“…However, 30% recovery was obtained in plants rewatered to 25% soil water saturation after forty-eight hours. Drought directly and indirectly impacts photosynthesis, which is one of the primary metabolic processes influencing plant growth and development (Pieters & El Souki, 2005;Praxedes et al, 2006). Miyashita et al (2005) reported similar recovery process to the present study in kidney beans (Phaseolus vulgaris) after forty-eight hours of re-watering in plants grown under drought stress.…”

This greenhouse study was carried out to determine the impact of drought on plant growth, photosynthetic rate and the recovery of photosynthesis after drought relief. Twenty four Roselle plants were equally divided between the control and the treatment groups, which received 100% and 25% soil saturation respectively. The plants were grown under greenhouse conditions with the temperature averaging 27 ± 2ºC. The treatments were applied with seven cycles of watering until the plants reached the anthesis stage. The drought influence caused a significant reduction in the plant height, flower number, and photosynthetic rate. Re-watering the plants growing under drought to 100% water saturation resulted in complete recovery of photosynthetic rate within forty-eight hours. However, rewatering to 25% showed only 30% recovery in photosynthetic rate after forty-eight hours. Photosynthetic pigments including chlorophyll a, b and carotenoid were not significantly influenced by the drought. Similarly, total phenolic compound concentration of the calyx was insignificant between the treatments. However, Anthocyanin concentration of the calyx was significantly higher under the drought treatment.

“…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).…”

“…In coffee, low temperatures (below the range of 13-17 ºC, depending on the authors and genotypes) and pronounced water deficit (-3 MPa) affect various components of the photosynthetic process, as it reduces the stomatal conductance, net photosynthesis, photochemical efficiency of photosystem II, thylakoid electron transport, enzyme activity and carbon metabolism as a whole. Low temperatures also affect the composition and structure of photosynthetic pigment complexes and of the lipid matrix of cell membranes, particularly in the chloroplast, although to different extent among genotype and species Ramalho et al, 2003;Silva et al, 2004, Praxedes et al, 2006Partelli et al, 2009Partelli et al, , 2011Batista-Santos et al, 2011). Such changes may reflect impairments or damages, but in some cases are responses towards plant cold acclimation.…”

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.

“…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.
