Eugenia pyriformis Cambess. (uvaia), espécie arbórea tropical do Brasil, pode ser utilizada em programas de reflorestamento e em áreas urbanas e seus frutos apresentam potencialidade de uso industrial. Contudo, apesar da elevada porcentagem de germinação, a produção de sementes dessa espécie é insuficiente para produção de mudas em escala comercial. No presente trabalho, sementes de E. pyriformis foram cortadas longitudinalmente ou transversalmente em duas partes e mantiveram a elevada porcentagem de germinação e de produção de plântulas normais, mesmo quando a fração resultante do corte tinha apenas 1/4 da semente. Em um segundo experimento, as sementes foram cortadas em até oito partes e pelo menos uma das frações de cada semente continuou apresentando... |

This study was carried out to assess the genetic variability of ten "cagaita" tree (Eugenia dysenterica) populations in Southeastern Goiás. Fifty-four randomly amplified polymorphic DNA (RAPD) loci were used to characterize the population genetic variability, using the analysis of molecular variance (AMOVA). A phiST value of 0.2703 was obtained, showing that 27.03% and 72.97% of the genetic variability is present among and within populations, respectively. The Pearson correlation coefficient (r) among the genetic distances matrix (1 - Jaccard similarity index) and the geographic distances were estimated, and a strong positive correlation was detected. Results suggest that these populations are differentiating through a stochastic process, with restricted... |

O objetivo do presente trabalho foi o de estabelecer condições adequadas para testes de germinação in vitro do pólen de cerejeira-do-rio-grande (Eugenia involucrata DC), bem como verificar a possibilidade de armazená-lo em freezer (-16,5°C). O pólen foi coletado de flores em estádio de balão e logo após a antese. Os meios de cultura testados foram o meio padrão (10% de açúcar e 1% de ágar em água destilada) e este acrescido de duas concentrações de H3BO3 (0,65mM e 1,3mM). Foram testadas as temperaturas de incubação de 25 e 30ºC. O período de incubação foi de três horas, para todos os tratamentos. A incubação a 25°C, em meio de cultura-padrão, proporcionou boas médias (61,4%) de germinação in vitro. Pólen coletado de flores após a antese apresentou maiores... |

ABSTRACT: One of the biggest challenges for expansion of jabuticaba fruit tree cultivation is the high cost of seedlings due to to difficulties with vegetative propagation. Here, we aimed to evaluate graft survival in combinations of Plinia cauliflora and rootstocks of other species from the Myrtaceae family. The study was carried out at the Universidade Tecnológica Federal do Paraná - Campus Dois Vizinhos, Paraná State, Brazil. Eugenia uniflora L., E. involucrata DC, and P. cauliflora were used as rootstocks and were obtained as seeds. The 'whip-and- tongue' and cleft grafting techniques were tested for vegetative propagation. Grafted plants were cultivated in a greenhouse. The experimental design was a randomized complete block, in factorial 3×2... |

The objective of this work was to analyze the growth of champa fruit (Campomanesia lineatifolia) as a function of growing-degree days (GDD) in the municipality of Miraflores, in Boyacá, Colombia. Thirty trees were selected at random, and 100 flowers in full bloom were marked in each tree. From the 26th day after flowering until harvest, 10 samples were taken every 15 days to determine the fruit parameters and growth rate. Temperature was recorded to calculate the GDD. From flowering until harvest, 1,489.1 GDD were accumulated over 145 days. Dry and fresh matter mass of pulp, seed, and total fruit were fitted to a logistic growth model, and three growth stages (S1, S2 and S3) were defined. In the S1, growth was slow, and the relative growth remained nearly... |

ABSTRACT The Campomanesia rufa is a fruitful species native from Brazil considered as endangered by the IUC (International Union for Conservation of Nature) and low information regarding its propagation is available. In this context, the aim of the present study was to develop in vitro germination, micropropagation and callogenesis protocols for the species. For in vitro germination, seeds were inoculated in MS medium supplemented with GA3 (gibberellic acid) and for shoot induction, the medium was supplemented with three different cytokinins BA (benzyladenine), BAP (6-Benzylaminopurine) or TDZ (Thidiazuron). For shoot growth, culture medium containing BA, BAP, TDZ were maintained under white fluorescent lamps and blue:red light-emitting diodes (LED). GA3... |

