“…These differences in crop yield are rather unlikely to result from differences in photosynthetic performance as evaluated in single leaves (see Figure 3). In general, however, compared to arabica, conilon seems to be less responsive to atmospheric evaporative demand -with better response to irrigation (DaMatta and Ramalho, 2006) and, in addition, its more open architecture might result in higher light transmittance through the canopy. Taken together, these traits would favour maintenance of gas exchange capacity for longer periods, and overall total carbon assimilation would be greater in conilon than in arabica, which would, perhaps, partly explain the superior performance of the high-yielding progenies of conilon as compared with their arabica counterparts.…”

“…Relatively high temperature during blossoming, especially if associated with a prolonged dry season, may cause abortion of flowers (Camargo, 1985). It should be noted, however, that selected cultivars under intensive management conditions have allowed arabica coffee plantations to be spread to marginal regions with average temperatures as high as 24-25ºC, with satisfactory yields, as in northeastern Brazil (DaMatta and Ramalho, 2006). On the other hand, in regions with a mean annual temperature below 17-18ºC, growth is largely depressed.…”

“…In these zones, provided that the agroforestry system is correctly managed [proper choice of shade tree species (often deeply rooted species), judicious evaluation of planting density, frequency of canopy pruning and tree thinning, soil type, water and thermal regimens], water-use efficiency is expected to rise, turning the use of shade trees in agroforestry systems a highly recommended option. This should be translated into obvious advantages to the production of coffee plantations in dry and hot environments (DaMatta, 2004a;DaMatta and Ramalho, 2006), provided that shading is not excessive. Nevertheless, it should be emphasized that under optimal or near-optimal edaphoclimatic conditions for coffee cultivation, such as those of the highlands (600-900 m above sea level) of southeastern Brazil, shading provides little, if any, benefit to the crop; in most cases it is even detrimental (Camargo, 1990;Campanha et al, 2004;Morais et al, 2006).…”

“…Several aspects of coffee (eco)physiology have recently been reviewed, including water relations and drought tolerance (Carr, 2001;Rena, 2001, 2002a;DaMatta, 2004c;DaMatta and Ramalho, 2006), photosynthetic acclimation to light availability (DaMatta, 2004a), nitrogen metabolism (Carelli et al, 2006), seed physiology (Eira et al, 2006), caffeine (Baumann, 2006), and impacts of extreme temperatures and drought on coffee physiology and production (DaMatta and Ramalho, 2006). Therefore, these aspects will not be examined here in detail.…”

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

“…Such mechanisms and traits included stress avoidance behavior as observed in coffee, and other woody species, via stomatal control of water loss during a dry period coupled with high atmospheric vapor-pressure deficits, and deep-rooting (Hernández et al, 1989;DaMatta and Ramalho, 2006); differential timing between female-ear silking and male-tassel pollen grain shedding in maize (Bolaños and Edmeads, 1993a,b;Bolaños et. al, 1993); and some osmotic adjustment and morphological and anatomical changes that affects leaf water loss such as cuticle waxing, leaf hairs and rolling, and root hydraulicresistance such as observed in cereals (Richards and Passioura, 1981a,b;Morgan, 1984;Passioura, 1988;Blum et al, 1989;Blum and Pnuel, 1990;Blum, 1993).…”

Utilidade da pesquisa básica em fisiologia vegetal e em fisiologia da produção em relação ao melhoramento das culturas: uma revisão e uma análise pessoal: A pesquisa e o desenvolvimento agrícola têm função essencial no desenvolvimento econômico das nações, provendo segurança alimentar para uma população em constante crescimento demográfico. Em países desenvolvidos, as lacunas entre a produção potencial e a produção real são sobremodo estreitas, devido a uma combinação de tecnologias avançadas, novas variedades altamente produtivas e aplicação de agroquímicos em sistemas de produção altamente mecanizados. Na maioria daqueles países, a produção agrícola supera a demanda nacional, resultando em excedentes para a exportação. Em muitos países em desenvolvimento, entretanto, a produtividade agrícola está ainda muito abaixo de seu potencial devido a limitações técnicas e sócio-econômicas. Déficit alimentar é a norma em países pobres e subdesenvolvidos, os quais requerem vultosas importações de alimentos. Para aliviar parcialmente essa situação, pesquisas de cunho agrícola devem ser reforçadas. Como ramos das ciências básicas, a fisiologia vegetal e a fisiologia da produção têm sido freqüentemente criticadas por não traduzirem seus resultados de pesquisa em melhoria da produtividade. Este artigo é focado nesse tema, apresentando uma avaliação das realizações pretéritas da pesquisa fisiológica e de seus impactos sobre o melhoramento das culturas e sobre a produção de alimentos. Discutem-se deficiências e limitações de pesquisas isoladas e de pouca relevância, juntamente com opiniões do cientista sobre como pesquisas efetivas na área da fisiologia devem ser conduzidas e integradas dentro de equipes de pesquisa multidisciplinares associadas ao melhoramento vegetal. Exemplos de pesquisas de sucesso na fisiologia da produção e suas contribuições para aumentar a produtividade agrícola são apresentados. Todos esses aspectos apontam para a necessidade de pronto financiamento da pesquisa básica por setores públicos e privados de países desenvolvidos. Palavras-chave: agricultura, ecofisiologia, ecossistemas, estresse hídrico, fotoperíodo, fotossíntese C 4 , hormônios, melhoramento, produtividade, solo, tolerância à seca Agricultural research and development plays an essential role in a nation s economic development, providing for food security for an ever-increasing population. In developed countries, the gap between potential and actual yield is largely closed because of a combination of advanced technologies, high-yielding new varieties and the application of agrochemicals in highly mechanized production systems. In most of these countries, agricultural production exceeds national demand, resulting in excess products for export. In many of the developing countries, however, agricultural productivity is still far below what it should be because of multiple technical and socio-economic constraints. Food deficits are the norm in poor and middle-income countries, requiring expensive food imports. To partially alleviate this situati...

Coffee is one of the world's most valuable export commodities and about 125 millions people depend on coffee for their live hood. The recent development of large coffee expressed sequence tag (EST) as well as the development of coffee bacterial artificial chromosome (BAC) libraries is leading to an enormous production of information in the area of coffee genomics. To take advantage of these resources, a key issue is the development and use of methods like genetic transformation to define gene functions at the molecular and organism level. The present chapter first describes the actual breeding and genomics strategies for the two cultivated species Coffea arabica and C. canephora . In a second part, all the methods and gene constructs used to develop transgenic coffees since the first work in 1991 are precisely analyzed. These methods include electroporation, biolistic delivery and Agrobacterium tumefaciens and A. rhizogenes ‐mediated transformation. Results of transgene expression for herbicide resistance, pathogen resistance and physiological traits are also presented. In the following part, the expected products of coffee transgenics are discussed. They deal with resistance to insect pests and nematodes, decaffeinated coffee, resistance to abiotic stresses, pathogen resistance, and improvement in cup quality characteristics and fruit ripening. Finally, the actual bottlenecks of coffee genetic transformation and the ongoing technology developments are described.
