Anatomy, chlorophyll content and photosynthetic potential in grapevine leaves under plastic cover Rev. Bras. Frutic.
Chavarria,Geraldo; Santos,Henrique Pessoa dos; Castro,Luis Antônio Suita de; Marodin,Gilmar Arduíno Bettio; Bergamaschi,Homero.
The present study evaluated the anatomy, chlorophyll content and photosynthetic potential of grapevine leaves grown under plastic cover. The experiment was carried out in vineyards of Moscato Giallo cultivar covered and uncovered with plastic. A block design with 10 selected plants was used for each area (covered and uncovered). Twelve leaves (six of them fully exposed to solar radiation and six grown under shaded conditions) were collected from each area and were fixed and analyzed microscopically (thickness of the adaxial and abaxial epidermis and of the palisade and spongy parenchymas). Chlorophyll content and photosynthetic potential were determined in the vineyard at veraison and after harvest. Plastic covering increased the thickness of the palisade...

Comparative transcriptome analyses between cultivated and wild grapes reveal conservation of expressed genes but extensive rewiring of co‑expression networks. Repositório Alice
FAJARDO, T. V. M.; QUECINI, V..
Key message The transcriptomes of wild and cultivated grapes consists of similar expressed genes but distinct wiring of co-expressed modules associated with environmental conditions. Abstract Grapevine is an important fruit crop worldwide, with high economic value and widespread distribution. Commercial production is based on Vitis vinifera, and, to a lesser extent, on hybrids with American grapes, such as V. labrusca. Wild grape relatives are important sources of resistance against biotic and abiotic factors; however, their global gene expression patterns remain poorly characterized. We associated genome-wide transcript profling to phenotypic analyses to investigate the responses of cultivated and wild vines to vineyard conditions. The expressed genes in...

Diabrotica speciosa (Ger.) (Coleoptera: Chrysomelidae): New Pest in Table Grape Orchards Neotropical Entomology
ROBERTO,SÉRGIO R.; GENTA,WERNER; VENTURA,MAURÍCIO U..
We report for the first time the occurrence of Diabrotica speciosa (Ger.) damaging blooming clusters in grapevine orchards in Northwest Paraná State. On middle September, 2000, insects were found feeding on style, stigma and eventually on ovary. Up to 15 adults per cluster were observed. Insects feeding on stigma caused flowers aborting. In high population areas, clusters showed low number of fruits and were out of market standards.

Do cover crops compete with young grapevines for fertilizer nitrogen? Repositório Alice
BRUNETTO, G.; CERETTA, C. A.; MELO, G. W. B. de; FELIPE, L.; PAULO, A. A. F.; COUTO, R. da R.; SILVA, L. O. S.; SOMAVILLA, L. M.; ADRIELE, T.; GARLET, L. P.; LESSANDRO, D. C.; COMIN, J. J.; LOVATO, P. E..
Vineyard soils of the Campanha Gaúcha region of Rio Grande do Sul are sandy and have low to medium organic matter content, displaying low natural ability to supply nitrogen (N). Therefore, maintenance of cover crops is essential or the protection of the soil surface from the impact of raindrops and water erosion. The application of nitrogen fertilizers is also necessary. However, cover crops can absorb part of the nitrogen applied in the soil, decreasing the availability to young vines, which may slow the growth of root and shoot, and thus, the beginning of grape production.

SIQUEIRA, P. R. E.; BOTTON, M.; BAYER SIQUEIRA, P. R.; PERES, G. S.; SOARES, L. da L..
The southernmost region of the state of Rio Grande do Sul, Brazil, has emerged as one of the major poles for fine grape production (Vitis vinifera) for wine processing. In this region, grapevine rust mite (Calepitrimerus vitis) is one of the major pests for the culture; however, information is lacking about production losses caused by this species and acaricides for its control. In this paper, the acaricide effect of azadarachtin, boron + nitrogen on orange peel oil, sulfur and spirodiclofen on C. vitis on Merlot cultivar commercial grapevine was evaluated and production losses caused by the presence of the mite were estimated. The experiment was conducted during the 2012/2013 and 2013/2014 growing seasons, comparing the infestation levels of C. vitis and...

Expression of Grapevine leafroll-associated virus 3 coat protein gene in Escherichia coli and production of polyclonal antibodies Trop. Plant Pathol.
Fajardo,Thor V.M.; Barros,Danielle R.; Nickel,Osmar; Kuhn,Gilmar B.; Zerbini,F. Murilo.
Grapevine leafroll-associated virus 3 (GLRaV-3), the main viral species of the grapevine leafroll complex, causes yield and quality reduction in grapes (Vitis spp.). The coat protein gene was RT-PCR-amplified from total RNA extracted from infected grapevine leaves and the amplified fragment was cloned and completely sequenced. The fragment was subsequently subcloned into the pRSET-C expression vector. The recombinant plasmid was used to transform Escherichia coli BL21:DE3 and express the capsid protein. The coat protein, fused to a 6 His-tag, was purified by affinity chromatography using an Ni-NTA resin. The identity of the purified protein was confirmed by SDS-PAGE and Western blot. The in vitro-expressed protein was quantified and used for rabbit...

Garlic extract improves budbreak of the 'Niagara Rosada' grapevines on sub-tropical regions Ciência Rural
Botelho,Renato Vasconcelos; Pires,Erasmo José Paioli; Moura,Mara Fernandes; Terra,Maurilo Monteiro; Tecchio,Marco Antonio.
In the regions with mild winters, usually the chilling requirements for bud dormancy release of grapevines are not fulfilled, and only the highly toxic products CaCN2 (calcium cyanamide) and H2CN2 (hydrogen cyanamide) are recommended in conventional viticulture for budbreak. The purpose of this study was to verify the effect of garlic extract on budbreak of 'Niagara Rosada' grapevines in two different vineyards. The highest dose of garlic extract (70mL L-1) showed a great potential for budbreak in organic production, presenting similar effects of cyanamides in budbreak. This treatment improved the sprouting percentage, number of clusters, accelerated the beginning of sprouting and reduced the cycle between pruning and harvest.

Genetic changes in grapevine genomes after stress induced by in vitro cultivation, thermotherapy and virus infection, as revealed by AFLP Genet. Mol. Biol.
Baránek,Miroslav; Raddová,Jana; Krizan,Bretislav; Pidra,Miroslav.
The Amplification Fragment Length Polymorphism (AFLP) technique was employed to study genetic variations which can be induced in vines by the stress occurring during different aspects of viticulture (in vitro cultivation, in vitro thermotherapy and virus infection). Analysis of AFLP banding patterns, generated by using 15 primer combinations, pointed to negligible genetic variation among plants exposed to individual stress. The average of similarity coefficients between differently stressed plants of the cultivars Müller Thurgau and Riesling were 0.984 and 0.991, respectively, as revealed by AFLP analysis. The low incidence of observed polymorphism demonstrates the high level of genome uniformity in plants reproduced by in vitro micropropagation via nodes,...
