Asexual propagation of peach palm by division of the clump and extraction of the off-shoots
Provedor de dados: Horticultura Brasileira
Autores: Flores,Wanders BC; Yuyama,Kaoru; Silva,Raimundo G da.
The peach palm (Bactris gasipaes) is a native Amazonian palm tree that produces fruits and palm hearts, and is now attracting the interest of the farmers in other parts of Brazil given the economical potential of palm heart production. Traditionally the peach palm is propagated by seeds, which yield segregating progenies due to cross-pollination. To guarantee the uniformity and quality of elite selections, the alternative is the propagation of superior genotypes from off-shoots (tillers), because an efficient in vitro cultivation protocol does not exist. The objective of the present study was the development of a more appropriate technique of vegetative propagation by division of the clump, in order to multiply plants selected in the improvement program. A...

Autores: Marodin,Josué C; Resende,Francisco V; Resende,Juliano TV de; Gabriel,André; Zeist,André R; Constantino,Leonel V; Sanzovo,Alisson WS.
ABSTRACT Studies on the interaction between garlic plant density and virus-free seed size are scarce in Brazil. Thus, this study was installed to evaluate the effect of plant spacing and seed size on garlic traits and yield for infected and virus-free bulbs. Treatments were arranged in a randomized block design and 2x5x3 factorial combination [infected and virus-free bulbs, five plant spacings (210, 260, 300, 360, and 390 cm2 per plant), and three bulbous seed sizes (sieve one, two, and three)]. The highest bulb yield was observed for virus-free seeds at a plant spacing of 390 cm2 plant-1, while the highest commercial yield was verified for 210 cm2 plant-1 spacing. The combination of virus-free seeds, larger bulbs, and 332 cm2 plant-1 spacing promoted the...

Produção de mudas de cafeeiros por sementes e estacas.
Provedor de dados: Informação Tecnológica em Agricultura (Infoteca-e)
Autores: BERGO, C. L.; SÁ, C. P. de; SALES, F. de.
A propagação do cafeeiro é feita de duas formas: sexuada, que se baseia no uso de sementes, e assexuada, baseada no uso de estruturas vegetativas das plantas, a exemplo do uso das estacas, ou pedaços de seus ramos. No Acre, o processo usual de propagação do cafeeiro, tanto da espécie arabica como canephora, é por semente. Embora a Embrapa já tenha difundido a produção vegetativa por meio de estaca para o café Conilon, da espécie canephora, ainda são poucos os produtores que utilizam esta técnica. Este trabalho trata destas duas formas de produção de mudas de café.

Propagação vegetativa do mogno (Swietenia macrophylla King) por enraizamento de estacas semilenhosas em câmara úmida.
Provedor de dados: Informação Tecnológica em Agricultura (Infoteca-e)
Autores: MIRANDA, E. M. de; MIRANDA, K. R. de.
A exploração predatória do mogno representa uma ameaça à sobrevivência da espécie, provocando a destruição da maior parte do germoplasma, especialmente daquelas árvores com as características mais desejáveis para a produção de madeira, às quais representam alto potencial de conservação "in situ" como plantas matrizes. Diante desta realidade e dada a importância da espécie para a produção de madeira de alto valor, são necessários estudos com o objetivo de desenvolver um método prático de reprodução vegetativa para estabelecer uma estratégia de conservação e reprodução do germoplasma de melhor qualidade. Entre os métodos de propagação vegetativa recomendados a espécies tropicais para produção de madeira, destaca-se o enraizamento de estacas semilenhosas em...

Adição de condicionadores orgânicos e inorgânicos em substrato comercial para o cultivo em vasos de Melocactus violaceus subsp. violaceus.
Provedor de dados: Informação Tecnológica em Agricultura (Infoteca-e)
Autores: CORREIA, D.; TANIGUCHI, C. A. K.; BERNARDO, J. C.; MATOS, M. de C.
A espécie Melocactus violaceus é endêmica das regiões Nordeste e Sudeste do Brasil, habita ambientes florestais ou campestres, como Mata Atlântica e Restinga, e ocorre geralmente sobre substratos arenosos e dunas litorâneas. A vulnerabilidade dessa espécie deve-se à forte pressão antrópica, que modifica e fragmenta os habitats, e ao extrativismo constante. A reprodução dessa espécie ocorre via sementes. Poucos estudos existem sobre propagação e formas de cultivos. Este trabalho teve como objetivo avaliar a combinação de substrato comercial com misturas de condicionadores orgânicos e inorgânicos para o cultivo em vasos de M. violaceus subsp. violaceus.

