1. Osmotic conditioning and shading on the germination and on the initial growth of Myracrodruon urundeuva Allemão seedlings
O presente trabalho objetivou avaliar o condicionamento osmótico e o sombreamento na germinação e no crescimento inicial de mudas de aroeira. As sementes foram pré-embebidas em soluções de diferentes concentrações de PEG (Polietilenoglicol) e KNO3 e incubadas em temperatura de 10°C e 20°C durante 0 (controle), 12 e 24 horas. Após estes períodos a

2. Avaliação do condicionamento fisiológico e aplicação de fósforo em sementes de milheto / Physiological conditioning and phosphorous application on pearl millet seeds
Beside the many aptitudes of the pearl millet (stock feeding, hay, soil layer protection and food in general), some factors limit its expansion in Brazil, being generally, the low physical and physiological seed quality on the market as one of the harshest problems. Thus, this study aimed at applying physiologic conditioning techniques, pelleting and phospho

4. ASPECTOS FISIOLÃGICOS E BIOQUÃMICOS DA MATURAÃÃO DE SEMENTES DE PIMENTÃO. / Physiological and biochemical aspects of the maturation of sweet pepper seeds
The determination of the appropriate point or interval for the harvest of fruits for sweet pepper seed production is fundamental for success in production programming, as well as for obtaining quality seeds. From their physiological maturity period up to the moment they are used for sowing, the seeds are subject to loss of physiological quality due to the oc

5. Qualidade fisiológica e pré-condicionamento de sementes de cultivares de soja de diferentes grupos de maturidade em três épocas de colheita / Physiologic quality and pre-conditioning of soybean seeds cultivars with different maturity groups in three harvesting times
The use of quality seeds in soybean plantations is fundamental to guarantee fast and appropriate establishment of the stand. The objective of this work was to evaluate the physiologic quality of soybean seeds harvested in three times and submitted to the osmotic conditioning. Seeds of the soybean cultivars with different maturity groups: Confiança (semi-pre

8. EFEITO DO CONDICIONAMENTO FISIOLÓGICO SOBRE O DESEMPENHO DE SEMENTES PARA PRODUÇÃO DE FORRAGEM HIDROPÔNICA / EFFECT OF PHYSIOLOGICAL CONDITIONING SEEDS PERFORMANCE TO PRODUCE HYDROPONIC GRASS
A produção de forragem no sistema hidropônico necessita usar sementes de alta qualidade, no entanto, nem sempre se dispõe de material em quantidade e qualidade exigidas para o sucesso da produção. Visando melhorar o desempenho fisiológico das sementes tem sido recomendados os tratamentos de condicionamento osmótico e pré-germinação, a fim de aumen

9. Twenty-Four-Hour Induction of Freezing and Drought Tolerance in Plumules of Winter Rye Seedlings by Desiccation Stress at Room Temperature in the Dark 1
Exposure of seedlings of winter rye (Secale cereale L., cv. Puma) for 2 weeks or 24 hours to desiccation stress (40% relative humidity) at room temperature (21°C) in the dark induced degrees of freezing and drought tolerance in the plumules comparable to those produced by cold conditioning for 2 weeks at 3°C. The induction was associated with repression of

10. Characterization of Spiroplasma mirum (suckling mouse cataract agent) in a rabbit lens cell culture.
Spiroplasma mirum (suckling mouse cataract agent) was studied in an epithelial cell line AG-4676, derived from rabbit eye lens. Rabbit eye lens is a natural target tissue of S. mirum infection. The organism grew rapidly in this cell line, reaching titers of 10(7) to 10(9) color change units per ml at 7 days after infection. This is the same level as that ach
