It has long been held that the low photosynthetic rates (A) of coffee leaves are largely associated with diffusive constraints to photosynthesis. However, relative limitations stomata and mesophyll overall diffusional photosynthesis, as well coordination leaf hydraulics limitations, remain be fully elucidated in coffee. Whether actual A under ambient CO2 concentrations is kinetic properties Rubisco high (photo)respiration also remains elusive. Here, we provide a holistic analysis understand...
Blast, caused by Pyricularia oryzae, has become an economically important disease in wheat Brazil, but little effort been devoted to understanding the wheat-P. oryzae interaction. This study was intended determine effects of P. infection on photosynthetic process plants using a susceptible (BR 18) and partially resistant cultivar (BRS 229). It found that net carbon assimilation rate (A), stomatal conductance (gs), transpiration were dramatically reduced both cultivars due lesser degree BRS...
The selection of wheat genotypes according to their drought tolerance is essential off-season cultivation. objective this work was characterize through yield and components, morphological characteristics under water stress, irrigated use efficiency in the Cerrado region Brazil. Genotypes were planted during winters 2016 2017 since there no precipitation season levels can be measured. They then submitted four regimes: WR1, WR2, WR3, WR4, representing 100 %, 83 50 30 % evapotranspiration...
The shade leaves of coffee (Coffea arabica L.) apparently retain a robust photosynthetic machinery that is comparable to sun and can fix CO2 at high rates when subjected light intensities. This raises the question why plant would construct such despite low achieved by supply. Here, we grew plants 100% or 10% full sunlight demonstrated exhibited faster induction compared with their counterparts, in parallel lower loss states under dim light, were well protected against short-term sudden...
Considerando o efeito positivo do silício (Si) na melhoria desempenho fisiológico de várias espécies plantas quando infectadas por patógenos, este trabalho teve como meta investigar desse elemento capacidade fotossintética e no metabolismo antioxidativo dos cultivares algodoeiro NuOpal BRS Buriti, supridas ou não com Si, durante processo infeccioso Ramularia areola. A infecção R. areola afetou negativamente a taxa líquida fixação CO2 (A), condutância estomática (g s), transpiração razão...
Abstract: The objective of this work was to evaluate the influence soil remineralizer fine-graded mica schist (FMS) on soybean (Glycine max) physiology, yield, and grain quality under different water regimes (WRs) in Brazilian Cerrado. experiment conducted field conditions for two years, using four WRs three treatments: schist, conventional fertilization, control. In 2017 2018, following were evaluated: WR1, WR2, WR3, WR4, corresponding a mean value 100, 65, 44, 28% crop evapotranspiration...
Selecting drought-tolerant and more water-efficient wheat genotypes is a research priority, spe-cifically in regions with irregular rainfall or areas where climate change expected to result reduced water availability. The objective of this work was use high-throughput measurements morphophysiological traits characterize relation stress. Field experiments were conducted from May September 2018 2019, using sprinkler bar irriga-tion system control availability eighteen genotypes: BRS 254; 264;...
No presente projeto identificou-se com o penetrômetro de Stolf diferentes níveis compactação solo e foi avaliado impacto da ação antrópica nos atributos físicos do por meio comparação entre áreas vegetação nativa nas quais é praticada a atividade agrícola. Para tal foram avaliadas quatro características condição e/ou utilização solo. Posteriormente essas avaliações à coleta análise dos dados propostas soluções medidas para amenizar os efeitos negativos das atividades empregadas testadas
Abstract Evapotranspiration (ET) is one of the most important processes in hydrologic cycle, constituting main responsible for water losses at surface. Several evapotranspiration models use information from surface temperature and vegetation indices captured by remote sensors such as MODIS LANDSAT to estimate ETc value. The objective this study apply SSEBop model soybean a field experiment under four regimes, using high-resolution multispectral thermal images collected remotely piloted...

O sorgo [Sorghum bicolor (L.) Moench] é uma planta de origem africana, da mesma família do milho. tipo sacarino utilizado como matéria prima para bionergia (etanol) e apresenta elevada eficiência no uso água. Este trabalho teve objetivo caracterizar cultivares quanto às características fisiológicas em diferentes intensidades irrigação, analisar trocas gasosas fluorescência clorofila a fim subsidiar programas melhoramento genético direcionados à obtenção genótipos produtivos situações déficit...
In order to practice sustainable and resource-efficient agriculture, the use of new technologies such as water-retaining polymers is essential. The objective this study was evaluate effect a polymer incorporated into soil on gas exchange yield under different water regimes (WR) in three soybean cultivars. experiment conducted at Embrapa Cerrados field conditions 2016 2017, using cultivars (BRS 5980IPRO, NA 5909RG BRS 7280RR). Soybean were submitted four (representing 30%, 50%, 83% 100%...
O Brasil possui a segunda maior populacao canina e felina do mundo, menor somente que os dos Estados Unidos da America. Associado ao elevado numero de animais emergem importantes problemas prejuizos socioambientais como o aumento abandonados, disseminacao doencas carater zoonotico, agressoes por mordedura, poluicao ambiental, sonora, predacao selvagens danos com acidentes automobilisticos, quais afetam diretamente saude publica pais. Um exemplo preocupante raiva, no ano 2000 totalizou 23...
