| Abstract Apple production has been an important economic activity worldwide. The wide dissemination and cultivation of apple trees in several regions of the world is due to the development of propagation techniques from its domestication to the present time. Apple trees can be propagated by seeds, restricted to the use in breeding programs, and multiplied by several methods of vegetative propagation, both for rootstocks and apple scion cultivars. Considering the high technological level currently used in apple crop management, plant propagation plays a very important role in order to enable seedling production with high morphological quality and free of diseases, requiring new advances and propagation improvements in new releases of rootstocks and apple... |

| 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 The propagation of many passion fruit species (Passiflora spp.) is done by seeds or sexual method, although asexual propagation, such stem cuttings, grafting or tissue culture is also possible and very useful in many cases. In this work, it was presented information on scientific and technological advances in sexual and asexual propagation of passion fruit, considering the different propagation methods and their applications. New demands for research and development activities are also related, given the wide range of passion fruit species and its potential for food, ornamental and medicinal use. |

| 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 Grapevine production by classical grafting methods and in commercial scale emerged over 130 years. This system remained handmade until the mid-1950s, when the first international certification programs aimed at obtaining mother plants with high viral sanity emerged. The necessity to increase the scale of production on industrial model and plant material production based on minimum morphological standards appeared at the end of the 1960s. Along the 1970s, research unlocked knowledge on semi-automated grafting, process hygiene, use of plant growth regulators and understanding of physiological events of rootstock-scion compatibility, callus formation and rooting. So, until the mid-2000s, certification schemes and propagation processes advanced... |

| 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 In this study were evaluated gas exchanges, fruit production and fruit quality of tomato Santa Cruz Kada grafted onto different species of the genus Solanum, using two grafting methods. For the grafted tomato cultivation, the authors used a randomized complete block design, in a 8x2 factorial scheme, evaluating eight rootstocks: accessions of mini tomatos (0224-5, RVTC 57, RVTC 20 and 6889-50); wild tomato species Solanum habrochaites var. hirsutum (PI-127826); Solanum pennellii (LA716); Solanum sessiliflorum (cubiu); and tomato cultivar Santa Cruz Kada (self-grafting, control), and two grafting methods {cleft grafting (FC) and approach grafting (EC)}. The authors verified a significant interaction between rootstock x grafting method. The S.... |

| Objetivou-se avaliar a indução de brotações epicórmicas em cepas e as técnicas de estaquia, miniestaquia e enxertia para a clonagem de Cupressus lusitanica. Para a estaquia, testaram-se concentrações de ácido indolbutirico e substratos em plantas de 5 e 10 anos de idade. Na miniestaquia, avaliou-se o tipo de propágulo. Na enxertia, utilizaram-se propágulos de árvores de 10 anos como enxertos para o primeiro subcultivo, sendo, a partir deste, coletadas as brotações para o segundo subcultivo. A espécie apresentou difícil enraizamento e a enxertia, o melhor resultado. A indução de brotações de cepas apresentou baixa viabilidade.doi: 10.4336/2010.pfb.30.62.161 |

| RESUMO: Este trabalho foi conduzido no viveiro da Embrapa Cerrados, em Planaltina (DF), com o objetivo de avaliar a viabilidade da enxertia de mudas de mangabeira (Hancornia spp.) pelos métodos de garfagem lateral à inglesa simples, borbulhia de placa com janela aberta e borbulhia de escudo com lenho. A realização da enxertia ocorreu durante a estação chuvosa de verão. Os porta-enxertos apresentavam diâmetro do caule entre 0,5 e 1 cm a 10 cm do solo e foram produzidos em sacos plásticos de 20 x 30 cm. Para a obtenção dos enxertos, foram utilizadas quatro plantas-matriz em bom estado vegetativo, com folhas maduras nas últimas brotações e sem frutos. O delineamento experimental foi de blocos ao acaso, com três tratamentos (três métodos de enxertia) e oito... |

| ABSTRACT Passion fruit wilt, caused by Fusarium spp., is one of the most severe diseases for this crop. Although yellow passion fruit is propagated mostly by seeds, the use of rootstocks tolerant to early death could be a management strategy for cultivation in areas with disease history. Thus, this study characterized Fusarium isolates obtained in Triângulo Mineiro and determined the most suitable genotype to use for grafting to reduce losses caused by this pathogen. Mycelial growth and sporulation of Fusarium isolates, in three different growth media, was quantified by measuring colony diameter and by counting the conidia in Neubauer chamber 10 days after growth in malt extract-agar 2%, PDA or CMA at 22 ± 3ºC and 12 hours lighting. Five days later the... |

| The etiolation and layering technique that is used on avocados has two critical steps, namely, the rooting of clonal rootstock and graft union formation between the commercial variety and clonal rootstock. This study analyzed the rooting step of the clonal rootstock regarding its influence on graft union formation and development. The optimum times for grafting the commercial variety onto clonal avocado rootstock were determined under two greenhouse conditions, heating and no heating. The results showed that under greenhouse conditions without heating, there was higher survival (%) in plants that were grafted 60 days after the rooting steps in the clonal scion, and, in the experiments in a heated greenhouse, the highest survival rate (%) was observed in... |

| Abstract The vegetative propagation in cacao has been used in Central America since the beginning of the last century. However, only from the end of the century this technique has been intensified in the state of Bahia, where vegetative propagation changes have increased the yield of cocoa growing areas, especially those using other technologies associated with clonal seedlings. The use of clonal garden to collect stems in nursery can reduce by 80% the space required for maintenance of stock plants. On the other hand, the buds obtained from orthotropic and plagiotropic shoots are used to improve the performance protocols and reduce production costs of seedlings. Among the current and future challenges in the production of cocoa seedlings emphasizes the... |
