1. Reduced sensitivity to azoxystrobin is stable in Monilinia fructicola isolates
ABSTRACT A shift towards declining azoxystrobin sensitivity has been previously documented in a collection of Brazilian Monilinia fructicola isolates, but information on the stability of this trait after in vitro sub-culturing is not available. In this study, one highly-sensitive isolate and two isolates with reduced sensitivity to azoxystrobin, not exhibiti

2. Qualidade de sementes de soja convencional e transgÃnica apÃs colheita e durante armazenamento em condiÃÃo ambiente e em resfriamento / Seed quality of conventional and transgenic soybean after harvest and storage in warehouse and cooling conditions
In a scenario where there is increasing production of soybeans, the quality of the storaging process is a factor of increasing concern, which requires the incorporation of technologies and production systems research in seed companies, adopting measures to ensure the viability of the seed during storage. This study aimed to evaluate the quality of seeds of f

3. Germination, carbohydrate composition and vigor of cryopreserved Caesalpinia echinata seeds
The present study investigated the germination and vigor of Caesalpinia echinata (Brazilwood) seeds stored at negative temperatures. Recently harvested seeds were cryopreserved at -18º or -196ºC and periodically evaluated for germination, seed vigor and carbohydrate composition. The temperatures did not influence the germination percentages or vigor. The g

4. Padrão de germinação de sementes e estabelecimento de mudas de guanandi (Calophyllum brasiliense Cambess.)
CHAPTER II: Calophyllum brasiliense Cambess. is a tree, typical of tropical rainforests, with seed germination variable and uneven due to restrictions of the layers of the integument. The objective was to characterize the dormancy of seeds of species by their ability to soak, germination, emergence, distribution of germination over time and the timing and qu

5. Tamanho ótimo de amostra para análise da qualidade fisiológica de diásporos de espécies florestais nativas do cerrado / Optimum sample size for analysis of the physiological quality of diaspores from Savannahs woody species
Quais as conseqüências de se trabalhar com tamanhos de amostra diferentes? Quais as conseqüências disto sobre a qualidade dos resultados obtidos? Qual o tamanho mínino de amostra necessário para que os resultados das medidas de germinação sejam representativos da população? Pensando nisto, objetivou-se neste trabalho avaliar diferentes tamanhos de

6. Estádio de maturação dos frutos, tratamentos pré-germinativos e variabilidade da emergência de plântulas de morototó (Schefflera morototoni)
The objective of this work was to evaluate the influence of the fruit maturation stage in the physical attributes and germination of Schefflera morototoni pyrenes subjected to pre-germination treatments. Fruits with green and purplish green coloration were collected from 14 individuals, pulped in running water, the hollow pyrenes were discarded after countin

7. Efeito dos extratos do albedo de Citrus sinensis, Lentinula edodes, Agaricus blazei e dos compostos orgânicos voláteis produzidos por Saccharomyces cerevisiae no controle da mancha preta dos citros / Effect of albedo extracts of Citrus sinensis, Lentinula edodes, Agaricus blazei and volatile organic compounds produced by Saccharomyces cerevisiae in the control of citrus black spot
The citrus black spot is a disease that restricts the export of Brazilian oranges to the countries in Europe. Except for Citrus aurantium and its hybrids, all other varieties are susceptible to the pathogen. Thus, there is great interest that this disease does not occur, since it is considered a quarantine A1 disease. Problems associated with the acquisition

8. Efeito da quitosana e da radiação UV-C no controle de Guignardia citricarpa em laranja pós-colheita / Effect of chitosan and UV-C on the control of Guignardia citricarpa on postharvest orange
Brazil is the biggest producer and exporter of orange juice, and this is one of the most important economical activities for the country. The fruits can be affected by the citrus black spot, disease caused by the fungus Guignardia citricarpa, which depreciates then commercially, causes premature fall and increases the production cost. Alternative measures to

9. Efeitos das condições de armazenagem sobre a qualidade da soja (Glycine max (L.) Merrill) e do óleo bruto / Effects of storage conditions on the quality of soybean grains (Glycine max (L.) Merrill) and crude oil
Brazil s 2005/06-grain production is forecast at approximately 123 million tons. Of this total, Brazil should produce 57 million tons of soybean grains, i.e., 46% of the national production. Brazilian agricultural production, however, needs to meet the international demands in order to gain foreign markets, maintaining good quality of grains is therefore ess

10. AvaliaÃÃo do crescimento e de mecanismos de tolerÃncia à salinidade em plantas de sorgo forrageiro irrigados com Ãguas salinas / Evaluation of the grown and mechanisms of tolerance to the salinity in plants of forrage sorghum (Sorghum bicolor (L) Moench), irrigated with saline waters.
This work studied the tolerance of two genotypes of forrage sorghum (Sorghum bicolor (L) Moench), one salt sensitive (CSF 18) and another salt tolerant (CSF 20). Selected seeds were germinated in vases containing 12 Kg of sandy soil under greenhouse conditions. Ten days after seeding, plants were irrigated with different salt concentration water. For prepair

11. Reduced Germination of Clostridium botulinum Type A Spores In Vitro by Polymorphonuclear Leukocytes from Chronic Granulomatous Disease
Leukocytes from two patients with chronic granulomatous disease of childhood (CGD) and from one female carrier were examined for their capacity to induce germination of Clostridium botulinum type A spores in vitro. Normal human leukocytes induced germination of C. botulinum spores to the same extent as guinea pig neutrophils. Germination was depressed by mor
