Photosynthesis in Grape (Vitis vinifera) CV. ‘Flame’ by the Application of Two Sucrose AnalogsM. E. Tiznado-Hernandez, J. A. Orozco-Avitia, A. J. Ojeda-Contreras, A. A. Gardea-BejarThe translocation of photosynthates from the leaves is important for the accumulation of sugars in grape berries. Two sucrose analogs were applied at post-veraison to determine their effects on leaf photosynthesis. It is hypothesized that the signal of sugar accumulation in leaves will bring a reduction in photosynthesis and an increase in the photosynthate translocation rate to the berries. The … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 1 · 9 Feb 2013 · 7,927 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleNon-Alcoholic, Naturally-Carbonated Beverage from Vitis Vinifera Using Saccharomyces Cerevisae Isolated from Cheese WheyHeena Chilana, Sanju Arora, Robinka Khajuria, Loveleen KaurIn the present work a pure yeast culture was isolated from cheese whey and identified by 26S rDNA sequencing as Saccharomyces cerevisiae NRRL Y-12632. This yeast was used to produce low alcoholic self carbonated beverage from grape juice, grape: Kinnow juice (2:1) and grape: Pomegranate juice (2:1) under optimized conditions. The physicochemical properties of 3 days fermented grape: Pomegranate beverage … …OnLine Journal of Biological Sciences, Vol. 15, Issue 3 · 6 Aug 2015 · 7,148 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleGenetic Variability in Rhizoctonia solani Isolated from Vitis vinifera Based on Amplified Fragment Length PolymorphismAmparo Meza-Moller, Martin Esqueda, Felipe Sanchez-Teyer et al.Problem statement: Rhizoctonia solani is a potential grapevine pathogen. In order to develop effective methods of control, it is necessary to document its genetic diversity. Approach: The objective of this study was to analyze the genetic variability of R. solani isolated from the rhizosphere of ungrafted V. vinifera var. perlette seedless planted in Sonora, Mexico using Amplified Fragment Length Polymorphism … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 4 Aug 2011 · 8,477 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsComparative Leaf Anatomy of Selected Species in Vitaceae and LeeaceaeChnar Najmaddin, Khatijah Hussin, Haja MaideenLeea species was originally placed in the family Vitaceae but was later placed in the Leeaceae due to the anatomical differences between the two families and between species. A study on the anatomical difference in leaves of four species in the Vitaceae (Tetrastigma cruciatum, Pterisanthes miquelii, Cissus hastata and Nothocissus spicifera) and two species from Leeaceae (Leea rubra and Leea … …American Journal of Applied Sciences, Vol. 10, Issue 4 · 28 Apr 2013 · 7,395 accessesView PDF Cite

EditorialOpen accessIn the abstractThe Timeless Contribution of Rootstocks towards Successful Horticultural Farming: From Ancient Times to the Climate Change EraIoannis E. PapadakisGrafting is a horticultural practice by which living vegetative plant organs (root, stem and/or buds) of either the same genotype or, usually, different genotypes belonging to the same species, genus, subfamily and/or family, are tightly connected to each other to form a double-compound plant. In fact, it is a method of asexual (clonal-vegetative) propagation of plants. The basal part of … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 16 Dec 2016 · 9,521 accessesView PDF Cite
