MERGING TWO QFD MODELS INTO ONE: AN APPROACH OF APPLICATION

This paper presents an approach to the application of Quality Function Deployment that brings together the models developed by Don Clausing (Enhanced QFD) and Akao. In this way, the proposed approach benefits from focusing, at the same time, at: parameter extraction, systematizing the decision taking process within its matrices (Enhanced QFD); and the identification of relationships among different parameters of the product development process (QFD by Akao). The steps involved in the proposed approach are depicted and justified. Finally, a discussion is made on the effect of QFD on development cycle time and the benefits of the proposed approach

Resposta de porta-enxertos de citros ao déficit hídrico Response of citrus rootstocks to water deficit

O trabalho foi conduzido em casa de vegetação na Embrapa Mandioca e Fruticultura, em Cruz das Almas - BA, e objetivou-se à identificação de porta-enxertos de citros melhor adaptados ao ecossistema de Tabuleiros Costeiros, quanto a tolerância à seca. Foram estudados os limoeiros 'Cravo' e 'Volkameriano', laranjeira 'Azeda' e os híbridos trifoliados HTR - 051, TSK x CTTR - 002 e TSK x CTTR - 017. O delineamento experimental foi o inteiramente casualizado, em esquema fatorial 6 õ 9, com seis genótipos e nove tempos de avaliação. As avaliações foram realizadas na sequência: irrigação, déficit hídrico e irrigação, quando plantas possuíam de 3 a 4 pares de folhas. Foram analisadas as variáveis massas secas da raiz e da parte aérea, o potencial hídrico da planta e a transpiração da folha. Quanto à massa seca da parte aérea, os genótipos limoeiro Volkameriano e laranjeira 'Azeda' apresentaram decréscimos no período de déficit hídrico, sendo que os demais não apresentaram diferenças significativas. Na ausência de irrigação, todos os genótipos apresentaram decréscimos nos seus potenciais hídricos, enquanto apenas os híbridos apresentaram recuperação, mantendo a transpiração. Os híbridos HTR - 051 e TSK x CTTR - 017 apresentaram os melhores desempenhos para todas as variáveis estudadas, mostrando-se mais promissores como porta-enxertos de citros em condições de déficit hídrico.<br>This work was carried out under green house condition at the Embrapa Cassava and Tropical Fruit Crops, Cruz das Almas - Bahia- Brazil, aiming to identify citrus rootstocks better adapted to Coastal Table Land ecosystem as for their drought tolerance. It was studied the Rangpur lime, Volkamer lemon, Sour orange and the trifoliated hybrids HTR - 051, TSK x CTTR - 002, and TSK x CTTR - 017, the last three from the breeding program of the Embrapa Cassava and Tropical Fruits Crops. The experimental design was completely randomized under a 6 x 9 factorial, with six genotypes and nine period of evaluations. The evaluations followed the sequence: irrigation, water deficit, and irrigation when the plants had two to three leaves pairs. It was analyzed the variables root dry matter, dry matter of above ground parts, plant water potential, and leaf transpiration. For the above ground dry matter the genotypes Volkamer lemon and Sour orange showed decrease during the water deficit condition. The other genotypes showed no significant differences for this variable. Without irrigation, all genotypes decreased in their water potentials. The hybrids kept it unchanged maintaining increased transpiration rates. The hybrids HTR - 051, and TSK x CTTR - 017 presented the best performances for all variables studied being more promising as rootstocks for water deficit conditions

Growing knowledge: an overview of Seed Plant diversity in Brazil

Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora
