Antispila sp. minatore fogliare segnalato in Italia su vite = Antispila sp. a new leafminer of grapes in Italy Naturalis
Baldessari, M.; Angeli, G.; Girolami, V.; Mazzon, L.; Nieukerken, E.J. van; Duso, C..
Two leaf-miner species occur in European vineyards, i.e. Holocacista rivillei (Stainton) (Lepidoptera Heliozelidae) and Phyllocnistis vitegenella Clemens (Lepidoptera Phyllocnistidae). In the summer of 2007, leaf mines similar to those caused by H. rivillei were observed in a vineyard located in north-eastern Italy. However, the first portion of mines (linear tortuous) was lacking and thus the occurrence of a different species was suspected. Larvae were reared in controlled conditions to obtain adults and the latter differed from those of H. rivillei because of their size and wing patterns. Adults belonged to the genus Antispila Hübner, but not to the species of this genus currently known for Italy and Europe. Antispila sp. was detected for the first time...

Leão,Patrícia Coelho de Souza; Cruz,Cosme Damião; Motoike,Sérgio Yoshimitsu.
The purpose of this research was to study the genetic diversity and genetic relatedness of 60 genotypes of grapevines derived from the Germplasm Bank of Embrapa Semiárido, Juazeiro, BA, Brazil. Seven previously characterized microsatellite markers were used: VVS2, VVMD5, VVMD7, VVMD27, VVMD3, ssrVrZAG79 and ssrVrZAG62. The expected heterozygosity (He) and polymorphic information content (PIC) were calculated, and the cluster analysis were processed to generate a dendrogram using the algorithm UPGMA. The He ranged from 81.8% to 88.1%, with a mean of 84.8%. The loci VrZAG79 and VVMD7 were the most informative, with a PIC of 87 and 86%, respectively, while VrZAG62 was the least informative, with a PIC value of 80%. Cluster analysis by UPGMA method allowed...

Effects of shading on leaf physiology and morphology in the ‘Yinhong’ grape plants Rev. Bras. Frutic.
Wu,Yueyan; Qiu,Tian; Shen,ZiLi; Wu,Yanyan; Lu,Dan; He,Jingwen.
Abstract Shading is a practical measure to reduce the heat stress to grape trees in the summer. However, inappropriate shading will cause the reduction in leaf photosynthesis and consequently the retardation of growth for the plants or the loss of fruit yield and quality for the mature grape trees. In this study we have used 1-year-old ‘YinHong’ grape plants growing under different levels of shading, ranging from full sunlight 0% to 80% reduction, to investigate their growth, physiological and biochemical responses. The results show that shading rate =45% did not significantly affect grape growth. Shading over 45% reduction of the full sunlight, the growth of the grape plants were started to be inhibited. In addition, soluble protein content, the...

Efficient protocol for isolation of functional RNA from different grape tissue rich in polyphenols and polysaccharides for gene expression studies Electron. J. Biotechnol.
Vasanthaiah,Hemanth K.N.; Katam,Ramesh; Sheikh,Mehboob B.
Extraction of RNA from plant tissue containing high levels of polyphenols and polysaccharides is tedious and difficult in grapes. Although several protocols have been published for plant RNA isolation, most have failed to yield high quality RNA in sufficient quantity from mature and diseased grape tissue. We describe a protocol for isolating intact and high quality RNA from various grape tissues as evident by high A260/A280 absorbance ratio (1.8 to 1.9) and electrophoretic profile on denaturing formaldehyde agarose gel. On an average, 205 µg RNA per g of fresh tissue were obtained using this modified protocol. RNA quality was further assessed through RT-PCR, differential display RT-PCR and subtractive hybridization, and found to be suitable for molecular...

Foliar carbohydrates content and invertase activity in vines at São Francisco River Valley - Brazil Rev. Bras. Frutic.
Dantas,Barbara França; Ribeiro,Luciana de Sá; Silva,Alexandro Pereira da; Luz,Sara Raquel de Souza.
The irrigated agriculture at the São Francisco River Valley, Northeast Brazil, shows an increasing production of grapes for winery. Among the wines produced there the one obtained from Vitis vinifera L., cultivar Syrah, stands out due to its adaptation to the climatic conditions of the region. However, little is known about carbohydrates metabolism of vines cultivated in this region. The objective of this work was to evaluate sugar and starch contents and the invertase activity in vines leaves during two consecutive growing seasons. The experiment was carried out at Embrapa Semi-Árido and at Santa Maria Winery, respectively located in Petrolina and Lagoa Grande, Pernambuco-Brazil. Leaves were collected weekly from January to December of 2003 and assessed...

