| A pimenta-do-reino (Piper nigrum L.) vem sendo cultivada no Estado do Acre desde a década de 80. A não expansão da cultura deve-se, principalmente, à carência de material genético, à baixa produção de mudas, bem como ao número reduzido de informações técnico-científicas dessa piperacea nas condições edafoclimáticas do estado. Assim, foi conduzido um experimento, em fevereiro de 1992, onde foram testados quatro métodos de enraizamento, visando oferecer alternativas no uso de substratos para o enraizamento de estacas herbáceas de pimenta-do-reino. |

| No processo de desenvolvimento de mudas de guarana por estacas, um dosfatores fundamentais e' a manutencao da umidade, desde o enraizamento a transferencia da planta ao campo. Varios metodos de irrigacao foram testados para enraizamento de estacas de guarana, onde analisaram-se alguns sistemas de nebulizacao, apresentados neste trabalho em forma de projeto, com um viveiro de 10000 mudas de guarana enraizadas por estacas, com as dimensoes, componentes necessarios e o esquema montado, alem de caracterizar o usuario para sua adocao, recomendavel para a regiao amazonica. |

| O objetivo deste estudo foi avaliar o desenvolvimento inicial de Myrsine guianensis Aubl. (azeitona-do-mato) e Diospyros sericea A. DC. (olho-de-boi), função de duas doses de fósforo e da inoculação com fungos micorrízicos arbusculares (FMA) nativos do Cerrado. Ambas as espécies são lenhosas nativas de Matas de Galeria do Distrito Federal e apresentam potencial de utilização em plantios mistos destinados ao repovoamento de áreas degradadas. As mudas foram produzidas, em viveiro, irrigado, com 30% de sombreamento, em tubetes de 290 ml. O inoculante de fungos micorrízicos arbusculares constitui em uma mistura das espécies Glomus brasilianum, Glomus etunicatum, Gigaspora margarita e Scutellospora cerradensis. Como tratamentos, foram utilizados duas... |

| Afin d’évaluer le potentiel de régénération de Gracilaria verrucosa du lac de Bizerte, une culture expérimentale, in situ sur cordes tendues sur le substrat, a été mise en place à partir de boutures de 200 g. Au terme de quatre mois de culture, de février à mai 2003, les cordes ont été soumises à une, deux, trois ou quatre coupes. L’analyse statistique montre que la meilleure situation est représentée par les touffes qui n’ont subi qu’une seule coupe à la fin du mois de mai; dans ce cas, ces touffes ont un poids final de 1771,4 g et un taux de croissance spécifique de 1,8. |

| Christ's thorn (Ziziphus spina-christi (L.) Desf.) is a cross-pollinated plant with a wide range of genetic variability in nature and, for this reason, vegetative propagation assumes importance for improvement programs. The objective of this work was to evaluate cutting, T budding and tissue culture methods for this species. Shoots of 22-25 cm length were treated by two culture media and three shoot diameters for cutting trial. The T budding treatments consisted of three and five collection dates in spring and autumn, respectively. Tissue culture nodal segments bearing axillary buds were removed from shoots of mature trees at different seasons. Experiments to determine the best disinfectant chemical, appropriate conditions and materials to prevent phenolic... |

| Abstract The Myrtaceae family has representatives spread worldwide, and Jabuticaba tree is an important species native to Brazil, which is grown not only in the backyards and domestic orchards, but also in commercial orchards, landscaping projects and in several tropical and subtropical countries. The propagation of this species in a sexual form or by seeds is simple and efficient, being able to reach 100%. However, long juvenile phase and genetic segregation have led to the search for methods that allow the propagation of selected trees and guarantee through their standardized and productive clones, fruit quality and fruiting precocity. Protocols for asexual propagation are still scarce, but they show efficient methods, making possible the commercial use... |

| ABSTRACT Guava (Psidium guajava L.) can be propagated by seed, layering, air layering, grafting (budding or grafting), cuttings (root or shoot) or tissue culture. Propagation by seed is used for rootstock production and for raising populations for screening at early phases in the breeding programs. Vegetative propagation methods are used to clone selected genotypes from these programs and commercial orchards because it perpetuates all characteristics of each cultivar. This review addresses different methods that can be used to propagate guava, the methods commercially adopted and the progress obtained in recent years. There are several propagation technologies available, however, the adoption levels are rather different between producing countries. Needs... |

| Abstract This review aims to present advances in studies on the propagation of the Annonaceae species, which includes species of economic importance such as: soursop, custard apple, atemoya and cherimoya. In sexual propagation, advances are mainly related to a better understanding of the stages of seed development, dormancy mechanisms, and germination. In asexual propagation, compatibility studies between grafts and rootstocks are presented, focusing on the expression of genes involved in tissue formation. The cutting method is also discussed, which is another option for the propagation for this group of plants considered difficult to root, approaching endogenous and exogenous factors related to the subject, as well as management strategies that affect... |

| ABSTRACT Nursery trees of stone fruits (Prunus spp.) are traditionally produced by union of two distinct genotypes - the rootstock and the scion - which, by grafting, form a composite plant that will be maintained throughout of all plant life. In Brazil, the rootstocks are predominantly seed propagated and therefore usually results in heterogeneous trees for vigor and edaphic adaptation. However, with advances in rootstock breeding programs that released cultivars and certification in several countries (notably in Europe), the system will come gradually evolving for vegetative propagation (cuttings and tissue culture) and use of seeds of selected rootstocks with specific characteristics and potted nursery trees production. For scion cultivar propagation,... |
