ABSTRACT Brazil is the largest Coffea arabica L. producer and exporter in the world market. In view of the need for nitrogen fertilization, the objective of this work was to evaluate the use of digital images of coffee leaves as a function of nitrogen concentration and cultivars, as well as to evaluate the most adequate sampling of this technique to predict leaf nitrogen. The experiment was set in a greenhouse, at UNESP - Experimental Campus of Registro-SP, using 12L pots with medium sand. A completely randomized design was adopted, in a 4 x 2 factorial scheme, with four concentrations of N (0, 50, 100 and 200 mg dm-3), and two coffee cultivars (Mundo Novo and Obatã), with ten replications. The variables evaluated were: hue, dark green color index (DGCI), leaf area and leaf nitrogen content. The hue and DGCI were influenced by N concentration, cultivar and are dependent on the day after treatment application and the number of leaves used. The use of five leaves per replication was more adequate to estimate leaf N content. Hue, DGCI and leaf area were higher in Obatã depending on the day after application of the treatment and N concentration.

RESUMEN En los últimos años el cultivo de café guatemalteco ha sufrido declinación en su rendimiento como resultado de la roya del café. El uso de cultivares resistentes a esta enfermedad y con potencial para producir cafés con buena calidad de bebida es fundamental para la sustentabilidad del cultivo en el país. El objetivo de este estudio fue analizar el potencial de calidad del grano y el perfil sensorial de genotipos de café Arábica resistentes a la roya, en función de diferentes tiempos de fermentación biológica. El experimento se implementó en julio de 2014, en la finca El Panorama, ubicada en el municipio de San Rafael Pie de La Cuesta, Departamento de San Marcos, Guatemala. Se probaron ocho progenies F5 resistentes a la roya y se utilizaron como controles los cultivares Marsellesa y Bourbon Amarelo. Cada genotipo fue sometido a dos tiempos de fermentación biológica en agua, después del pelado (24 y 72 h). El diseño experimental fue bloques completos al azar con tres repeticiones en un esquema factorial 10 (genotipos) × 2 (tiempos), totalizando 60 unidades experimentales. Se evaluó la calidad, perfil sensorial y granulometría de los tratamientos. Todos los genotipos estudiados resistentes a la roya mostraron potencial para la producción de cafés especiales en Guatemala y una granulometría superior en relación al Bourbon Amarelo. Marsellesa y Bourbon Amarelo obtuvieron puntajes finales más altos y los atributos de sabor, regusto, acidez, cuerpo, equilibrio y en general, fueron más acentuados. El tiempo de fermentación biológica no influyó en la puntuación final del café (pontuación total en el protocolo SCA); sin embargo, hubo un cambio en el perfil sensorial, con énfasis en el cultivar Marsellesa, que aumentó la frecuencia de notas frutales y redujo las notas de caramelo con mayor tiempo de fermentación.

SUMMARY In recent years, the Guatemalan coffee plantations have suffered a decline in its yield as a result of coffee rust. The use of cultivars resistant to this disease and with the potential to produce coffee with good drinking quality is essential for the sustainability of coffee cultivation in the country. The aim of this study was to analyze bean quality potential and the sensory profile of rust-resistant Arabica coffee genotypes as a function of different times of biological fermentation. The experiment was carried out in July 2014, at El Panorama farm, located in the municipality of San Rafael Pie de La Cuesta, Department of San Marcos, Guatemala. Eight rust resistant F5 progenies were tested and cultivars Marsellesa and Bourbon Amarelo were used as controls. Each genotype was subjected to two times of biological fermentation in water, after peeling (24 and 72 h). The experimental design was randomized complete blocks with three replications, in a 10 (genotypes) × 2 (times) factorial scheme, totaling 60 experimental units. The quality, sensory profile and granulometry of the treatments were evaluated. All the rust-resistant genotypes studied showed potential to produce specialty coffees in Guatemala and a superior granulometry in relation to Bourbon Amarelo. Marsellesa and Bourbon Amarelo obtained higher final scores and the attributes flavor, aftertaste, acidity, body, balance and overall were more accentuated. The time of biological fermentation did not influence the final score of the coffee (total score in the SCA protocol); however, there was a change in the sensory profile, with emphasis on cultivar Marsellesa, which increased the frequency of fruity notes and reduced caramel notes with longer fermentation time.