Genetic diversity of table grape based on morphoagronomic traits Scientia Agricola
Leão,Patrícia Coelho de Souza; Cruz,Cosme Damião; Motoike,Sérgio Yoshimitsu.
The conservation and characterization of grape (Vitis spp) genetic resources in germplasm banks have been the basis of its use in breeding programs that result in development of new cultivars. There are at least 10,000 grape cultivars kept in germplasm collection. The genetic diversity in 136 table grape accessions from the state of Bahia, Brazil, was evaluated. Continuous and discrete morphoagronomic traits were assessed. The clustering analysis by the Tocher otimization method resulted in 30 clusters (considering continuous morphoagronomic traits), and 9 clusters (taking into consideration multicategorical traits). There was no agreement between clusters obtained by both, continuous or discrete phenotypic descriptors, independent of the cluster method...

Grape quality mapping for vineyard differential harvesting BABT
Santos,Antonio Odair; Wample,Robert L.; Sachidhanantham,Sivakumar; Kaye,Oren.
An experiment was carried out from 2005 to 2008, to calibrated NIR-based instrumentation and explore within field grape quality variability and map potential grape quality descriptors along vineyards, as a subsidy for differential harvesting,. The quality indicators (anthocyanin content, pH, titratable acidity and soluble solids) were subject to geo-spatial modeling. Subsequently, the data set was utilized to delineate "within-field" grape quality zone and to determine the timing of the harvest. Differential machine harvesting was implemented and segregation of wine grapes was done "on-the-go". The approach for field prediction of grape quality parameters and zone delineation allowed for separated fermentation for at least two wine styles.

HEAVY METALS AND MICRONUTRIENTS IN THE SOIL AND GRAPEVINE UNDER DIFFERENT IRRIGATION STRATEGIES Rev. Bras. Ciênc. Solo
Oliveira,Vanessa de Souza; Lima,Augusto Miguel Nascimento; Salviano,Alessandra Monteiro; Bassoi,Luís Henrique; Pereira,Giuliano Elias.
Soils under natural conditions have heavy metals in variable concentrations and there may be an increase in these elements as a result of the agricultural practices adopted. Transport of heavy metals in soil mainly occurs in forms dissolved in the soil solution or associated with solid particles, water being their main means of transport. In this context, the aim of this study was to evaluate the heavy metal and micronutrient content in the soil and in the grapevine plant and fruit under different irrigation strategies. The experiment was carried out in Petrolina, PE, Brazil. The treatments consisted of three irrigation strategies: full irrigation (FI), regulated deficit irrigation (RDI), and deficit irrigation (DI). During the period of grape maturation,...

Intralaboratory optimization and validation of a method for patulin determination in grapes by Thin-Layer Chromatography BJM
Oliveira,Renata Cabrera de; Bando,Érika; Machinski Junior,Miguel.
The aim of this work was to optimize and validate, by intralaboratorial procedures, a method for the determination of patulin in grapes by thin-layer chromatography. The steps of extraction, cleanup, detection and quantification were optimized. For the validation of the method, recovery assays with standard solutions and artificially contaminated samples were carried out. The mean recovery and the variation coefficient were 65.4% and 7.58%, respectively. The optimized conditions were: 50 mL of grape juice, three extraction stages (with 100 mL of ethyl acetate in the first stage and 50 mL in second and third stages), and 100 µL of ethanol to solubilize the extract. The solvent-system used was toluene - ethyl acetate - formic acid (6:3:1), and 0.5% MBTH in...

Melatonin treatment of pre-veraison grape berries modifies phenolic components and antioxidant activity of grapes and wine Ciênc. Tecnol. Aliment.
MENG,Jiang-Fei; YU,Yong; SHI,Tian-Ci; FU,Yu-Shi; ZHAO,Ting; ZHANG,Zhen-Wen.
Abstract A comprehensive investigation was conducted to determine the effects of exogenous melatonin treatment of pre-veraison grapes on phenolic components and antioxidants of grape berries and wine. The results showed an increase in the concentration of cyanin-3-O-glucoside, peonidin derivatives, and two flavanols [namely (+)-catechins and (−)-epicatechins] of grapes, as well as flavonols in both grapes and wine due to the application of melatonin. These compounds are derivatives of the catalysate of flavonoid 3’-hydroxylase (F3’H) in the flavonoid synthesis pathway of plants. It can be inferred that melatonin increased the activity of F3’H or expression of VvF3’H during grape berry maturation. In addition, two melatonin treatments of pre-veraison grape...
