1. Interspecific hybrids between Paspalum plicatulum and P. oteroi: a key tool for forage breeding
ABSTRACT Grama-tio-pedro (Paspalum oteroi Swallen) is a rare stoloniferous grass of the Plicatula group of Paspalum, well adapted to continuous grazing in areas subject to seasonal flooding in the Pantanal region, in central western Brazil. The species is a facultative apomictic (asexual reproduction by seed) tetraploid, sporadically cultivated on Pantanal f

2. Yield-scaled global warming potential of two irrigation management systems in a highly productive rice system
ABSTRACT Water management impacts both methane (CH4) and nitrous oxide (N2O) emissions from rice paddy fields. Although controlled irrigation is one of the most important tools for reducing CH4emission in rice production systems it can also increase N2O emissions and reduce crop yields. Over three years, CH4 and N2O emissions were measured in a rice field in

3. Caracterização morfológica, fisiológica e bioquímica da Corticeira-do-banhado em condições de alagamento / Caracterização morfológica, fisiológica e bioquímica da Corticeira-do-banhado em condições de alagamento / Morphological, physiological and biochemical caracterization of Corticeira-do-banhado in flooding conditions / Morphological, physiological and biochemical caracterization of Corticeira-do-banhado in flooding conditions
The Erythrina crista-galli L., popularly known as corticeira-do-banhado, is a medium sized tree belonging to family Fabaceae, known especially for their vibrant colored flowers. The cork is listed as a plant immune to the court, by CONAMA, such is the devastation of their habitat and due to its importance in the restoration of riparian vegetation and restora

4. Manejo de agua e de fertilizante potassico na cultura de arroz irrigado.
O manejo da agua de irrigacao e as doses e epocas de aplicacao de fertilizantes tornam-se aspectos de extrema importancia no exito do aproveitamento das varzeas para o cultivo de arroz (Oryza sativa L.) irrigado ou este seguido de outras especies. Com o objetivo de comparar distintas formas de manejo de agua e de fertilizante potassico no comportamento do ar

5. Flooding tolerance of tomato genotypes during vegetative and reproductive stages
A greenhouse experiment was conducted to investigate the effect of flooding on two tomato cultivars and two wild related species. Forty days old tomato plants were subjected to a continuous flooding stress of different durations: 0, 2, 4 and 8 days. Plant pots were placed inside larger plastic pots; they were irrigated with excessive quantity of tap water at

6. INTERMITTENT AND CONTINUOS FLOODING IN RICE: WATER USE, AGRONOMIC EFFICIENCY AND IMAZETHAPYR, IMAZAPIC AND FIPRONIL DISSIPATION / IRRIGAÇÃO CONTÍNUA E INTERMITENTE EM ARROZ IRRIGADO: USO DE ÁGUA, EFICIÊNCIA AGRONÔMICA E DISSIPAÇÃO DE IMAZETHAPYR, IMAZAPIC E FIPRONIL
Every anthropogenic activity causes environmental impact in some extent. Rice paddy fields area are pointed out as an activity with high potential of pollution due to the large amount of water used to maintain the flooding and the intensive use of pesticides and nutrients that can be transported to the environment. Though, there are other irrigation manageme

7. Soil quality of cultivated and native pastures systems in the Nhecolandia sub-region, South Pantanal Wetlands. / Qualidade do solo em sistemas de pastagens cultivada e nativa na sub-regiÃo da NhecolÃndia, Pantanal Sul Mato-Grossense
The Pantanal is one of the planetâs largest continuous wetlands areas and where fauna and flora of outstanding beauty and abundance develops. Favored by the richness of natural resources, beef cattle raising, conducted in extensive raising systems, constitutes the chief economic activity. However, the search for yield increases and greater competitivity of

8. INTERACTION OF RICE-FISH CULTURE WITH PESTICIDES AND EFFECT ON ZOOPLANKTON COMMUNITY / INTERAÇÃO DA RIZIPISCICULTURA COM AGROQUÍMICOS E EFEITOS SOBRE A COMUNIDADE ZOOPLANCTÔNICA
The objective of this experiment was to determine the lethal concentration (LC50;96h) of azimsulfuron (A) and metsulfuron-methyl (M) herbicides and carbofuran (C) insecticide for common (Cyprinus carpio), grass (Ctenopharyngodon idella )and big head (Aristichthys nobilis) carps fingerlings, and the effect of these pesticides on the cholinergics response in f

9. An Ethylene-Mediated Increase in Sensitivity to Auxin Induces Adventitious Root Formation in Flooded Rumex palustris Sm.
The hormonal regulation of adventitious root formation induced by flooding of the root system was investigated in the wetland species Rumex palustris Sm. Adventitious root development at the base of the shoot is an important adaptation to flooded conditions and takes place soon after the onset of flooding. Decreases in either endogenous auxin or ethylene con
