Resumo: | The Eucalyptus is the genus that has the highest number of researchs in micropropagation. However, there are few effective results obtained with their continuous proliferation. Micropropagation includes disinfection and culture of explants in nutrient medium and aseptic conditions, multiplication in successive subcultures and in vitro or ex vitro rooting. As advantages, the micropropagation allows: high yield per donor plant, freevirus plants, production of saplings at any time of the year, intensive production of healthy saplings in a short period of time and in a limited space, cloning of plants difficult-to-propagate by conventional methods, such as cutting and minicutting, and donor plant preservation without risk of infection. Its disadvantages include the dependence on a tissue culture laboratory, which results in high maintenance costs, as well as the requirement of highly trained workers, high possibility of contamination, variation of conditions within and among clones, the difficulty of finding appropriate culture medium for the species desired and possibility of mutation as a result of the use of growth regulators. Despite having high cost when compared to other cloning methods, the species and hybrids of eucalypt micropropagation is strategic to maintain superior plant material in vitro or to supply the micro-clonal hedge. doi: 10.4336/2009.pfb.58.49 |

A micropropagação inclui a desinfestação e cultivo dos explantes em meio nutritivo e condições assépticas, a multiplicação dos propágulos em sucessivos subcultivos e o enraizamento in vitro ou ex vitro. Como vantagens, possibilita: alto rendimento por planta matriz; obtenção de plantas isentas de viroses; produção de mudas em qualquer época do ano; produção intensiva de mudas sadias, em curto período de tempo e espaço reduzido; clonagem de plantas de difícil propagação vegetativa por métodos convencionais como estaquia e miniestaquia; e preservação de plantas matrizes sem riscos de infecção. Suas desvantagens incluem a dependência de um laboratório de cultura de tecidos, cuja manutenção implica em altos custos, além da exigência de mão-de-obra altamente especializada; elevada possibilidade de contaminação; variação de condições entre e dentro de clones; dificuldade de encontrar o meio adequado para a espécie desejada; e possibilidade de ocorrência de mutações, como resultado do uso de fitorreguladores. Embora tenha alto custo em comparação a outros métodos de clonagem, a micropropagação de eucalipto é estratégica para manter material vegetal superior in vitro ou para abastecer o microjardim clonal.