Resumo O objetivo deste trabalho foi selecionar genótipos de Coffea arabica com boa produtividade e potencial de tolerância ao deficit hídrico, além de tentar compreender os mecanismos fisiológicos e anatômicos envolvidos na adaptabilidade desses genótipos ao estresse hídrico. Avaliaramse características fisiológicas, anatômicas e agronômicas de 19 genótipos de C. arabica sob as duas seguintes condições hídricas: irrigação regular e sem irrigação (deficit hídrico no solo). Os genótipos 'IPR 100', 2, 5 e 7 apresentaram características agronômicas, fisiológicas e anatômicas que contribuíram para melhor manutenção do estado hídrico no desenvolvimento inicial do cafeeiro. Com base nesses resultados, esses genótipos são potencialmente tolerantes ao deficit hídrico. Os genótipos 4, 10, 11, 14, 15 e 'Bourbon Amarelo IAC J10' apresentam menor adaptabilidade das estruturas anatômicas em condições de deficit hídrico no solo. Os genótipos de cafeeiro apresentam plasticidade foliar, como a espessura do parênquima paliçádico e esponjoso, e o número, posição, dimensões e mobilidade dos estômatos em condições de deficiência hídrica.

Abstract The objective of this work was to select genotypes of Coffea arabica with good yield and potential tolerance to water deficit, as well as to try to understand the physiological and anatomical mechanisms involved in the adaptability of these genotypes to water stress. The physiological, anatomical, and agronomic traits of 19 genotypes of C. arabica were evaluated under the two following water conditions: regular irrigation and no irrigation (soil water deficit). The 'IPR 100', 2, 5, and 7 genotypes showed agronomic, physiological, and anatomical traits that contributed to a better water status maintenance in the initial development of coffee plants. Based on these results, these genotypes are potentially tolerant to water deficit. The 4, 10, 11, 14, 15, and 'Bourbon Amarelo IAC J10' genotypes show a lower adaptability of the anatomical structures under soil-water deficit conditions. The coffee tree genotypes display leaf plasticity, such as the thickness of palisade and spongy parenchyma, and the number, position, dimensions, and mobility of stomata under water deficit conditions.

RESUMO A produção de mudas de clone de Coffea arabica L. é uma das alternativas de maior demanda para cafeicultores, existindo programas de melhoramento através da técnica de embriogênese somática, no entanto, os clones apresentam dificuldades de pegamento na fase de aclimatação em casa de vegetação elevando custo de produção. Uma alternativa testada com resultados promissores é a inoculação com fungos micorrízicos arbusculares (FMA) durante o processo de aclimatação das mudas. Assim, o objetivo deste trabalho foi promover a melhoria do processo de produção de mudas através de embriogênese somática associada a inoculação com fungos micorrízicos arbusculares. Para a produção dos clones, plântulas foram utilizadas quando apresentaram quatro pares de folhas (clone 1 “Frutificação vermelha Catucaí” e clone 2 “Acauã”) produzidos e desenvolvidos em biorreatores “embriogênese somática” e quando levadas para o viveiro inoculadas com Rhizophagus clarus, Gigaspora margarita e Acaulospora mellea, a mistura de R. clarus e G. margarita e a mistura de R. clarus, G. margarita e A. mellea. Após seis meses foram avaliados os parâmetros agronômicos, teores de nutrientes foliar e a colonização micorrizica nas raízes. Os clones se comportaram diferentemente quando inoculados com o FMAs, sendo que o clone 1, o que apresentou melhor desenvolvimento no viveiro determinadas pelos parâmetros agronômicos, sendo indicada na produção de mudas clonais vigorosas qu, ando associado a inoculação com fungos micorrízicos arbusculares.

ABSTRACT The production of Coffea arabica L. clone seedlings through the somatic embryogenesis technique is one of the alternatives of greatest demand for coffee producers. However, clones can face difficulties related to acclimatization carried out under greenhouse conditions, which can increase the production costs. A tested alternative with promising results is inoculation with arbuscular mycorrhizal fungi (AMF) during the seedling acclimatization process. Thus, this study aimed to promote the improvement of the seedling production process through somatic embryogenesis associated with inoculation with AMF. For the production of the clones, seedlings were used in the phase when they presented four pairs of leaves (Clone 1 “Fruiting red Catucaí” and Clone 2 “Acauã”), using “somatic embryogenesis” bioreactors, followed by inoculation with Rhizophagus clarus, Gigaspora margarita and Acaulospora mellea, a mixture of R. clarus and G. margarita and a mixture of R. clarus, G. margarita and A. mellea. After six months, agronomic parameters, leaf nutrient contents and root mycorrhizal colonization were evaluated. The studied clones behaved differently when inoculated with AMFs. Clone 1 showed the best development in the greenhouse, which was determined by the agronomic parameters. Thus, Clone 1 is indicated for the production of vigorous seedlings when associated with inoculation with AMFs.

