Adição de condicionadores orgânicos e inorgânicos em substrato comercial para o cultivo em vasos de Melocactus violaceus subsp. violaceus. Infoteca-e
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.

Advances observed in papaya tree propagation Rev. Bras. Frutic.
Costa,Adelaide de Fátima Santana da; Abreu,Emanuel Felipe Medeiros; Schmildt,Edilson Romais; Costa,Aureliano Nogueira da; Schmildt,Omar.
Abstract Papaya (Carica papaya L.) is a fruit tree of great economic and food interest worldwide. Its propagation can occur both sexually and asexually. Traditionally, it is propagated by seeds; however, vegetative propagation has been often used with the use of in vitro and ex vitro culture techniques. In vegetative propagation, the cutting method has been extensively explored. Research has also been developed using grafting. In recent years, papaya cultivation has also become a model for other fruit plants in the use of biotechnological techniques aiming applications ranging from germplasm conservation to genetic transformation of plants. Since the beginning of the 1970s, the culture of papaya tree tissues has been intensely studied, allowing greater...

Asexual propagation of peach palm by division of the clump and extraction of the off-shoots Horticultura Brasileira
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...

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%).

Bisognin,Dilson Antônio; Lencina,Kelen Haygert; Kielse,Paula; Fleig,Frederico Dimas; Silveira,Ronilda; Gimenes,Eliseo Salvatierra.
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...

Effects of light on the propagation and growth of bulbs of Hippeastrum hybridum cv. Apple Blossom (Amaryllidaceae) Scientia Agricola
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...

Enxertia seriada de erva-mate em viveiro e campo PFB - Pesquisa Florestal Brasileira
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...

Grafting of Araucaria angustifolia (BERTOL.) kuntze through the four seasons of the year Rev. Bras. Frutic.
Zanette,Flávio; Oliveira,Liege da Silva; Biasi,Luiz Antonio.
Araucaria angustifolia is an endangered conifer species of South America that has been over exploited for timber. To incentivize Araucaria angustifolia planting is essential and may play a key role on the conservation of this species and the ecosystems that depend on it. Hence, techniques that allow the production of seedlings with attributes that may entice farmers to plant A. angustifolia trees are very important. Grafting may permit the selection of female trees and the production of precocious plants that will produce high quality seeds. The aim of this study was to determine the best season of the year to graft. Three-year-old seedlings were used as rootstock and orthotropic branches of young plants were used for scion collection. The technique used...

GRAPEVINE VIRUS DISEASES:ECONOMIC IMPACT AND CURRENT ADVANCES IN VIRAL PROSPECTION AND MANAGEMENT Rev. Bras. Frutic.
BASSO,MARCOS FERNANDO; FAJARDO,THOR VINÍCIUS MARTINS; SALDARELLI,PASQUALE.
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...
