1. Irrigation and Light Access Effects on Coffea arabica L. Leaves by FTIR-Chemometric Analysis
Coffee bean chemical compositions has been extensively studied. However, there is a small amount of research on other parts of the coffee plant, including leaves. Fourier transform infrared (FTIR) spectral profiles of Coffea arabica L. cv. IAPAR 59 leaf extracts from a simplex-centroid design were studied by principal component analysis (PCA) to evaluate the

2. Aquaporins and the control of the water status in coffee plants
Six aquaporin (AQP) homologues were identified in three coffee species (Coffea arabica, C. Canephora, and C. racemosa), including four plasma membrane intrinsic proteins (PIP1;1, PIP1;2, PIP2;1, and PIP2;2) and two tonoplast intrinsic proteins (TIP1;1 and TIP1;2). In order to better understand the role of these genes in coffee, C. arabica cvs Catuaí and Mun

3. Coffee leaf analysis using DRIS from irrigated and non-irrigated plantations in the alto Paranaíba region / Diagnose foliar em cafeeiro de sequeiro e irrigado na região do alto Paranaíba com o uso do DRIS
Cerrado soils have low fertility and under-dosing of fertilizers leads to nutritional imbalance on coffee plantations. This study aimed to: comparatively characterize the main deficiencies, nutritional imbalances and excesses in the aerial part of coffee plant; indicate nutrients which respond well to fertilization and their synergistic and antagonistic inte

4. Identificação e caracterização de genes candidatos para a tolerância à seca em cafeeiro / Identification and characterization of candidate genes for drought tolerance in coffee
Coffee is economically important and widely cultivated in Brazil. The cultivated area is well distributed throughout the territory, whereby C. arabica and C. canephora are produced, depending on the region. Usually, drought and adverse temperatures are the major weather constraints to coffee production. The importance of such limitations should increase, acc

5. MANEJO DA IRRIGAÃÃO NA LAVOURA CAFEEIRA (Coffea arabica L.) RECEPADA / Of pruned coffee trees under different irrigation management strategies.
The experiment was carried out in Lavras-MG with objective to evaluate different irrigation management strategies and their effect upon flowering induction, flower boom and grain production on pruned coffee, and their effect to increase productivity, save water and energy on irrigation. The study was conducted at the experimental area of Engineering Departme

6. Lâminas de irrigação por gotejamento na cultura do cafeeiro / Drip irrigation depths in the coffees culture
The purpose of the present work was to evaluate the vegetative development, productivity, yield and income from Rubis coffee, inbred MG-1192, cultivated under different irrigation depths during the period of 2002 to 2008. The experiment was carried out at the Glórias experimental farm, situated at 1858 South latitude and 4812 West longitude, and an altitude

7. Paralisação da irrigação e sincronia do desenvolvimento das gemas reprodutivas de cafeeiros orgânico e adensado
The experiment was carried out at Água Limpa Farm, Brasília University. It aimed to evaluate irrigation paralyzation effect on syncronism of the development of reproductive buds of two coffee tree cultivars raised in a high density organic system, and after cutting primary lateral branches and coffee tree top. It was used IAPAR 59 and Obatã cultivars with

8. Estudo de alguns eventos do florescimento do cafeeiro relacionados a fatores do ambiente / Study of some coffee tree flowering events related to environmental factors.
The coffee tree flowering involves several events related with the factors of plant and environmental characteristics. A better comprehension on the flowering events and the relations among those factors can improve the knowledge in cropping practices, mainly in irrigation techniques, aiming to promote the homogeneity on the flowering and, consequently, on t
