1. Physiological potential and initial development of soybean plants as a function of seed treatment
RESUMO O tratamento de sementes é um processo que auxilia no controle de insetos e patógenos iniciais, além de possibilitar à cultura atingir seu potencial máximo de produção e promover proteção à plântula. Objetivou-se avaliar o desempenho fisiológico de sementes e o desenvolvimento inicial de plantas de soja, em função do tratamento de sement

2. Beneficial effects of bio-controlling agent Bacillus cereus IB311 on the agricultural crop production and its biomass optimization through response surface methodology
ABSTRACT Disease in agricultural field is a big problem that causes a massive loss in production. In this present investigation, we have reported a soil-borne bacterium Bacillus cereus IB311 which is antagonistic to plant pathogens (Pseudomonas syringae and Agrobacterium tumefaciens), and could make a substantial contribution to the prevention of plant disea

3. Rapid PCR-based assay for Sclerotinia sclerotiorum detection on soybean seeds
Caused by Sclerotinia sclerotiorum, white mold is an important seed-transmitted disease of soybean (Glycine max). Incubation-based methods available for the detection and quantification of seed-borne inoculum such as the blotter test, paper roll and Neon-S assay are time-consuming, laborious, and not always sensitive. In this study, we developed and evaluate

4. Supression of seed borne Cladosporium herbarum on common bean seed by Trichoderma harzianum and promotion of seedling development
Trichoderma harzianum isolates have been broadly used for biocontrol of plant diseases caused by fungi. Cladosporium herbarum is a common saprophyte and seed borne fungus, which is easy to manipulate under controlled conditions. It was chosen as a model to test the effectivity of seed treatments with T. harzianum. Common bean seeds (cv. Pérola) contaminated

5. Biological control of Fusarium oxysporum f. sp. phaseoli by Trichoderma harzianum and its use for common bean seed treatment
Biological control of seed-borne pathogens has shown to enhance germination and physiological quality of seeds. The objectives of this study were to evaluate the in vitro antagonistic effect of five Trichoderma harzianum isolates (CEN287, CEN288, CEN289, CEN290, and CEN316) against Fusarium oxysporum f. sp. phaseoli (Foxy) and test its potential use in seed

6. Seed-borne pathogens and electrical conductivity of soybean seeds
Adequate procedures to evaluate seed vigor are important. Regarding the electrical conductivity test (EC), the interference in the test results caused by seed-borne pathogens has not been clarified. This research was carried out to study the influence of Phomopsis sojae (Leh.) and Colletotrichum dematium (Pers. ex Fr.) Grove var. truncata (Schw.) Arx. fungi

10. Viral determinants associated with the distinct biological properties of two isolates of Lettuce mosaic virus (LMV): Kinetics of viral infection and infection of the embrionary tissues / Determinantes virais associados às diferentes propriedades biológicas de dois isolados de Lettuce mosaic virus (LMV): cinética da infecção viral e infecção dos tecidos embrionários
Lettuce mosaic, caused by the potyvirus Lettuce mosaic virus (LMV), is one of the main diseases of lettuce. The type strain of the virus includes isolates which are seed borne in lettuce, but which cannot infect lettuce cultivars harboring the recessive resistance aleles mo11 e mo12. The Most strain includes isolates which are also seed borne and can infect

11. Trichoderma spp. ON PLANT GROWTH AND BIOCONTROL OF Sclerotinia sclerotiorum AND SEED PATHOGENS OF CARTHAMUS (Carthamus tinctorius) / Trichoderma spp. NO CRESCIMENTO VEGETAL E NO BIOCONTROLE DE Sclerotinia slcerotiorum E DE PATÓGENOS EM SEMENTES DE CÁRTAMO (Carthamus tinctorius)
The cultivation of flowers is, in Brazil, very recent and little known species have a high ornamental potential, Cartamus is such a species and there are cultivars for the production of oil and as well as for ornamental pourposes. Being a recent crop in Brazil, little is known about its associated diseases, specially those that affect the seeds and the soil

12. Effects of some phenolic compounds on soybean seed germination and on seed-borne fungi
Os compostos fenólicos são metabólitos secundários importantes na ecologia vegetal, especialmente em relações alelopáticas e interações com microorganismos, sendo sintetizados principalmente através da via do ácido chiquímico. Neste trabalho, os efeitos de cumarina, ácido ferúlico e naringenina sobre a germinação de sementes de soja e sobre o