Influência do Ferbam e do anelamento da haste clonal na enxertia da seringueira (Hevea spp.) na microrregião Alto Purus, AC.
Provedor de dados: Informação Tecnológica em Agricultura (Infoteca-e)
Autores: LINS, A. C. R.; CASTRO, F. de A.
A propagação da seringueira é geralmente feita por enxertia sendo mais empregado o método Forkert (tipo convencional) que consiste na inclusão da gema em "seedlings", porta enxertos de um ano de idade. Por este meio de propagação obtém-se seringais com uniformidade no desenvolvimento e na produção, diferindo portanto dos seringais nativos. Outras vantagens favorecidas pela técnica, seria a multiplicação vegetativa fácil, garantia do alto rendimento e resistência às enfermidades de interesse econômico. É recomendável, ainda, a utilização dos métodos borbulha de catáfilo, com a parte superior do escudo embutido, e borbulha da folha com a parte inferior do escudo embutido, ambos com fita plástica transparente, na prática da enxertia verde.

Provedor de dados: PFB - Pesquisa Florestal Brasileira
Autores: de Lima, Daniela Macedo; Klein, Anderson Wiliam; Salla, Vanessa Padilha; Cardoso Moura, Amanda Pacheco; Danner, Moeses Andrigo.
The objective of this work was to evaluate the effect of indolebutyric acid (IBA) on rooting of Langerstroemia indica cuttings in different substrates. Semi-hardwood cuttings with 7-8 cm were treated in alcoholic solutions of IBA (0, 1,000, 2,000 and 3,000 mg L-1) for 10 s and staked in plastic tubes containing commercial organic substrate or vermiculite. A completely randomized design in factorial arrangement 4 x 2 (4 concentrations x 2 substrates) was used. After 75 days we evaluated percentages of rooted cuttings, with shoots and necrosis, number and length of roots and number of shoots per cutting. IBA in concentration 1,000 mg L-1 promoted best rooting (65.63%) in vermiculite substrate (73.43%).

Autores: Santin, Delmar; Wendling, Ivar; Benedetti, Eliziane Luiza; Morandi, Divercindo.
O longo tempo necessário para produção de mudas por semente e a formação de ervais com material genético de baixa qualidade são problemas que necessitam ser superados na cultura da erva-mate. A enxertia na produção de mudas ou na substituição da copa de ervais poderá suplantar estas restrições. No entanto, a técnica ainda carece de maiores estudos, principalmente para materiais genéticos adultos. Assim, objetivou-se avaliar o efeito da enxertia seriada (subcultivos), clones, ambientes de enxertia e sexo das plantas matrizes na sobrevivência e vigor de enxertos de erva-mate. Para avaliar 3 subcultivos e 2 clones, instalou-se um experimento com mudas em viveiro. Em outro experimento compararam-se os ambientes campo e viveiro e seis clones (três masculinos e...

ABSTRACT  Grapevine (Vitis spp.) is a major vegetative propagated fruit crop with high socioeconomic importance worldwide. It is susceptible to several graft-transmitted agents that cause several diseases and substantial crop losses, reducing fruit quality and plant vigor, and shorten the longevity of vines. The vegetative propagation and frequent exchanges of propagative material among countries contribute to spread these pathogens, favoring the emergence of complex diseases. Its perennial life cycle further accelerates the mixing and introduction of several viral agents into a single plant. Currently, approximately 65 viruses belonging to different families have been reported infecting grapevines, but not all cause economically relevant diseases. The...

Effects of light on the propagation and growth of bulbs of Hippeastrum hybridum cv. Apple Blossom (Amaryllidaceae)
Provedor de dados: Scientia Agricola
Autores: Stancato,G.C.; Mazzafera,P.
Commercially bulbs of Hippeastrum hybridum are propagated by twin scales, which are cultured in wet vermiculite in the darkness until bulbil appearance. We showed that twin scales kept under sun light produced bulbils, that once transferred to the field, did not undergo severe light stress. They had higher bulb dry weight and due to the presence of green leaves they grew faster when transplanted to the field than bulbils produced from scales kept in the darkness. An intermediary treatment (a period of darkness followed by transference to light) confirmed the advantages of producing bulbils under sun light conditions. It appears that in the field, growth of bulbs from dark grown bulbils was retarded due to the strong competition among leaves and roots for...

