ABSTRACT This work evaluated the initial performance and genetic diversity of Coffea canephora genotypes cultivated in environments at contrasting altitudes. Fourteen morphophysiological traits and seven descriptors of the genus Coffea spp. of coffee trees cultivated at altitudes of 140 m and 700 m were evaluated. The design used was Federer’s augmented block in a 2 × 112 factorial scheme with six blocks. The first factor was the two environments, and the second was the 112 genotypes, with eight common treatments, being five conilon coffee clones and three arabica coffee cultivars. The data were analyzed by the method of REML/BLUP and genetic correlation method. Genetic diversity was evaluated by estimating the distance matrix, applying the Gower methodology followed by the clustering method by Tocher and UPGMA. The phenotypic means were higher in the environment at an altitude of 700 m, except for plant height, number of leaves, and canopy height (CH). Genotypic effects were significant for most traits except for leaf width, CH, unit leaf area, and total leaf area. A wide genetic diversity was verified, with distances varying from 0.037 to 0.593 for the pairs of genotypes 26 × 93 and T7 × 76, respectively. Most of the traits studied showed high genotypic correlation with the environment and expressive genetic correlation between the evaluated traits thereby demonstrating the possibility of indirect selection. There is an adaptation of conilon coffee genotypes to high altitudes and the possibility of developing a specific cultivar for the southern state of Espírito Santo. spp 14 70 Federers Federer s 11 blocks treatments cultivars REMLBLUP REML BLUP matrix UPGMA leaves CH.

Abstract The objective of this work was to evaluate the morphophysiological responses and cutting production of clones of Conilon coffee (Coffea canephora) cultivars in a super-dense clonal garden in the state of Espírito Santo, Brazil. The super-dense clonal garden was built in 2019 using 39 clones: 9, 9, 9, and 12 of cultivars Centenária ES8132, Diamante ES8112, ES8122 (Jequitibá), and Marilândia ES8143, respectively. The experiment was carried out in a randomized complete block design, with three replicates. Cutting production and the following morphophysiological traits were evaluated at 9 and 18 months after planting: chlorophyll index, normalized difference vegetation index, plant height, canopy height, canopy diameter, number of shoots, number of viable cuttings, number of leaves, fresh leaf mass, and plant fresh and dry matter mass. The super-dense clonal garden caused different morphophysiological responses among the studied clones. In general, clones C2, C5, C6, C8, D1, D8, D9, J8, M2, M9, M10, and M12 showed a higher mean cutting production, whereas C4, J1, J4, M4, and M5 were the most sensitive to the super-dense regime. Under these conditions, it is recommended to increase the proportion of matrix plants of the latter clones.

Resumo O objetivo deste trabalho foi avaliar as respostas morfofisiológicas e a produção de estacas de clones de cultivares de café conilon (Coffea canephora) em jardim clonal superadensado, no estado do Espírito Santo, Brasil. O jardim clonal superadensado foi implantado em 2019, com 39 clones: 9, 9, 9 e 12 das cultivares Centenária ES8132, Diamante ES8112, ES8122 (Jequitibá) e Marilândia ES8143, respectivamente. O experimento foi realizado em delineamento em blocos ao acaso, com três repetições. A produção de estacas e as seguintes características morfofisiológicas foram avaliadas aos 9 e 18 meses após o plantio: índice de clorofila, índice de vegetação por diferença normalizada, altura da planta, altura da copa, diâmetro da copa, número de brotações, número de estacas viáveis, número de folhas, massa fresca de folhas, e massa fresca e seca da planta. O jardim clonal superadensado promoveu diferentes respostas morfofisiológicas entre os clones estudados. Em geral, os clones C2, C5, C6, C8, D1, D8, D9, J8, M2, M9, M10 e M12 apresentaram maior produção média de estacas, enquanto C4, J1, J4, M4 e M5 foram os mais sensíveis ao regime superdenso. Nessas condições, recomenda-se aumentar a proporção de plantas matrizes destes clones.

Resumo: O objetivo deste trabalho foi avaliar o efeito da velocidade de uma colheitadeira de café e sua interação com clones de café 'Conilon' (Coffea canephora) sobre a eficiência da colheita mecanizada. O experimento foi instalado em São Mateus, no Espírito Santo, em 2012, com 27 clones com frutos de maturação precoce, intermediária e tardia. A primeira colheita foi feita após o corte das plantas a 0,5 m acima do solo, em 2016, e a renovação da copa. As plantas e a colheitadeira foram avaliadas em 2018. A colheitadeira foi testada às velocidades de 0,6 e 0,8 km h-1. As mensurações foram feitas quanto à eficiência de derriça e colheita, à perda dos frutos no chão, aos frutos não derriçados, à desfolha com as colheitas manual e mecanizada, à força de desprendimento e ao grau de maturação dos frutos. Os testes com a colheitadeira de café indicaram viabilidade técnica com eficiência de 88% de colheita média e desfolha 15% menor do que a da colheita manual. A velocidade de colheita de 0,8 km h-1 resulta em maiores eficiências de derriçados e de colheita, em menores perdas no chão e em menos frutos não derriçados, independentemente dos clones avaliados. A força de desprendimento e o grau de maturação influenciam a eficiência de descascamento e de colheita e a percentagem de frutos não descascados de café 'Conilon'.

Abstract: The objective of this work was to evaluate the speed effect of a coffee harvester and its interaction with 'Conilon' coffee (Coffea canephora) clones on the mechanical harvesting efficiency. The experiment was installed in São Mateus, in the state of Espírito Santo, Brazil, in 2012, with 27 clones of early, intermediate, and late fruit ripening. The first harvest was performed after the plant cuttings at 0.5 m above the ground, in 2016, and the canopy renovation. The plants and the harvester were evaluated in 2018. The coffee harvester was tested at 0.6 and 0.8 km h-1. Measurements were performed for stripping and harvesting efficiencies, fruit loss on the ground, unstripped fruit, defoliation with manual and mechanized harvesting, fruit removal force, and fruit ripening degree. The tests with the coffee harvester indicated a technical feasibility of 88% average harvesting efficiency, and a 15% lower defoliation than the manual harvesting. The harvesting speed of 0.8 km h-1 results in higher stripping and harvesting efficiencies, in a lower percentage of loss on the ground, and in less unstripped fruit, regardless of the evaluated clones. Fruit removal force and ripening degree influence the stripping and harvesting efficiencies and the percentage of unstripped fruit of 'Conilon' coffee.
