“…The production observed in this study of 3.0 cuttings per stump and week was consistent with results found in the literature: 5.6 cuttings per stump every 5-10 days in a clonal nursery, in sand bed (Wendling et al, 2003); 2.4 cuttings per stump every 7 days in a clonal nursery, in tubes with subirrigation (Titon et al, 2003); 8.1 every 25 to 30 days in a clonal nursery in sand and 4.1 in a system of clonal mini tubes (without subirrigation) (Cunha et al, 2005). By extrapolating the NMC/MS of this experiment to annual production, a production of 14,364 cuttings m -2 yr -1 is estimated.…”

“…On the other hand, the adoption of a minicuttings management and collection methodology which aimed to preserve mini-stumps over successive collects also proved to be fundamental and is in accordance with different studies for different Eucalyptus species (MORI DA CUNHA et al, 2005;CUNHA et al, 2005). According to Ferriani et al (2010), the excessive removal of sprouts in mini-stumps growing in a mini-garden system can induce its higher mortality, mainly due to phytotoxic effects of high nutrients concentrations.…”

“…In this context, mini-cuttings technique can be classified as an evolution of the cutting process, since it tends to reduce the area required for mother plants conduction by adopting clonal minigarden, reducing also the rooting and acclimatization period and, above all, making unnecessary in some cases the application of plant growth regulators to induce rooting FERRIANI et al, 2010).…”

-We aimed to evaluate the technical efficiency of mini-cuttings technique on vegetative propagation of Paulownia fortunei (Seem.) Hemsl. var. Mikado, as well as the possible existence of anatomical barriers to its rooting. Therefore, plants originated from cuttings formed the mini-stumps and, consequently the clonal mini-garden, which was conducted in semi-hydroponic system. We evaluated the survival of mini-stumps and sprouts production for five successive collects, the percentage of mini-cuttings rooting and their anatomical description. The mini-cuttings were prepared with about 6 to 8 cm in length and two leaves reduced by about 50% in the upper third, being remained an area of, approximately 78 cm² (10 cm diameter). The mini-cuttings were placed in tubes of 53 cm³, with substrate formed with fine vermiculite and carbonized rice hulls (1:1 v/v) and rooted in acclimatized greenhouse. After 30 days we evaluated the percentage of rooted mini-cuttings, radicial vigor (number and length of roots / mini-cutting), callus formation, emission of new shoots and maintenance of the original leaves. The mini-stumps showed 100% survival after five collects and an average production of 76-114 mini-cuttings/m²/month and rooting ranged from 70 to 90%. Mini-cuttings technique is efficient in to propagate adult propagules of the species and there are not anatomical barriers preventing roots emission.Keywords: Rejuvenation; Mini-stumps; Anatomy.

“…A produção média mensal avaliada por esses autores foi de 9,7 miniestacas por minicepa. Em Eucalyptus benthamii, Cunha et al (2005) verificaram menor produção de miniestacas pelas minicepas, na primeira coleta de brotação. Os autores relataram que a produção de miniestacas aumentou após as sucessivas coletas.…”

ResumoO uso da miniestaquia para a multiplicação de cultivares de goiabeira pode permitir o estabelecimento de novos protocolos para a obtenção de mudas produzidas em condições de controle ambiental. Este trabalho foi realizado com o objetivo de avaliar a técnica de miniestaquia para multiplicação de cultivares de goiabeira. Foram instalados três experimentos em delineamento de blocos casualizados, utilizando-se quatro cultivares (Paluma, Pedro Sato, Cortibel 1 e Cortibel 6) e quatro repetições. Foram avaliados a emissão de brotações das minicepas após sucessivas coletas, a capacidade de enraizamento das miniestacas em diferentes épocas e o crescimento das mudas. As minicepas tiveram capacidade de emissão de brotações dos 49 aos 397 dias após o desponte, permitindo sete coletas de brotações. A maior porcentagem de enraizamento das miniestacas foi verificada em dezembro. Nessa época, constatou-se que as cultivares Paluma, Pedro Sato, Cortibel 1 e Cortibel 6 tiveram médias de 92%, 75%, 75% e 79% de enraizamento respectivamente. Entretanto o percentual de enraizamento das miniestacas da 'Cortibel 1' foi mais influenciado pelas épocas, sendo registrados 16,7% e 45,8% em novembro e em junho respectivamente. Aos 138 dias após o estaqueamento, as alturas das mudas estavam dentro dos padrões técnicos recomendados para o plantio no campo, entre 45 e 50 cm. Com base nesses resultados, conclui-se que a miniestaquia é viável para a multiplicação dessas cultivares.Palavras-chave: Psidium guajava, minicepas, propagação, mudas. Multiplying guava cultivars by minicutting technique AbstractThe use of the minicutting technique for multiplying guava tree cultivars might allow the establishment of new protocols to obtain plantlets grown under better environmental control. This study was carried out to evaluate the minicutting technique for multiplying guava tree cultivars. Three experiments were carried out in randomized block design, using four cultivars (Paluma, Pedro Sato, Cortibel 1 and Cortibel 6) and four replicates. In these experiments, the lateral shoot emission of ministumps after successive harvests, the rooting capacity of cuttings in different seasons and the growth of plantlets were evaluated. The highest percentage of cutting rooting was observed in December. By that time, the average rooting of cultivars Paluma, Pedro Sato, Cortibel 1 and Cortibel 6 was 92%, 75%, 75% and 79%, respectively. However, the rooting percentage of 'Cortibel 1' minicuttings was most influenced by the month of the year, ranging from 16.7% and in November to 45.8% in June. After 138 days from cutting establishment, the plantlet heights were within the recommended technical standards for transplanting to the field, between 45 and 50 cm. Based on these results, it was concluded that the minicutting technique is feasible for multiplying these cultivars.
