1. Esporulação in vitro e inoculação de Exserohilum turcicum em milho
RESUMO A helmintosporiose está entre as principais doenças da cultura do milho. Realizou-se dois ensaios com os objetivos de avaliar a esporulação do fungo diferentes meios de cultura, métodos de inoculação e concentrações de inóculo para Exserohilum turcicum. Para a esporulação em diferentes meios de cultura, testou-se seis diferentes substratos

2. In vitro adventitious shoot regeneration from leaf explants of some apricot cultivars
RESUMO O damasco é considerado uma das frutas mais valiosas comercialmente. A propagação in vitro de damasco é muito importante para a multiplicação de cultivares com características desejáveis, saudáveis e livres de vírus. O fator limitante para a propagação por métodos convencionais é a baixa frequência na multiplicação. Nesse contexto, o

3. New technologies from the bioworld: selection of biopolymer-producing microalgae
Abstract Microalgae are studied because of their biotechnological potential. The growth of microalgae aims at obtaining natural compounds. Due to the large amount of accumulated polymer waste, one of the solutions is the use of biodegradable polymers. The objective of this work was to select biopolymer-producing microalgae and to study the cell growth phase

4. Mass spore production and inoculation of Calonectria pteridis on Eucalyptus spp. under different environmental conditions
Calonectria pteridis is one of the most important causal agents of Calonectria leaf blight (CLB) of Eucalyptus spp. in Brazil, which is a limiting factor for growth of Eucalyptus plantations. In this study we developed standard procedures for in vitro mass spore production and inoculation of C. pteridis for screening plant species and clones for resistance t

5. Germination and sporophytic development of Regnellidium diphyllum Lindm. (Marsileaceae) in the presence of copper
Regnellidium diphyllum Lindm. is a heterosporous fern growing in wetlands and humid soils that are being converted to agricultural activities. Many products that are used in agriculture contain copper, resulting in surface and groundwater contamination. Germination and initial development tests were performed using Meyer's solution containing copper sulphate

6. Discriminated conditioned suppression in rats
This experiment evaluated the effects of superimposing the Estes-Skinner Conditioned Emotional Response (CER) procedure on one of two components of a multiple schedule. The question was whether CER conditioning occurred under contextual control. The procedure had four experimental phases: (1) baseline of operant responding under a two-component multiple sche

7. Biologia e manejo de Chalcodermus bicolor Fiedler (Col.: Curculionidae: Molytinae), em plantios de eucalipto / Biology and management of Chalcodermus bicolor Fiedler (Col.: Curculionidae: Molytinae), in eucalypt plantations
This work deals to the biology and pest management aspects of the “Eucalypt-trimmer”, a new leaf beetle in the Brazilian eucalypt plantations. Works were developed under lab conditions (Temperature = 25.29 0.20C; RH = 78.26 0.94%; photophase: scotophase = 10:14 hours). Insects were collected from cloned eucalypt in the Mucuri and Caravelas counti

8. Germinação de sementes de crotalária e de alface com o preparado homeopático de ácido giberélico / Germination of seeds of sunn hemp and lettuce with the homeopathic preparation to gibberellic acid
The effect of gibberellic acid ultradiluted (dynamizations 1CH to 12CH) on germination of lettuce and sunn hemp seeds was evaluated. The sunn hemp seeds were stored in cold chamber per one year and kept for six months under refrigeration before receiving homeopathic preparations in the water from imbibition during two hours. After that the seeds were placed

10. Comportamento germinativo de espécies do gênero Stachytarpheta Vahl. (Verbenaceae) ocorrentes nos campos rupestres da Cadeia do Espinhaço em Minas Gerais
The present work studied the seed germination ecology of thirteen Stachytarpheta Vahl species, twenty-two populations and a hybrid between S. glabra Cham. and S. confertifolia Mold., occurring in the Rock Outcrops of the Espinhaço Range in its Minas Gerais state portion, in Brazil. Were evaluated biometrics, light and temperature influences, in addition to

11. Instalações de câmera escura em espaços cotidianos: o espaço modificado e a meta-câmera fotográfica / Instalações de câmera escura em espaços cotidianos: o espaço modificado e a meta-câmera fotográfica
Esta dissertação parte de um levantamento sobre as possibilidades da câmera escura para lidar com as interferências na percepção do espaço e na formação da imagem fotográfica ao entrarmos em câmeras escuras instaladas em espaços cotidianos. A experiência estética se divide em dois momentos. No primeiro, o habitante autoriza que um espaço de su

12. Ferrugem asiática da soja: métodos de preservação dos urediniósporos e fatores relacionados à infecção do hospedeiro / Asian soybean rust: methods for uredospores preservation and factors related to host infection
Soybean is the agricultural crop with the largest planted area in Brazil. The country stands out in the world scenario as the second-largest producer and exporter of this oilseed crop. The Asian rust (AR), caused by the fungus Phakopsora pachyrhizi, is one of the most serious phytosanitary problems of soybean in Brazil, especially because no cultivars exist