The biotechnological techniques may help solve many problems of guava culture, such as the high perishability of fruits. Somatic embryogenesis can generate highly multiplicative cell cultures and with high regenerative potential, serving as basis for genetic transformation. The aim of this work was to obtain somatic embryogenesis of guava (Psidium guajava L.) cv. Paluma. Immature seeds were used, and they were inoculated in MS environment containing 400 mg L-1 of L-glutamine, 100 mg L-1 myo-inositol, 60 g L-1 sucrose, 100 mg L-1 ascorbic acid and supplemented with different types and concentrations of growth regulators. Embryogenic callus appeared after 37 days of culture in an environment containing 1.0 mg L-1 2.4-D + 2.0 mg L-1 2-ip, in 7% of the... |

ABSTRACT This study aimed to produce microcapsules using ‘jabuticaba’ byproduct through lyophilization, and evaluate the stability of the powder, intended for use in gelatin. Three formulations were prepared, including the pure lyophilized extract (E), capsule with maltodextrin (CapM), and capsule with maltodextrin and xanthan gum (CapMG). The storage stability was evaluated at 4 and 25 ºC, and in the presence and absence of light, regarding color parameters, phenolic compounds and monomeric anthocyanins. The microencapsulated powders were applied in gelatin and analyzed for sensorial acceptance. Following an investigation of the storage stability of the three powders at 4 °C for 60 days, the sample that presented the best result was then analyzed at 25 ºC... |

ABSTRACT Cerrado is the largest biome in the state of Minas Gerais-Brazil, represented by a biodiversity of fruit species, especially cagaita (Eugenia dysenterica). Cagaita fruits are considered an important option for fruit growing, because they are source of phenolic compounds with antioxidant properties and mineral content that can contribute with beneficial health effects. In this study, phenolic compounds were characterized by high-performance liquid chromatography and the mineral content of ripe and unripe cagaita fruits was evaluated. Regarding minerals, ripe and unripe fruits stand out due to their high potassium content. Unripe fruits are rich in boron while ripe fruits are source of this mineral. ripe and unripe cagaita fruits have the following... |

La familia Myrtaceae es una de las más numerosas en Argentina. En la provincia de Tucumán habitan 11 especies nativas, de las cuales Blepharocalyx salicifolius (Kunth) O. Berg, Eugenia uniflora L. y Myrcianthes pungens (O.Berg) D. Legrand presentan importancia medicinal, alimenticia y forestal. La información sobre las especies fúngicas y las modificaciones histológicas foliares que ellos producen es escasa. Por lo tanto, el objetivo de la presente investigación fue identificar las especies de hongos en hojas de las tres especies arbóreas y describir las modificaciones anatómicas causadas por la presencia de los mismos. Se trabajó con material fresco al que se aplicó técnicas y tinciones convencionales para su estudio. Se identificaron 12 especies... |

Esse estudo teve por objetivo caracterizar variações na arquitetura floral da Feijoa sellowiana e determinar sua influência sobre a polinização. Foram avaliados o comprimento do pistilo, a distância entre estigma e estames, o diâmetro de abertura e a distribuição dos estames na flor, com base em 7 flores de 15 acessos do Banco de Germoplasma da espécie. Distinguiram-se 3 classes de distâncias médias entre estigma e estames: 0,2 (C1), 0,7 (C2) e 1,2 cm (C3), e duas classes de distribuição de estames na flor (radial e aleatória). Sorteou-se uma planta por classe de distância entre estigma e estames, a qual teve 50 flores marcadas para cada um dos seguintes tratamentos: T1-polinização aberta; T2-tela contra pássaros e T3-tela contra pássaros e insetos. A... |