Rooting of stem segments from fig tree cultivars
Provedor de dados: Acta Scientiarum: Agronomy
Autores: Bisi, Rayane Barcelos; Locatelli, Guilherme; Barbosa, Caio Morais de Alcântara; Pio, Rafael; Balbi, Rodrigo Vieira.
Although Brazil is the largest fig (Ficus carica L.) producer in the Southern Hemisphere, it mainly uses only one cultivar, ‘Roxo de Valinhos’. In addition, propagation is almost entirely through hardwood cuttings. Therefore, the aim of this study was to establish a propagation method that provides more successful rooting of stem segments of fig cultivars for the purpose of expanding the genetic base of the fig tree. The cultivars used were ‘Brunswick’, ‘Calabacita’, ‘Negro de Bursa’, ‘Mini Figo’, ‘Lampa Preta’, ‘Lemon’, ‘Troiano’,’ Nazaré’, ‘Três num Prato’, ‘Princesa’, ‘Colo de Dama’, ‘Montes’, ‘Bêbera Branca’, ‘Pingo de Mel’, and ‘Roxo de Valinhos’. The propagation methods used were layering, hardwood cuttings, nodal segments, herbaceous cuttings...

The difficulty and length of time required for seed germination of mate (Ilex paraguariensis), as well as the pressing need for clonal multiplication of improved genetic material, has resulted in several studies related to vegetative propagation in an effort to obtain rooted cuttings more quickly and with better genetic quality. Currently, the biggest challenge is propagating and rooting adult plants selected in the field without requiring clear cutting to generate conditions for the basal induction of juvenile sprouts. Therefore, the objective of this study was to develop a method to rescue adult mate plants through the generation of epicormic sprouts. To accomplish this, tree branches of mate that were at least 19 years of age were collected and packed...

Autores: Tovar-Pedraza,Juan M.; Mora-Aguilera,José A.; Nava-Díaz,Cristian; Téliz-Ortiz,Daniel; Valdovinos-Ponce,Guadalupe; Villegas-Monter,Ángel; Hernández-Morales,Javier.
Dieback of mamey sapote (Pouteria sapota) grafts is the most important disease during vegetative propagation in commercial nurseries. In 2008, Lasiodiplodia theobromae identified by cultural, morphological and molecular characterization was associated with this disease in 97 % of necrotic rootstocks and scions samples from a nursery in Guerrero, México. The fungus was inoculated onto the binding site of El Mexicano grafted plants. Dieback symptoms and gradual drying with cracking of the bark from the apex to the base of the scion were observed 30 d after inoculation. Abundant mycelia and pycnidia were found on inoculated scions and graft union areas, in the periderm, and on leaf scars. Transverse sections of inoculated scions tissues showed pycnidia....

Tree species sprouting from root buds in a semideciduous forest affected by fires
Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Rodrigues,Ricardo R.; Torres,Roseli B.; Matthes,Luis A. F.; Penha,Alessandra S.
Tree species which sprouted from root buds were identified in a 3.6ha area of a Semideciduous Seasonal Forest fragment in Campinas, São Paulo State (22° 55' S and 47° 05' W), affected by several fires. Connection between sprouts and main trunk root system was confirmed by digging and root exposure. Twenty seven tree species with root buds were identified, with a high proportion of Leguminosae species. The majority of identified species (45%) were characteristic of initial secondary succession stages. Distances between sprouts and main trunks varied from 0.6m (Guettarda viburnioides Cham. and Schltdl- Rubiaceae.) to 14.0m (Colubrina glandulosa Perkins- Rhamnaceae). These results lead discussions about natural and/or human-made disturbances influence on the...

Morphological aspects of the propagation in Heliconia velloziana L. Emygd. (Zingiberales: Heliconiaceae)
Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Simão,Daniela G.; Scatena,Vera L.
Morphology of seed and vegetative propagation was studied toHeliconia velloziana L. Emygd. (Heliconiaceae), a rhizomatous herb with a large aerial part. Seeds took about four months to germinate, probably due to the undifferentiated embryo and hard endocarp. Seedlings had two first foliar structures as scale leaves and the primary root developed, but the adventitious roots were more conspicuous. Vegetative propagation by rhizomes was faster than the sexual one. The roots developed after one month, while young shoots started developing after four to six weeks; young aerial shoots presented a variable number of cataphylls and two protophylls.

ABSTRACT: The aim of this research was to evaluate the feasibility of rescuing adult plants by cuttings from post-fire epicormic shoots. We evaluated the native tree species erva mate ( Ilex paraguariensis St. Hil.) and canjerana ( Cabralea canjerana Vell. Mart.), which present difficult seedling production and are economically and ecologically important. The plant material used for the preparation of cuttings consisted of shoots from bud differentiation of tissue from the stem collar of the trees. One-bud cuttings of erva mate were treated with 4000 or 8000mg L-1 of indolebutiric acid (IBA) and the checks were not treated with auxins. The cuttings were grown in three different substrates: carbonized rice husks, vermiculite and coarse sand. The experiment...