Abstract In the northern Minas region, the dry-warm climate predisposes coffee plants to the occurrence of leaf miners, mites, cercosporiosis, and leaf scald. Aiming for the development of a cultivar adapted to these conditions, Coffea canephora Pierre ex A. Froehner clones were selected through genetic parameters under an irrigated system, without agrochemicals. Eighteen agronomic traits were evaluated. The survival rate, number of nodes per plagiotropic branch, leaf miner infestation and cercosporiosis incidence were chosen as characteristics for selection of ‘Vitória Incaper 8142’, once they have shown superiority of the genetic parameters. The survival rate variable was used to rank the EMCAPA 8141 Robustão Capixaba clones. Clones V2, V4, V6, V13, RC7, and RC9 were selected as more tolerant to pests and diseases and can provide genetic improvements in conilon breeding program for region. The genetic dissimilarity identified between clones allowed suitable clone combinations to be proposed for use in future crosses.

As respostas à disponibilidade dos nutrientes variam entre espécies distintas dentro de um mesmo gênero, por causa, principalmente, das exigências nutricionais variáveis, capacidade de absorção, translocação e utilização dos nutrientes. O objetivo deste trabalho foi avaliar a eficiência de absorção, translocação e uso dos micronutrientes por diferentes cultivares de Coffea arabica L., enxertados em Apoatã IAC 2258 (Coffea canephora). O experimento foi instalado em casa de vegetação, utilizando-se o método de cultivo em solução nutritiva. Foi utilizado um fatorial 7 x 3 + 2, sendo sete cultivares de Coffea arabica L. (Palma II, Catucaí 2 SL, Oeiras MG 6851, Obatã IAC 1669-20, Acauã, Topázio MG 1190 e Paraíso MG H 419-1), três tipos de mudas (pé franco, autoenxertada e enxertada sobre o cultivar Apoatã IAC 2258) e duas testemunhas (Apoatã autoenxertado e Apoatã pé franco). O porta-enxerto utilizado influenciou negativamente na absorção de boro, ferro e manganês. A translocação dos micronutrientes boro e cobre obteve maiores índices nas mudas enxertadas. O cultivar Palma II, quando enxertado, apresentou o maior índice de utilização dos nutrientes, mostrando-se passível de ser enxertado. O porta-enxerto utilizado mostrou-se apto para a enxertia, por não sofrer influência negativa, tanto pela enxertia, quanto pelos cultivares utilizados.

Responses to availability of nutrients vary between different species within the same genus, mainly because the different nutritional requirements, absorption capacity, translocation and use of nutrients, The purpose of this study was to evaluate the efficiency of absorption, translocation and use of micronutrients by different cultivars of Coffea arabica L. grafted into Apoatã IAC 2258 (Coffea canephora). The experiment was conducted in a greenhouse using cultivation in nutrient solution in a 7 x 3 + 2 factorial design: seven cultivars of Coffea arabica L. (Palma II, Catucaí 2 SL, Oeiras MG 6851, Obatã IAC 1669-20, Acauã, Topázio MG 1190 and Paraíso MG H 419-1), three types of seedlings (ungrafted, self-grafted and grafted on cultivar Apoatã IAC 2258) and two controls (Apoatã self-grafted and Apoatã foot-free). The results showed that the rootstocknegatively influenced the absorption of boron, iron and manganese. The translocation of the micronutrients boron and copper had the highest rates in the grafted seedlings. The cultivar Palma II, when grafted, showed the highest rates of use of nutrients, showing that it can be grafted. The rootstock proved to be suitable for grafting, for not being negatively influenced by both the grafting and the cultivars used.

