1. What is the cause of low seed germination of Zanthoxylum rhoifolium Lam.?
ABSTRACT This study aimed to determine the main causes of low germination of Zanthoxylum rhoifolium Lam. (Rutaceae) seeds. Initially, the physical and physiological qualities were evaluated in seeds from four areas (lots) (Step I). Then, tests were performed (Step II) to determine physical dormancy (imbibition in water and methylene blue), physiological (ger

2. Efeito dos processos de irradiação e germinação nos aspectos nutricionais, sensoriais e microbiológicos em grãos de soja (Glycine m ax Merril) cultivar BRS216 / Effect of irradiation and germination processes in the nutritional, sensory and microbiological in soybeans (Glycine max Merrill) cultivra BRS216
Soybean (Gycine max (L.) Merrill) is an important legume for human diets due its potential health benefits. Because of the increasing stimulus to soybean consumption, mainly due to its several bioactive compounds, some processing methods have been studied as a way to know changes that occur in these compounds during the processes. Thus, this study aimed to a

3. Dormencia em sementes de maria-pretinha.
Maria-pretinha (Solanum americanum Mill), e uma planta invasora que produz nos campos grande quantidade de sementes com alta porcentagem de germinacao e viabilidade. Entretanto, suas sementes apresentam dormencia quando recem-coletadas e colocadas para germinar em temperaturas constantes de 25.C. O objetivo do presente trabalho foi determinar os fatores resp

4. Detecção e transmissão planta-semente de Colletotrichum gossypii South var. cephalosporioides Costa: efeito de níveis de incidência na semente e do controle químico da parte aérea sobre o progresso da ramulose do algodoeiro / Detection and transmission plant to seeds of Colletotrichum gossypii South var. cephalosporioides Costa. Effect of incidence levels in the seeds and the chemical control of the canopy on the progress of ramulosis of cotton
The ramulosis, caused by Colletotrichum gossypii var.cephalosporioides is one of the most important disease of cotton in Brazil. The fungus is transported and transmited by seeds and is an important initial inoculum source. The objectives of this research were i) to study the effect of germination inhibitors on the germination, length of radicle and incidenc

5. Conexão entre os processos de degradação das reservas de proteinas e carboidratos e o edfeito dos hormonios e açucares em sementes de Sesbania virgata (Cav.) Pers / Connection between storage proteins and carbohydrates degradation and the effects of hormones and sugars in seeds of Sesbania virgata (Cav.) Pers
Seeds of Sesbania virgata (Cav.) Pers. have an endosperm which accumulates galactomannan as a storage polysaccharide in the cell walls that is hydrolysed after germination by three enzymes (a-galactosidase, endo-ß-mannanase and exo-ß-mannosidase). Besides the storage of carbon, there is a great amount of protein bodies in the cytoplasm of endospermic cells

6. Identificação e caracterização de proteinas expressas no espaço intercelular de folhas de Theobroma cacao na interação com Moniliophthora perniciosa / Identification and characterization of proteins expressed in the intercellular space of leves from Theobroma cacao infected by Moniliophthora perniciosa
The invasion of the plant apoplast is a critical phase of the infection for numerous pathogens, including the fungus M. perniciosa (Mp) that remains in the intercellular space at the parasitic stage until about 60 days. Thus, the understanding of plant defenses induced in the apoplasm and the response mechanisms that the pathogens used for bypassing these de

7. TRATAMENTOS PRÉ-GERMINATIVOS VISANDO MINIMIZAR A DORMÊNCIA EM SEMENTES DE TUCUMÃ (Astrocaryum aculeatum G. MEY.)
This study evaluated the effect of water content and germination pretreatments on Astrocaryum aculeatum and identified possible causes of dormancy. A supplementary study was made in the anatomy and histochemistry of the seed integument. The emergence of plants was favored by soaking independent of temperature and period, but the lower mean time was in a 40C

8. FORMAÇÃO DE INIBIDORES BOWMAN BIRK DURANTE A GERMINAÇÃO DE Macrotyloma axillare
Proteomic analysis of Macroyiloma axillare Bowman-Birk inhibitors reveals the presence of only two species of 8 kDa with little variations on mass and charge which correspond to different proportions of amination of Glu and Asp residues present in molecules. The 120h-germinated cotyledons present several isoforms resulting from proteolytic processing which p

9. Production of Fabaceae sprouts for human consumption / ProduÃÃo de brotos de Fabaceae para o consumo humano
Germination is one of the most ancient, simple and economical processes to improve the nutritional value of grains, screening out of three Fabaceae (Fabaceae) species, the adequate germination period for human consumption, basing upon physiological, chemical and biochemical characteristics, being therefore, the main objective of this work. Seeds and sprouts

10. DORMÊNCIA E PRÉ-GERMINAÇÃO DE SEMENTES DE ARROZ
Several causes are pointed as responsible for the numbness in seeds of rice. The fenolic compounds have influence in the swinging between promoters and inhibitors of the germination of seeds, could represent an obstacle to the diffusion of gases. Several treatments are used with the purpose of overcoming the dormence in seeds and alternative methods appear t

11. Efeitos de diferentes métodos de quebra da dormência no perfil protéico de embriões de girassol (Helianthus annuus L.)
Dormancy may be regarded as a failure of an intact viable seed to complete germination under favorable conditions. The seeds of some species are prevented of completing germination because sometimes the embryo is constrained by its surrounding structures. It is named coat-imposed dormancy. In other especies the embryos themselves are dormant (embryo- or phys

12. ISOLAMENTO, PROPRIEDADES BIOQUÍMICAS E ESTUDOS BIOLÓGICOS DO INIBIDOR PROTEICO DA Macrotyloma axillare / Isolation, Bichemical properties and biological studies of proteic inhibitor of the Macrotyloma axillare.
The extracts of seeds and cotilédones of Macrotyloma axillare heat treatments the 90C for 30 min. followed by precipitation for cold etanol to obtain saturation of 60-80% results in the partial purification of inhibitors of protease of the type Bowman Birk. The isolation of the isoinhibitors with high text of purity is reached by means of ionexchange chroma
