Zusammenfassung: | Abstract The objective was to evaluate different methods of propagation and initial development of the lychee according to the place of production. The propagation methods were the Forking in seedlings produced in São João de Petrópolis-Santa Teresa and Air Layering in São João de Petrópolis, Santa Teresa-HQ, Colatina and Santa Maria de Jetibá. Each treatment consisted of 50 plants, and the percentage of graft catch, grape pick and transplant to the field was evaluated after three months. The seedlings produced in the different propagation sites were planted in the production field, with a spacing of 5x5 meters, being used as each treatment, 10 seedlings propagated in different places by Air Layering and propagation by forking. The propagation by Air Layering showed a better rate of catch than in grafting by Forking, however the Forking maintained 100% maintenance of the seedlings alive after the harvest. The treatments represented by the Air Layering in Colatina and São João showed the best results, showing that the spreading by Air Layering presents superior results when we use for the propagation, plants produced in places with similar characteristics to the planting site. Propagation by Air Layering is the best method of propagating lychee seedlings. Alporques propagated in the same region where the seedlings produced are definitively planted have greater adaptability and better development in the production field.
Resumo Objetivou-se avaliar diferentes métodos de propagação e de desenvolvimento inicial da lichieira em função do local de produção. Os métodos de propagação foram a garfagem em mudas produzidas em São João de Petrópolis-Santa Teresa, e alporquia em São João de Petrópolis, Santa Teresa-sede, Colatina e Santa Maria de Jetibá. Cada tratamento foi composto de 50 plantas, sendo avaliadas a porcentagem de a pega na enxertia,a pega na repicagem e no transplantio para o campo, após três meses. As mudas produzidas nos diferentes locais de propagação foram plantadas no campo de produção, com um espaçamento de 5x5 metros, sendo utilizadas em cada tratamento, 10 mudas propagadas nos diferentes locais por alporquia e a propagação por garfagem. A propagação por alporquia apresentou melhor índice de pega que na enxertia por garfagem, porém a garfagem manteve 100% de manutenção das mudas vivas após a repicagem. Os tratamentos representados pela alporquia, em Colatina e São João, apresentaram os melhores resultados, mostrando que a propagação por alporqui |