The experiments were installed and carried out in the counties of Três Pontas, Campos Altos and Capelinha, Minas Gerais state, Brazil. The experiments were carried out in a randomized complete block design, with four replicates and six plants per plot. The treatments were constituted by 15 cultivars of the Catuaí group and five controls. The grain yield evaluations were performed in the six harvests from 2003/2004 to 2008/2009 growing seasons. Then, the joint analysis of the three localities and the evaluation of cultivars adaptability and stability were performed. The parameters floating beans and high sieve grains were carried out considering the 2008/2009 harvest. The cultivars Catuaí Vermelho IAC 15, Catuaí Amarelo IAC 30, Catuaí Amarelo IAC 62 and Catuaí Vermelho IAC 72 were the most promising because they allied higher stability and adaptability in favorable and unfavorable environments with mean high yield. The cultivars Catuaí Vermelho IAC 100, Catuaí Amarelo IAC 86, Rubi MG 1192 and Catuaí Vermelho IAC 144 have the highest percentage of bean size grains. All the cultivars showed low percentage of floating grains

O objetivo deste trabalho foi avaliar características de crescimento de cafeeiros nos estágios iniciais de desenvolvimento e determinar suas correlações com a primeira produtividade de lavouras cultivadas em diferentes ambientes. Foram avaliadas 22 cultivares resistentes à ferrugem, e três testemunhas suscetíveis, em cinco locais representativos do cultivo de cafeeiro no Estado de Minas Gerais. Os experimentos foram realizados de 2005 a 2008, em blocos ao acaso, com três repetições. Além da produtividade inicial dos cultivos, foram avaliadas cinco características de crescimento, aos 12 meses do plantio: diâmetro de caule, número e comprimento dos ramos plagiotrópicos, altura de plantas e número de nós. Estimaram-se as correlações genotípicas e fenotípicas entre todas as características avaliadas. As cultivares Pau Brasil MG1 e Catuaí Amarelo IAC 62 foram superiores em pelo menos quatro das cinco características avaliadas, em todos locais de cultivo. Há correlação positiva entre a produtividade inicial do cafeeiro e as características de crescimento avaliadas, com exceção do número de nós.

The objective of this work was to evaluate coffee growth traits in the initial stages of development and to determine its correlation with the crop initial yield in different environments. Twenty-two cultivars resistant to rust and three susceptible ones were evaluated in five representative coffee growing localities in the state of Minas Gerais, Brazil. The experiment was carried out from 2005 to 2008 in a randomized complete block design with three replicates. Besides initial yield, five growth traits were evaluated 12 months after planting: stem diameter, number and length of plagiotropic branches, plant height, and number of nodes. The genotypic and phenotypic correlations were evaluated for all traits. Pau Brasil MG1 and Catuaí Amarelo IAC 62 cultivars show superiority in at least four out of the five evaluated characters, in all growing localities. There is a positive correlation between initial yield and the evaluated growth traits, except number of nodes.

Conduziu-se este trabalho com o objetivo de avaliar progênies de cafeeiro resultantes do cruzamento entre 'Icatu' x 'Catimor', quanto à produtividade e vigor vegetativo e selecionar progênies superiores para avançar no programa de melhoramento dessa população. O delineamento utilizado foi em blocos casualizados com quatro repetições, 30 tratamentos (29 progênies do cruzamento mais a cultivar Rubi MG 1192, utilizada como testemunha). Para análise de variância dos dados adotou-se o esquema de parcela subdividida no tempo. Foram analisados a produção em sacas beneficiadas.ha-1 de seis colheitas 2001/2002 a 2006/2007 e o vigor vegetativo avaliado após a colheita 2006/2007. Os resultados obtidos permitem verificar a presença da variabilidade genética para produção entre as progênies avaliadas, fato confirmado pela alta estimativa da maioria das progênies estudadas, demonstraram que é possível selecionar progênies superiores na população estudada.

The objective of this research was to evaluate coffee progenies resulted from the crossing of 'Icatu' with 'Catimor' in relation to their production and plant vigor and to select higher quality progenies to advance the breeding program of this population. For this purpose, a randomized complete block design was carried out with four replications and for the analysis of variance, the Split plot temporal arrangement was adopted. Twenty nine progenies plus the Rubi MG 1192 cultivar, used as a control, were evaluated. The yield of beans in bags.ha-1 of six harvests from 2001/2002 to 2006/2007 was evaluated and the plant vigor after the harvest was assessed. The results indicated that the evaluated progenies showed variability mainly for grain yield confirmed by heritability. This condition associated to high bean yields, which reached 62.0 bags.ha-1 and high plant vigor, showed the possibility of selecting outstanding progenies in the studied population.
