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...

Characterization of an early berry development grapevine somatic variant (Vitis labrusca L. cv. Isabel Precoce). Repositório Alice
PASSAIA, G.; MARGIS-PINHEIRO, M.; FIALHO, F. B.; SBEGHEN, F.; PORTO, D. D.; REVERS, L. F..
Over the past 10 years significant advances have been made towards the description of genetics and molecular mechanisms controlling grapevine berry growth. Regardless of this, many aspects of early fruit morphogenesis and its development control remain to be elucidated. In an attempt to understand gene expression patterns associated with the berry growth development, the contrasting phenotype between the cv. Isabel (Vitis labrusca L.) and its early berry development mutant ?Isabel Precoce? has been explored by a candidate gene approach. ?Isabel Precoce? (Vitis labrusca L.) was confirmed as an EDV (Essentially Derived Variety) of Isabel, with a 30 - 35-day reduction in the berry growth phase when compared to the wild type and thus, it constitutes an...

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.

Evaluation of insecticides for the control of Linepithema Micans (Hymenoptera: Formicidae). Repositório Alice
NONDILLO, A.; CHAVES, C. C.; FIALHO, F. B.; BUENO, O. C.; BOTTON, M..
Linepithema micans (Forel) (Hymenoptera: Formicidae) is the main ant species responsible for the spreading of Eurhizococcus brasiliensis (Wille) (Hemiptera: Margarodidae), a soil scale that damages grapevine plants in southern Brazil. The effect of contact and ingestion of insecticides on the control of L. micans was evaluated in a greenhouse using grapevines (Vitis spp.) infested by L. micans. The insecticides thiamethoxam (250, 187.5, and 125 g/ha), Þpronil (4, 5, and 50 ml/ha), and imidacloprid (650 g/ha) were sprayed on the ground, whereas toxic baits containing boric acid (0.5, 1.0, and 1.2%), pyriproxyfen (0.3 and 0.5%), and hydramethylnon (0.5%) were evaluated in different formulations. Hydramethylnon (toxic bait) and thiamethoxam (chemical barrier)...

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...

Foraging activity and seasonal food preference of Linepithema micans (Hymenoptera: Formicidae), a species associated with the spread of Eurhizococcus brasiliensis (Hemiptera: Margarodidae). Repositório Alice
NONDILLO, A.; FERRARI, L.; LERIN, S.; BUENO, O. C.; BOTTON, M..
Linepithema micans (Forel) (Hymenoptera: Formicidae) is the main ant species responsible for the spread of Eurhizococcus brasiliensis (Wille) (Hemiptera: Margarodidae), a soil scale that damages vine plants in southern Brazil. The daily foraging activity of L. micans and its seasonal preference for protein- and carbohydrate-based foods were evaluated. The study was carried out in a greenhouse using seedlings of the Paulsen 1103 rootstock (Vitis berlandieriVitis rupestris) planted individually in pots and infested with colonies of L. micans. To determine the daily foraging activity and seasonal preference, a cricket (Gryllus sp.) and a 70% solution of inverted sugar and water were offered once a month for 12 mo. The ants foraging on each food source were...

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,...

Genetic diversity in table grapes based on RAPD and microsatellite markers. Repositório Alice
LEAO, P. C. de S.; MOTOIKE, S. Y..
The objective of this work was to analyze the genetic diversity of 47 table grape accessions, from the grapevine germplasm bank of Embrapa Semiárido, using 20 RAPD and seven microsatellite markers. Genetic distances between pairs of accessions were obtained based on Jaccard's similarity index for RAPD data and on the arithmetic complement of the weighted index for microsatellite data. The groups were formed according to the Tocher's cluster analysis and to the unweighted pair-group method with arithmetic mean (UPGMA). The microsatellite markers were more efficient than the RAPD ones in the identification of genetic relationships. Information on the genetic distance, based on molecular characteristics and coupled with the cultivar agronomic performance,...
