| 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 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... |

| Lavandula species may be propagated by seeds. However, plants will present expressive variation both in size and essential oil content. Indole-3-butyric acid (IBA) is a growth regulator which efficiently stimulates rooting and the objective of this research was to observe the influence of different IBA concentrations on rooting of L. dentata cuttings. Herbaceous cuttings with approximately 10cm in length and around 1/3 of leaf retention had their bases submerged into 0 (control), 500, 1.000, 2.000 or 3.000mg dm-3 of IBA diluted in de-ionized water for 30 seconds and placed in polystyrene foam trays filled with commercial substrate and kept under intermittent mist system. Averages of root number, length of the longest root, fresh and dry root weight, and... |

| Plant regulators, as well as bioactive fractions of the organic matter, can accelerate the development and increase the efficiency of adventitious rooting in ornamental plants. We evaluated rooting in the Brazilian red-cloak (Megaskepasma erythrochlamys) and sanchezia (Sanchezia nobilis) cuttings in response to application of indole-butyric acid (IBA) and humic acids (HA). Stem cuttings of both species treated with solutions of 0, 250, 500, 1000, 2000 mg/L of IBA and 0, 10, 20, 30, 40 mmol/L of C of HA were placed in 2.0 L plastic pots containing carbonized rice husk, kept in greenhouse. Survival of cuttings, number of leaves and shoot and root fresh and dry matter were evaluated 45 days after. Data were used to run an analysis of variance. We observed the... |

| O Eucalyptus apresenta grande importância no setor florestal e muitos avanços na área do melhoramento foram conquistados com o advento da biotecnologia. Contudo, alguns genótipos promissores ainda não possuem protocolos de multiplicação com técnicas de clonagem, como a miniestaquia. Objetivou-se avaliar concentrações de IBA na sobrevivência, enraizamento e vigor vegetativo de miniestacas de E. benthamii x E. dunnii, com a determinação da dose de máxima eficiência técnica. Minicepas dos clones H12, H19 e H20 foram manejadas em minijardim clonal em sistema semi-hidropônico. Para o enraizamento, mergulhou-se a porção basal da miniestaca em soluções hidroalcoólicas, cujas concentrações foram: 0, 2.000, 4.000, 6.000 e 8.000 mg Lde IBA. O experimento foi... |

| 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%). |

| The objective of this work was to evaluate different densities of rootedproductivity and survival as well as the effects on production and survival of cuttings produced. We performed two separate experiments, one for each genetic material (C1 and C2) and were assessed three densities for clone C1 (88, 75 and 57 ministumps m-2) and two for clone C2 (104 and 78 ministumps m-2). Shoots we collected from the ministumps and they were used in making cuttings 6-10 cm long. Sampling was initiated in January 2011, ending in March 2011. The cuttings were planted in substrate composed of 50% vermiculite and 50% of rice hulls and subsequently they were conducted in following steps: greenhouse, shade house and field hardening. For both clones, the density with smaller... |

| The main scope of this work was to detect (Panicum maximum Jacq.) genotype differences as to morphoagronomic and seed quality indices, and to establish character correlations useful for determining vegetative and reproductive trends. Besides the flowering cycle, eight phenological and two seed quality traits were scored in a greenhouse randomized complete block experiment, as follows: plant height (PH), reproductive tiller number/overall tiller number (RTN/OTN), panicle number/reproductive tillers (PN/RT), leaf length (LL), leaf width (LW), panicle length (PL), fresh weight (FW), dry weight (DW), number of seeds/g (NS/G) and seed sample physical purity (SPP). Very-early and early-flowering hybrids consistently showed the highest correlation values among... |

| 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... |
