1. Nutritional deficiency symptoms of young ‘cedro doce’ plants grown under macronutrient omission
RESUMO O cedro doce [Pochota fendleri (Seem) Alverson & Duarte] é uma espécie florestal nativa da Amazônia e com expressiva importância ecológica e econômica. Conhecer as exigências nutricionais da espécie permite cultivar o cedro doce com práticas de adubação mais eficientes desde a sua fase de muda. Sendo assim, o objetivo desta pesquisa foi ava

2. Nutrientes e fungos micorrízicos arbusculares como fatores limitantes ao crescimento de Toona ciliata M. Roem. var. australis. 2010. / Nutrients and arbuscular mycorrhizal fungi as factors limiting the growth of Toona ciliata M. Roem. var. australis. 2010.
O presente trabalho teve como objetivo avaliar alguns fatores limitantes ao crescimento de Toona ciliata M. Roem. var. australis (cedro-australiano). No capítulo I, avaliou-se o crescimento de mudas de cedro-australiano inoculadas com fungos micorrízicos arbusculares (FMAs), Acaulospora laevis, A. morrowiae, Entrophospora colombiana, E. contigua, Gigaspora

3. Crecimiento inicial de Palo de Rosa (Aniba rosaeodora Ducke) en distintos ambientes de fertilidad
Studies of nutritional requirements are of great importance for identifying the most important nutrients in physiologic development and seedling growth. A greenhouse pot experiment was conducted at INPA to evaluate the mineral nutritional demands and the effects of macronutrient omission in the plant growth of Aniba rosaeodora Ducke. The following treatments

4. NutriÃÃ Mineral em Plantas de Copo de Leite: DeficiÃncia de Nutrientes e AdubaÃÃo Silicatada / Mineral nutrition of calla lily plants: nutrients deficiencies and silicon fertilization
The aspects related to mineral nutrition in ornamental plants are very important to the production of quality flowers. In the specific case of the calla lily (Zantedeschia aethiopica) the information on nutrition and manuring in commercial cultivations are quite incipient. Thus, the objectives of this work were to evaluate the deficiencies of nutrients and d

5. Vegetal development, production and chemical composition of essential oil of Cordia verbenacea DC (Boraginaceae), in relation to N, P, K and B supply and Jasmonic acid application / Desenvolvimento vegetal, produção e composição quimica do oleo essencial de Cordia verbenacea DC. (Boraginaceae) em função do fornecimento de N, P, K e B e da aplicação de acido Jasmonico
The essential oil of Cordia verbenacea, a native Brazilian medicinal plant, presents anti-inflammatory properties. Due to its therapeutic properties, there is great interest in expanding research on it. The present study investigates the effect of mineral nutrition and jasmonic acid application on this plant´s development, yield, chemical composition, and e

6. NUTRIÇÃO MINERAL E TOXIDEZ DE CÁDMIO EM GINSENG BRASILEIRO (Pfaffia glomerata (Spreng.) Pedersen) / MINERAL NUTRITION AND CADMIUM TOXICITY IN BRAZILIAN GINSENG (Pfaffia glomerata (Spreng.) Pedersen)
Pfaffia glomerata (Spreng) Pedersen, also known as Brazilian ginseng, has been used in popular medicine due to its important medicinal qualities. This study aims to characterize the nutrient needs of P. glomerata, (Chapter 1) as well as to assess the tolerance of this plant to high levels of cadmium in the substrate (Chapter 2). P. glomerata plants produced

7. Senescence of Pear Fruit Cells Cultured in a Continuously Renewed, Auxin-deprived Medium
Auxins and cytokinins support cell division in tissue and cell cultures. In cytokinin-independent pear (Pyrus communis) cells, omission of 2,4-dichlorophenoxyacetic acid (2,4-D) from the medium for two successive transfers leads to rapid cell lysis, unless the osmolarity is raised to 0.4 molar with mannitol. Use of this system (nutrients plus mannitol minus

8. Culture of the Rumen Holotrich Ciliate Dasytricha ruminantium Schuberg
The successful cultivation of the anaerobic ciliate Dasytricha ruminantium is described. The cultures were established in a salts medium containing 30% clarified rumen fluid. Sucrose and extract of rumen holotrich protozoa were fed once daily for 2 to 4 hr, and Dasytricha was then transferred to medium free from these nutrients. Rumen fluid was essential. Om

9. The anomaly of silicon in plant biology.
Silicon is the second most abundant element in soils, the mineral substrate for most of the world's plant life. The soil water, or the "soil solution," contains silicon, mainly as silicic acid, H4SiO4, at 0.1-0.6 mM--concentrations on the order of those of potassium, calcium, and other major plant nutrients, and well in excess of those of phosphate. Silicon

10. Nutrients, Signals, and Photosynthate Release by Symbiotic Algae (The Impact of Taurine on the Dinoflagellate Alga Symbiodinium from the Sea Anemone Aiptasia pulchella).
Exogenous concentrations of 10 [mu]M to 1 mM of the nonprotein amino acid taurine stimulated photosynthate release from the dinoflagellate alga Symbiodinium, which had been freshly isolated from the sea anemone Aiptasia pulchella. Photosynthate release, as induced by taurine and animal extract, was metabolically equivalent at both concentrations in that they
