1. Cardinal temperatures and modeling of vegetative development in guava
RESUMO O objetivo deste estudo foi estimar as temperaturas cardinais (basal inferior, ótima e basal superior) e simular o desenvolvimento vegetativo da goiabeira através dos modelos filocrono (linear) e Wang e Engel (não linear) durante a fase de muda. Um experimento de campo instalado em Itajubá, MG (22° 24’ 46.43” S 45° 26’ 48.94” O) foi cond

2. Cardinal temperatures and thermal requirements for the initial development of two Brazilian native species
Resumo: O objetivo deste trabalho foi estimar as temperaturas cardinais e quantificar a necessidade térmica para o desenvolvimento inicial de mudas das espécies de árvores nativas Citharexylum myrianthum e Bixa orellana. O experimento foi realizado em campo, em delineamento inteiramente casualizado, em arranjo fatorial 2?12 (2 espécies arbóreas e 12 ép

3. MODELING DEVELOPMENT AND SOIL WATER BALANCE IN WHEAT / MODELAGEM DO DESENVOLVIMENTO E DO BALANÇO DE ÁGUA NO SOLO EM TRIGO
Wheat is the main winter crop in Rio Grande do Sul State. Temperature and photoperiod are the major environmental factors that control development in wheat. Wheat plants exposed to cold, non freezing temperatures induce them to enter the reproductive phase. Temperature and photoperiod response functions are used to simulate the wheat development. Development

4. CRESCIMENTO E DESENVOLVIMENTO DE GENÓTIPOS DE ARROZ (Oryza sativa L.) E DE BIÓTIPOS DE ARROZ VERMELHO (Oryza sativa L.). / Growth and development of cultivated Rice (Oryza sativa L.) genotypes and Red rice (Oryza sativa L.) biotypes.
Rice (Oryza sativa L.) constitutes the staple food of about half of the world`s population. Therefore, research on this crop has the potential of affecting the well being of a considerable number of people worldwide. Thermal time is a wide used method to tell time in plants, but this time concept is open to criticism. One of the goals of rice breeding progra

5. Biometria, germinaÃÃo e efeito do dÃficit hÃdrico no crescimento e trocas gasosas de Senna martiana (Benth.) Irwin &Barneby (Leguminosae-Caesalpinioideae)
Estudos ecofisiolÃgicos com espÃcies da regiÃo semi-Ãrida brasileira visam solucionar diversos problemas relacionados Ãs adaptaÃÃes morfolÃgicas, fisiolÃgicas e ecolÃgicas. A biometria, a germinaÃÃo e o efeito do dÃficit hÃdrico sobre o crescimento, trocas gasosas e potencial hÃdrico foliar de Senna martiana (Benth.) Irwin &Barneby, foram os o

6. EFFECT OF TEMPERATURE ON THE RATE OF GERMINATION IN BACILLUS CEREUS
Knaysi, Georges (Cornell University, Ithaca, N.Y.). Effect of temperature on the rate of germination in Bacillus cereus. J. Bacteriol. 87:619–622. 1964.—By use of the change of the spores from bright to dark, when observed in dark contrast with a phase microscope, as a criterion for the incipience (first stage) of germination, and increase in the volume

7. Heat Exchnage in the Black Skipjack, and the Blood-Gas Relationship of Warm-Bodied Fishes
The black skipjack, Euthynnus lineatus, uses a centrally located vascular heat exchanger to maintain core body temperatures warmer than ambient sea water. The heat exchanger is composed of the dorsal aorta, the posterior cardinal vein, and a large vertical rete. The dorsal aorta is embedded in the posterior cardinal vein and is completely bathed in venous bl

8. Temperature Characteristics of Photosynthetic and Heterotrophic Activities: Seasonal Variations in Temperate Microbial Plankton
The seasonal variation in temperature characteristics of photosynthetic and heterotrophic activities in the microbial plankton of Bedford Basin, Nova Scotia, was investigated. Measurements were made of the photosynthetic uptake of [14C]bicarbonate and its incorporation into cellular protein as well as the heterotrophic uptake of 3H-labeled amino acids and th
