| Este trabalho objetivou caracterizar biometricamente sementes e frutos de Hymenaea courbaril L. e determinar o grau de umidade, bem como avaliar diferentes tratamentos de superação de dormência. Foram determinados a biometria, a massa de frutos e sementes e o número de sementes por fruto. As sementes foram submetidas aos seguintes cortes: 1-testemunha, sem escarificação ou corte; 2-escarificação em três faces; 3-corte ao meio e 4-corte em quatro partes. Avaliou-se também o percentual de emergência, o IVE, o comprimento da parte aérea e da raiz de plântulas. Para isso, as sementes foram submetidas à superação de dormência, com e sem embebição em água, pelos seguintes tratamentos: I-escarificação do lado oposto ao hilo; II-escarificação em uma lateral;... |

| In order to characterize geometrically seeds and fruits of flamboyant grown in Vitória da Conquista city, BA has developed this work at the State University of Southwest Bahia. Were determined biometrics, the mass of fruits and seeds and number of seeds per fruit. The collection of fruits was held in headquarters trees located in the urban area of Vitória da Conquista, Bahia, where we selected 30 fruit and 100 seeds, which were evaluated its length and diameter and thickness. The fruits and seeds Flamboyant showed wide variability in the characteristics evaluated. |

| Extracts of many plant species have shown nematicide activity attributable to phytochemicals present in their tissues or formed during a degradation process. Nevertheless, before the application of plant compounds in the field, it is necessary to know their effect on plant hosts. Three concentrations (1, 2.5 and 5% w/w) of dry leaves of Buddleja globosa, Drymis winteri, Eucalyptus globulus, Gevuina avellana, Laurelia sempervirens and Ugni molinae were evaluated on growth parameters (plant height, root length and leaf dry matter) in plants of Lactuca sativa infested with Meloidogyne hapla. Lettuce growth parameters were significantly affected by the interaction between the species and dry leaf tissues concentrations. Drymis winteri showed the biggest... |

| The biological control of the root-knot nematode, Meloidogyne hapla , was evaluated through the addition of organic amendments of dry and chopped leaves of Buddleia globes, Dramas winter, Eucalyptus globules, Genuine aflame, Aurelia sempervirens, huma apiculata, Maytenus boaria and Ugni molinae to the soil substratum. The assays were carried out in pots seeded with lettuce plants (cv. Reina de Mayo). All pots were inoculated with 2000 eggs and juveniles of M. hapla, and then maintained under greenhouse conditions for 45 days. Control pots without foliage additions were also seeded with lettuce. The results show that the addition of dry leaves of L. sempervirens, G. avellana, M. boaria, D. winteri , and B. globosa significantly reduced root-knot nematode... |

| ABSTRACT The tetrazolium test is one of the promising alternatives to determine the viability of dormant, recalcitrant and slow-germinating seeds. The objective of this study was to adapt the tetrazolium test methodology to estimate the viability and vigor of Piptadenia stipulacea (Benth.) Ducke seeds. For this, a sample of seeds was classified into three sublots using round sieves, corresponding to six, five and four millimeters in diameter, respectively. Moisture content, imbibition curve, germination, emergence, germination and emergence speed indices, mean germination time and seedling emergence were initially evaluated. The second stage was conducted using a completely randomized experimental design, in 3 x 9 factorial scheme, corresponding to three... |
