1. IPR 102 - Dwarf Arabica coffee cultivar with resistance to bacterial halo blight
Abstract ‘IPR 102’ is a coffee cultivar derivative from a cross between “Catuaí” and “Icatu”. ‘IPR 102’ is a dwarf cultivar (medium size) with high rusticity, late ripening cycle, and it is resistant to bacterial halo blight and partial resistant to coffee leaf rust.

2. IPR 100 - Rustic dwarf Arabica coffee cultivar with resistance to nematodes Meloidogyne paranaensis and M. incognita
Abstract ‘IPR 100’ was derived from a crossing between “Catuaí” and a hybrid (“Catuaí” x BA-10 coffee). ‘IPR 100’ is a medium size dwarf cultivar with high rusticity, with late ripening cycle, and with resistance to Meloidogyne paranaensis and to some M. incognita populations.

3. Physiological and ultrastructural analysis reveal the absence of a defined abscission zone in coffee fruits
ABSTRACT In order to investigate the existence of a possible abscission zone in the binding region between the peduncle and the coffee fruit, as well as the biochemical events involved in fruit ripening, we studied peduncles and fruits of Coffea arabica L. cv. “Icatu amarelo”. Coffee fruits were harvested at different maturation stages by using specific

4. Caracterização in silico e análise da expressão de genes das rotas de biossíntese e sinalização do etileno em frutos de diferentes cultivares de café (coffea arabica) / In silico characterization and expression analysis of genes of the ethylene biosynthesis and signaling pathways in fruits of different coffee (Coffea arabica) cultivars
Coffee is the second most commercialized product in the world posing as an important source of income and jobs in several countries, mainly in developing countries such as Brazil, the largest producer and the second largest consumer of coffee in the world. Coffee quality, among other factors, is directly associated to the fruit ripening stage at harvest time

5. Produção de cafeeiros enxertados em área isenta de nematóides / Produção de cafeeiros enxertados em área isenta de nematóides / Production of grafted coffee cultivars on nematode free area / Production of grafted coffee cultivars on nematode free area
This work had the objective to evaluate the effect of grafting and Apoatã IAC 2258 cultivar as rootstock on ripening uniformity, yield and physical quality of beans of seven Coffea arabica cultivars. The experiment was conducted on an area free of nematodes located at the Agronomy Department of Lavras Federal University, Lavras, MG, Brazil, in January 2004.

6. Caracterização bioquímica e molecular da ß-Galactosidade durante a maturação de frutos de coffea arabica
ß-galactosidases are a class of glycosyl-hydrolases that act on the plant cell primary walls, hydrolyzing ß-D-galactose at the nonreducing ends of ß-D-galactosides present in several biological molecules. Initially a characterization of the monosaccharides present in the primary wall of the pericarp and endosperm of Coffea arabica fruits at different ripe

7. Expression patterns of three a-expansin isoforms in Coffea arabica during fruit development.
As a first step towards understanding the physiological role and regulation of the expansin gene (EXP) family in Coffea arabica fruits during growth and maturation, we identified 11 expansin genes, nine belonging to the expansin family (EXPA), one EXLA and one EXLB, through in silico analysis of expressed sequence tags (ESTs). Within the expansin family, thr

9. Caffeine degradation in leaves and fruits of coffea arabica and coffea dewevrei.
The coffee species Coffea dewevrei and Coffea arabica have marked differences in caffeine metabolism and the control of the caffeine content during fruit ripening and leaf aging is still not clear. The aim of this work was a detailed investigation on the alkaloid degradation in young and aged leaves, and immature and mature fruits of these species. Young and

10. Sucrose metabolism during fruit development in coffea racemosa.
Sucrose is one of the compounds in the raw coffee bean that has been identified as an important precursor of coffee flavour and aroma. In order to increase our knowledge of sucrose metabolism in coffee species, sucrose and reducing sugar content were investigated in the fast fruit-ripening coffee species Coffea racemosa. Fruits were harvested regularly from

12. Physiological and biochemical characteristics of two coffee cultivars of early and late ripening stages / CaracterÃsticas FisiolÃgicas e BioquÃmicas de Frutos de Duas Cultivares de Cafà de Ciclos de MaturaÃÃo Precoce e Tardio
The asynchronous ripening of coffee fruits plays an important role on coffee production and it leads to higher costs, harvest difficulties and to a low quality beverage. This study aimed at to assess two coffee cultivars with distinct fruit ripening patterns: Catucaà 785-15, which shows an early fruit ripening process and AcauÃ, which is known by its late
