BRS Ártico is a common bean cultivar with white grains with international standard size (62 g per 100 seeds), appropriate for cultivation in the Central region of Brazil and the state of Paraná. The cycle is semi-early, the yield potential 2677 kg ha-1 and BRS Ártico has moderate resistance to rust and curtobacterium wilt.

The obtaining of a compact plant, with less vigor and high productivity, equivalent to a conventional plant, constitutes a strong tendency in the current horticulture, aiming at a raising of the fruit production at the same planted area. One of the techniques that have had success nowadays is the interstem use. This study was developed in a commercial orchard of Randon Agro Silvo Pastoril S.A. (RASIP), located in the Rio Grande do Sul state, Brazil. The purpose of this work was to evaluate the vegetative and productive development of apple trees of 'Imperial Gala' with different lengths of EM-9 interstem. The treatments consisted of five interstem lengths: 10, 15, 20, 25, 30 cm. In the seventh year of implantation the following parameters were evaluated: the height of the plant, the diameter of the 'Imperial Gala' 5 cm above the second graft point, the volume of the tree-head (height, width and length), the number of bud per branch, and the number of fruits per lineal centimeter of branch. Through this study it could be concluded that the greater interstem (30 cm) presented better indices with relation of vigor control. However, the number of fruits per lineal centimeter of branch with the interstem of 10 cm offered only significant superiority, when compared with the interstem of 30 cm. Using interstem technique allows to gather the benefits of the rootstock 'Marubakaido' and to control excessive vigour with the interstem EM-9.

O principal objetivo do processamento mínimo é fornecer produtos frescos, mantendo suas qualidades nutricionais e apresentando vida útil que possibilite sua comercialização e distribuição, além de agregar valor aos produtos (Srebernich, 2007 ). O cloro é um componente químico bastante utilizado no processamento mínimo, podendo ser adotado na segunda lavagem dos produtos vegetais, visando à redução da carga microbiana da casca, ou, na etapa de enxágue, tendo como função a redução da carga microbiana adquirida durante a manipulação das frutas (Bastos, 2006). Além do cloro, o uso do metabissulfito de sódio, que possui características antioxidantes e antimicrobianas, tem o objetivo de cessar a atividade de enzimas de escurecimento e inibir a proliferação de microrganismos (Silva et al., 2012). Desta forma, o presente trabalho objetivou avaliar a qualidade de uvas da cultivar Sweet Celebration submetidas ao processamento mínimo, assim como a efetividade de três soluções de enxágue e da intensidade de corte do pedicelo das bagas na conservação desses frutos, durante 21 dias de armazenamento refrigerado a 8ºC.

A produção de frutas de clima temperado tem crescido no Brasil, onde se inclui a macieira, que tem importância socioeconômica para as regiões produtoras do Brasil, principalmente nos estados do Rio Grande do Sul, Santa Catarina e Paraná. Adaptação dessas espécies de clima temperado em condições de clima com temperaturas mais amenas e com scilações de temperatura nas regiões produtoras depende de programas de melhoramento genético. Fachinello et al. (2011). A cultivar ?Julieta?, apresenta grande potencial para produção em regiões de clima temperado, com temperatura mais amenos, é uma cultivar precoce que reque uma menor quantidade de frio para se desenvolver. Lopes et al. (2012). O presente trabalho foi desenvolvido com o objetivo de avaliar produção de frutos da macieira ?Julieta?, em função a fertirrigação nitrogenada e potássica no semiárido.

To test the hypothesis that the plant stress related elicitor cis-jasmone (cJ) provides protection in soybean pods against the seed-sucking stink bug pest, Euschistus heros, the growth of E. heros on cJ-treated pods was investigated using three soybean cultivars differing in insect susceptibility, i.e. BRS 134 (susceptible), IAC 100 (resistant) and Dowling (resistant). E. heros showed reduced weight gain when fed cJ-treated Dowling, whereas no effect on weight gain was observed when fed other treated cultivars. Using analysis of variance, a three factor (cultivar x treatment x time) interaction was observed with concentrations of the flavonoid glycosides daidzin and genistin, and their corresponding aglycones, daidzein and genistein. There were increases in genistein and genistin concentrations in cJ-treated Dowling at 144 and 120 h post treatment, respectively. Higher concentrations of malonyldaidzin and malonylgenistin in Dowling, compared to BRS 134 and IAC 100, were observed independently of time, the highest concentrations being observed in cJ-treated seeds. Levels of glycitin and malonylglycitin were higher in BRS 134 and IAC 100 compared to Dowling. Canonical variate analysis indicated daidzein (in the first two canonical variates) and genistein (in the first only) as important discriminatory variables. These results suggest that cJ treatment leads to an increase in the levels of potentially defensive isoflavonoids in immature soybean seeds, but the negative effect upon E. heros performance is cultivar-dependent.
