Firmeza de polpa e aceitabilidade como parâmetros para indicação do amadurecimento de peras 'Abate Fetel'.

Dada à importância do estabelecimento de parâmetros relacionados ao amadurecimento, este trabalho teve por objetivo avaliar a firmeza de polpa e a aceitabilidade como parâmetros para indicar o amadurecimento e a qualidade ótima para consumo de peras 'Abate Fetel'.

Manual cross-pollination, fruit set and development in pear.

The lack of pear-compatible rootstocks in Brazil calls for the application of classical genetic techniques. Therefore, in order to obtain select suitable material, the search for genetic segregation must be continuous, being used as alternative scion cultivars. This study aims to assess fruit set, number of seeds, fruit weight and fruit diameter according to crosses between pear cultivars. The trial was carried out from September 2008 to February 2009 in a commercial orchard in the city of Vacaria/RS, Brazil. For the pollination process, pollen was extracted from flowers at full-white stage in the same orchard. The cultivars used were 'Packham's Triumph' and 'Clapps Favorite'. The crossings were defined as: open pollination; selfpollination of 'Packham's Triumph' and 'Packham's Triumph' × 'Clapps Favorite'. The pollinations were done manually in flowers at full-white stage, which were opened, emasculated and then pollinated. Each pollinated flower was then isolated with a fine nylon bag. Open pollination and cross pollination between 'Packham's Triumph' × 'Clapps Favorite' provided higher fruit set (17 and 18%, respectively). Fruit weight and diameter did not differ between treatments. Open pollination provided fruits with a higher number of seeds.

Maturity index and cold storage effects on postharvest quality of 'Packham's Triumph' and 'Rocha' pears.

Pears have been grown in the south region of Brazil, where the climatic conditions are favourable. The aim of this work was to determine the harvest maturity index as well as maximum storage period of 'Packham's Triumph? and 'Rocha' pears to maintain quality attributes. The ?Packham?s Triumph? fruit were harvested from a commercial orchard at 7 days intervals and flesh firmness was used as a maturity index (MI1=76, MI2=67 and MI3=58 N). ?Rocha? pears were harvested twice and they were considered as MI1 and MI3 because of the firmness values. The fruit were stored at 1±1C and 90-95% RH for 15, 30, 45 and 60 days and evaluated at the end of each storage period and after five days at room temperature (24±1C), simulating a helflife period. Flesh firmness, water loss, peduncle dehydration, epidermis colour, soluble solids, titratable acidity were measured. ?Packham?s? pears harvested at MI1 and MI2 showed firmness loss after 30 days of cold storage, whereas fruit harvested at MI3 retained the initial values, resulting in firmer fruit after 60 days (P<0.001). Fruit harvested in MI3 had less firmness loss after 5 days at room temperature following 45 and 60 days of cold storage. ?Rocha? pears harvested in MI1 and MI3 showed firmness reduction during cold storage, which was intensified at room temperature. Maximum values of water loss approached 6%. Fruit peduncles of both cultivars dehydrated after 60 days of cold storage, but their colour remained green, independent of harvest maturity index. ?Packham?s Triumph? and ?Rocha? pears harvested at MI3 showed better quality attributes after 60 days of cold storage plus 5 days of shelf-life than fruit harvested at other maturity stages.

THE INTERTEXTUALITY OF OPERA IN THE FICTION OF NELIDA PIÑON

This article examines how Nélida Piñon builds a feminist reader in the novel A força do destino (1978). This work highlights the role of the contemporary writer to read the classics from the post-modern and feminist places. Post-modern because it decentralizes the structural elements of the text, feminist because it opposes to any kind of women oppression. In this novel, the narrator reconstructs the trajectory of the characters Alvaro and Leonora, homonym protagonists of the opera by Giuseppe Verdi, based on her devotion by them, because of this, it becomes a passionate and original reporting. The narrative of Piñon is built from a parodist and irreverent place that updates the plot of Verdi. This is a metanarrative in which the narrator dialogues with her characters and reader. In this case, the reference to the opera by Verdi is, actually, the exploration of artistic and cultural archives in accordance with the interests of the narrator. Methodologically, this paper is guided by the exploitation of intertextuality present in this work and in gender studies to enhance the speaking place of the writer as a real part of contemporary feminist culture.
