| 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 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,... |

| 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... |

| 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... |

| In this study, the canola stalk cutting parameters including modulus of mass density of stalk, special work of useful cutting, coefficient of cutting useful work and crush resistance coefficient were examined. For the tests, testing machine Instron (Model Santam STM-5) with 50 N load cell was used. Cutting was performed with a saw-serrated cutting blade that was attached to the Instron movable jaw. Stems were cut at three diameter levels (1 to 3, 3 to 5 and more than 5 mm), three cutting speed levels (75, 115 and 150 mm/minute), three cutting angles (0°, 30° and 60°) and three replicates. Cutting parameters including modulus of mass density of stalk, special work of useful cutting, coefficient of cutting useful work and crush resistance coefficient... |

| 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. |

| Com a finalidade de reduzir o tamanho do saco de plastico para a formacao de mudas de seringueira, tornando esta tecnica viavel para os heveicultores, foi conduzido, no CNPSD, um experimento onde foram testados sacos de plastico de coloracao preta, sanfonados lateralmente, com 0,16mm de espessura. Como substrato foi utilizado solo da camada aravel de Latossolo Amarelo muito argiloso. A adubacao do substrato consistiu de incorporacao de superfosfato triplo, cloreto de potassio e calcariodolomitico. A adubacao nitrogenada feita por meio de regas quinzenais com ureia, sendo duas apos o amadurecimento do primeiro lancamento foliar do enxerto e duas, apos o segundo lancamento. |

| 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... |
