“…The hybrids IAC 514-6 (ID: 46) and IAC 514-6 (Maria) (ID: 47) shared the same name but not the same genetic profile. In the literature, this variety has been described as a seedless white table grape (Pommer, 1993;Pommer et al, 1995), and according to IAC phenotyping data (unpublished), only the IAC 514-6 (Maria) (ID: 47) genotype matches these descriptions. Both genotypes corresponded to white table grapes, but only IAC 514-6 (Maria) (ID: 47) was a seedless grape, and the other presented well-developed seeds.…”

“…No Chile, Muñoz & Pezoa (1993) observaram, na variedade Superior Seedless, que a combinação de ácido giberélico e anelamento promoveu maior produção, peso de cachos, peso dos engaços e diâmetro de bagas. No Brasil, resultados semelhantes foram obtidos em outras variedades por diversos autores (Castro et al, 1974;Pereira & Oliveira, 1976;Pereira et al, 1979;Guerra et al, 1981;Maraschin et al, 1986;Pires et al, 1986;Pommer et al, 1995).…”

RESUMO -Com o objetivo de se obter maior tamanho de baga, peso médio de cacho e produtividade, os cachos da variedade Superior Seedless foram pulverizados com ácido giberélico (1 + 20 mg.L -1 ), bioestimulante Crop Set nas doses de 0,1 e 0,2% e com ou sem anelamento no caule. Esses tratamentos foram aplicados de forma isolada ou combinados entre si. O trabalho foi conduzido durante o período 2001-2002 (dois ciclos de produção), no Campo Experimental de Bebedouro da Embrapa Semi-Árido em Petrolina-PE. O delineamento experimental foi em blocos ao acaso, com 12 tratamentos e três repetições, sendo duas plantas por parcela. Não foram observadas diferenças significativas entre os tratamentos nos dois ciclos de produção. Entretanto, quando o ácido giberélico foi associado ao Crop Set 0,1% e anelamento, observou-se uma tendência de aumento no peso de cachos, bem como no peso e tamanho de bagas na safra de 2001. Os cachos tratados com ácido giberélico apresentaram engaços mais grossos e pesados, embora não se observem diferenças significativas entre os tratamentos. Algumas plantas submetidas ao anelamento apresentaram problemas de cicatrização, o que provocou a morte das mesmas, recomendando-se evitar a realização desta prática nas condições em que se realizou este trabalho.

Superior Seedless was powdered with gibberelic acid (1 + 20 mg.L -1 ), bio-stimulant Crop Set in the dosis of 0.1 and 0.2%. In adition was used the treatment known as girdling. Those treatments were applied in an isolated way or combined to each other. The work was carried out during 2001-2002 (two harvest seasons), in the Experimental Station of Bebedouro, Semi-arid Embrapa in Petrolina, Pernambuco State. The experimental design were in randomized blocks with 12 treatments and three replications. The differences among the treatments were not statistical significant in the two evaluated seasons. However, when the gibberelic acid was associated with Crop Set 0.1% and girdling, it was observed a tendency to increase the weight of bunches, as well as, the weight and berry size in the 2001 season. The bunches treated with gibberelic acid presented stronger rachis, although significant differences are not observed among the treatments. Some plants submited to the girdling presented problems with cicatrization, that caused death of them, recomending to avoid this practice in the conditions of this work.

“…O autor observou que o diâmetro final dos bagos foi maior à medida que se aumentou a concentração de ácido giberélico aplicado juntamente com o anelamento. Pommer et al(1995), estudaram o efeito da incisão anelar, de forma isolada ou em conjunto com ácido giberélico, sobre os cachos e os bagos da cultivar apirena Maria, na região de Jundiaí. O anelamento e o ácido giberélico aumentaram significativamente o número, a massa, o comprimento e a largura dos bagos, e a massa, o comprimento e a largura dos cachos, em comparação com a testemunha.…”

“…Assim, visando a redução de custos, o produtor pode optar pela aplicação isolada do ácido giberélico. Tais resultados diferem daqueles obtidos porPommer et al (1995), que constataram efeito superior do anelamento mais a aplicação do ácido giberélico sobre a massa, o comprimento, a largura dos cachos; número, massa, comprimento e largura de bagos, em relação ao anelamento ou a aplicação do regulador vegetal feitos isoladamente. O delineamento experimental foi em blocos ao acaso com 18 tratamentos e 5 repetições no esquema fatorial 2x9.…”

The present work was developed to evaluate the effect on the cluster, berries and raquis characteristics of Niagara Rosada and Venus table grapes of increasing doses of gibberellic acid associated or not with branch girdling and/or cluster blunt. Two experiments, for each cultivar, were accomplished in the northwest area of São Paulo State, Brazil, in a randomized block design, with five replications, being fourteen and eighteen treatments for 'Niagara Rosada' and twenty-eight treatments for 'Venus'. The gibberellic acid in the doses of 0; 10; 22,5; 35; 47,5; 60 and 72,5ppm, was applied, through the total immersion of the clusters, fifteen days after the full flowering, except for the second experiment with 'Niagara Rosada', in which was added up two more doses of 85 and 97,5ppm. The girdling in the productive branches was also accomplished in this same time. In the first experiment with 'Niagara Rosada' no effect of girdling was detected on the berry mass and size. Also, gibberellic acid (35ppm) alone increased cluster and berry mass and size. This same dose when associated with girdling provided increase in the soluble solids. In the second experiment with 'Niagara Rosada', larger increments on berry size and mass, as well as, pedicels diameter were obtained with gibberellic acid (60ppm) associated with branch girdling. The largest increments on cluster mass and width and on the berry number per cluster, were xi obtained applying gibberellic acid (35ppm) associated with girdling. In the first experiment with 'Venus' seedless table grape in 1999 it was detected that the higher the concentrations of gibberellic acid, the larger were berry length, width and the mass. Also, girdling associated or not with cluster blunt increased these same characteristics. In the second experiment with 'Venus' cultivar it was noticed that the higher the concentrations of gibberellic acid, the larger were cluster and raquis length and width. Gibberellic acid (35ppm) associated with girdling only or with cluster blunt provided the largest increase on cluster and raquis masses and the largest berry number per cluster. Larger berries were obtained with gibberellic acid (60ppm) associated with girdling only or with cluster blunt. The largest berry mass was obtained with gibberellic acid (47,5ppm). Also, it was detected a decrease in soluble solids with higher concentrations of the vegetable regulator associated with girdling.
