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.
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'.

Papaya meleira virus (PMeV) is the causal agent of papaya sticky disease. This study describes two methods for molecular diagnosis of PMeV using conventional and real-time PCR. These methods were shown to be more efficient than current methods of viral detection using extraction of PMeV dsRNA and observation of symptoms in the field. The methods described here were used to evaluate the effect of inoculation of papaya plants with purified PMeV dsRNA on the progress of PMeV infection. A single inoculation with PMeV dsRNA was observed to delay the progress of the virus infection by several weeks. The possibility of vertical transmission of PMeV was also investigated. No evidence was found for PMeV transmission through seeds collected from diseased fruit. The implications of these results for the epidemiology of PMeV and the management of papaya sticky disease are discussed. |
