“…These punctuated decreases in the growth rate of some genotypes may be associated with a severe attack of Hemileia vastatrix that occurred in some clones, high maximum air temperatures (above 34ºC, with some days exceeding 38°C), and the water deficit observed in January and February ( Figure 1AB). It must be noted that decreases in the growth rate values varied according to the genotype studied, as C. canephora responds differently to soil water deficit (DaMatta et al, 2003;Praxedes et al, 2006).…”

Knowledge about the seasonality of different genotypes of Coffea canephora is an important tool for this crop management, particularly with regard to irrigation and fertilisation issues. This study was conducted in Espírito Santo, Brazil and aimed at to evaluate the seasonal vegetative growth in genotypes of C. canephora, as related to climatic factors, based on the growth of groups of orthotropic and plagiotropic branches with different ages. Three groups of plagiotropic branches and one group of orthotropic branches of 14 genotypes (Ipiranga and 13 that belonged to the variety Vitória) were selected and marked to followed along the one-year experiment. Three-year-old plants were cultivated under full-sun conditions, with a spacing of 3 m between rows and 1 m between plants. The growth rates of the orthotropic and plagiotropic branches differed among the genotypes and underwent seasonal variation during the entire year, with high correlations to the air temperature. Under the natural experimental conditions, the growth rate of the branches decreased when the minimum air temperatures were below 17.2ºC for most of the genotypes studied. The plagiotropic branches presented lower vegetative growth, mainly for the coffee berries, compared to the younger branches. Presumably, the genotypes of C. canephora demanded more nutrients for growth between mid-September and the second week of May.

“…In both arabica and robusta coffee grown in the field, OA is not a general trait observed in genotypes grown under rainfed conditions (Meinzer et al, 1990b;DaMatta et al, 2003). In genotypes showing some OA, its magnitude generally is smaller than 0.3 MPa under full turgor, and seldom larger than 0.5 MPa.…”

“…There is a considerable genetic variation in ∆ in both arabica and robusta coffee (Meinzer et al, 1990a;DaMatta et al, 2000DaMatta et al, , 2003. Working with five genotypes of arabica, Meinzer et al (1990a) pointed out that a higher long-term WUE (lower ∆) under adequate irrigation resulted from decreased g s rather than increased A at a given g s .…”

This paper briefly reviews some selected traits (leaf area, crown architecture, water-use efficiency and carbon isotope discrimination, water relations and root characteristics), which may be explored in breeding programmes to tolerance to drought stress in arabica and robusta coffee.Key words: Coffea, water deficit, water use, yield.Explorando a tolerância à seca em café: uma abordagem fisiológica com algumas contribuições para o melhoramento vegetal: Nesta revisão, analisam-se brevemente algumas características (área foliar, arquitetura da copa, eficiência do uso da água e discriminação isotópica do carbono, relações hídricas e características radiculares) que podem ser exploradas em programas de melhoramento para tolerância à seca em cafeeiros arábica e robusta. Palavras-chave:Coffea, déficit hídrico, produção, uso da água.

“…The significant correlation between A and g s , as found for arabica coffee, but not for conilon, might be associated with the better coupling of g s with the atmospheric evaporative demand in the former.

After oil, coffee is the most valuable traded commodity worldwide. In this review we highlighted some aspects of coffee growth and development in addition to focusing our attention on recent advances on the (eco)physiology of production in both Coffea arabica and C. canephora, which together account for 99% of the world coffee bean production. This review is organized into sections dealing with (i) climatic factors and environmental requirements, (ii) root and shoot growth, (iii) blossoming synchronisation, fruiting and cup quality, (iv) competition between vegetative and reproductive growth and branch die-back, (v) photosynthesis and crop yield, (vi) physiological components of crop yield, (vii) shading and agroforestry systems, and (viii) high-density plantings. Key words: arabica, conilon and robusta coffee, beverage quality, density planting, die-back, flowering, photosynthesis, shading Ecofisiologia do crescimento e da produção do cafeeiro: O cafeeiro, depois do petróleo, é a principal mercadoria comercializada no mundo. Nesta revisão, analisam-se aspectos do crescimento e desenvolvimento do cafeeiro, dandose, também, ênfase aos avanços recentes sobre a (eco)fisiologia da produção de Coffea arabica e C. canephora, que respondem por cerca de 99% da produção mundial de café. Abordam-se (i) os fatores climáticos e requerimentos ambientes, (ii) crescimento da parte aérea e das raízes, (iii) sincronização da floração, frutificação e qualidade da bebida, (iv) competição entre os crescimentos vegetativo e reprodutivo e ocorrência de seca de ramos; (v) fotossíntese e produção, (vi) componentes fisiológicos da produção, (vii) sombreamento e sistemas agroflorestais, e (viii) plantios adensados. Palavras-chave: cafeeiros arábica, conilon e robusta, fotossíntese, floração, qualidade de bebida, seca de ramos, sombreamento
