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 Precision mechanized sowing of sugarcane has been delayed due to germination failures caused in sowing process by pieces of sugarcane, generating economic losses by reducing production. The aim of this study was to evaluate different polymers and cultivars of sugarcane to elaborate artificial seed CP-54, seed germination and quality of sugarcane plants. An experiment was carried out in two stages in experimental field of the Colegio de Postgraduados Campus Tabasco, Mexico. Results indicate that the best physical stage of artificial seed CP-54 was obtained in Mex 69-290, Mex 68-P-23 and CP 72-2086 cultivars encapsulated with starch polymers and sodium alginate. Artificial seed CP-54 germination was 100 and 84% encapsulated with starch and alginate... |

The effects of different salinities on the germination of Spartina ciliata seeds were tested during 40 days in the laboratory, using six concentrations of NaCl (0,45, 80, 130, 170 and 215 mM) besides three concentrations of seawater (25,30 and 35‰). In addition, the survival and growth of seedlings were tested in five constant salinity regimes (0,45, 80 and 170 mM NaCl) as well as in five regimes of simulating seawater overwash. The results showed that seeds possed a high germination capacity over a wide range of salinities (0 to 215 mM NaCl). Although concentrations close to full-strength seawater completely inhibited seed germination, the transfer of the ungerminated seeds to freshwater immediately stimulated this. The effects of salinity on seedling... |

ABSTRACT Copaifera oblongifolia is a recurrent plant species in degraded areas yet there is little information about its seed biology and interactions with fungi. The aims of this study were to identify the fungal community (endophytic and non-endophytic) associated with C. oblongifolia seeds and to test the effects of these different fungal species on germination. In general, germination of C. oblongifolia seeds was high (about 85 %), initiating four days after sowing and continuing for a total of 20 days. External asepsis with sodium hypochlorite did not influence germinability of C. oblongifolia. Seed infestation with Aspergillus niger, A. flavus, Mucor sp. and Rhizopus stolonifer did not affect the time required for germination, however, infection with... |

ABSTRACT Seed predation is a natural phenomenon that can occur either before or after dispersal and can significantly reduce the economic value and reproductive potential of plants. The babassu palm (Attalea vitrivir, Arecaceae) is important to rural communities that extract oil from its fruits for a wide variety of uses. We evaluated the predation and germination of A. vitrivirseeds in Pandeiros River Environmental Protection Area (EPA-Pandeiros) in Minas Gerais State, Brazil. Sixty individual plants were evaluated to determine their fruiting patterns. Seed predation and germination were evaluated in the natural environment for eight months for fruits divided into two treatments: scarified and intact. Germination of fruits submitted to these same... |

A qualidade das sementes colocadas à disposição do produtor é de grande importância para obtenção de altas produtividades. O objetivo do trabalho foi avaliar os efeitos causados por diferentes períodos de envelhecimento artificial na lixiviação de açúcares, proteínas, aminoácidos e íons no exsudato do teste de condutividade elétrica, e suas relações com a germinação e vigor de sementes de feijão da cultivar Pérola. O trabalho foi conduzido no Laboratório da FE de análises de sementes - Unesp Campus de Ilha Solteira. O delineamento experimental foi o inteiramente casualizados, sendo que as sementes foram submetidas a oito períodos de envelhecimento acelerado (zero, 24, 48, 72, 96, 120, 144 e 168 horas). A germinação e vigor de sementes de feijão cultivar... |

Seed germination of fig seeds is important for obtain seedlings with high variability in breeding studies, and for producing mosaic virus-free seedlings. This experiment was carried out to evaluated the effects of several treatments (priming with water for 24h, GA3 at 500 and 1000 ppm for 24h, 3% KNO3 for 24h, and stratification at 4°C for 7, 14 and 21 days) on seed germination and emergence of ‘Bursa Siyahı’ and ‘Sarılop’ fig cultivars. The application of GA3 increased the germination and emergence of these fig seeds. The highest percentages of germination and emergence were obtained with GA3 at 500 or 1000 ppm for both cultivars. The seed germination and emergence of the cultivar ‘Bursa Siyahı’ were higher than observed with the ‘Sarılop’. The... |

Abstract Various studies have been undertaken to evaluate the effect of polymer-based encapsulation on performance of plant growth promoting microorganism. However there is no systematic analysis about the performance of these microorganisms when encapsulated in a polymer-based matrix. Relevant published papers were retrieved by conducting searches in Google Scholar, Only Library, Science Direct, Springer Journal, Taylor & Francis and Wiley Online Library. An examination of 117 articles was carried out and of those only 11 satisfied our criteria for inclusion into the meta-analysis. From these articles, we selected 41 cases to be evaluated. We used as keywords “microcapsules”, “capsules”, “microorganisms”, “growth”, “promoting”, “germination”... |
