Pruning management of mini-stumps for mass propagation of blueberry

The objective of this work was to evaluate the influence of the pruning management of mini-stumps of the Climax blueberry cultivar, when weekly fertigated, on the productivity of the clonal mini-garden and on the rooting and root vigor of the mini-cuttings. The high survival of the mini-stumps (100%...

Zusammenfassung:The objective of this work was to evaluate the influence of the pruning management of mini-stumps of the Climax blueberry cultivar, when weekly fertigated, on the productivity of the clonal mini-garden and on the rooting and root vigor of the mini-cuttings. The high survival of the mini-stumps (100%) and production of the mini-cuttings (182.9 mini-cuttings per square meter per month) evidence the high adaptability of the material to successive samplings and to the nutritional conditions provided to the clonal mini-garden, resulting in a high multiplication rate. The rooting percentages obtained at the different samplings remain stable, with a high average of rooted mini-cuttings, reaching 81.7%. Resumo: O objetivo deste trabalho foi avaliar a influência do manejo de poda de minicepas da cultivar Climax de mirtilo, quando fertirrigadas semanalmente, sobre a produtividade do minijardim clonal e sobre o enraizamento e o vigor radicial das miniestacas. As elevadas sobrevivência das minicepas (100%) e produção de miniestacas (182,9 miniestacas por metro quadrado por mês) evidenciam a boa adaptação do material às coletas sucessivas e às condições nutricionais fornecidas ao minijardim clonal, o que resultou em alta taxa de multiplicação. Os percentuais de enraizamento obtidos nas diferentes coletas se mantêm estáveis, com média elevada de miniestacas enraizadas, que alcança 81,7%.
