Abstract

IIIMudança climática e seus efeitos na cultura do arroz RESUMO A partir da revolução industrial, houve um aumento da emissão de gases de efeito estufa na atmosfera terrestre, como o dióxido de carbono (CO

Untargeted Metabolomics of Nicotiana tabacum Grown in United States and India Characterizes the Association of Plant Metabolomes With Natural Climate and Geography

“…To date, environmental changes have been reported to highly influence the sensitivity of plants to environments and plant productivity (Aggarwal, 2008; Ahmad et al, 2010; Walter et al, 2010; Gosling et al, 2011). Furthermore, numerous studies have particularly reported that global climate change can highly affect agricultural productivity and crop yield (Walter et al, 2010; Gosling et al, 2011; Bowen and Friel, 2012; Dwivedi et al, 2013). Most of this type of research has focused on single climate factors, such as temperature in a controlled condition or a specific local environment.…”

Selection of Interpolators to Predict Populations of Tibraca limbativentris in Irrigated Rice

“…However, the values of the standard deviation of the errors and mean square root of the errors indicate that there is a smaller variation of these with respect to the mean for the ordinary kriging interpolator, which stands out its greater accuracy with respect to the inverse of distance weighted interpolator. -----------------------------------V3 ----------------------------------- ------------------------------------R4 -----------------------------------a 0.373 (1) -----------------------------------R6 ----------------------------------- ------------------------------------V3 ----------------------------------- -----------------------------------V6 ----------------------------------- -----------------------------------V9(R0) ----------------------------------- -----------------------------------R4 ----------------------------------- -----------------------------------R6 ----------------------------------- -----------------------------------R9 ----------------------------------- The maps of the spatial distribution of adults of T. limbativentris per m² interpolated respectively by ordinary kriging and inverse of distance weighted for different crop stages revealed a better delimitation of the zones with population densities for the ordinary kriging interpolator. Where the lines presented an organic behavior, different from that found for the interpolator of the inverse of distance weighted, with straight lines (Figure 1a, b).…”

“…Rice (Oryza sativa L.) is one of the most produced and consumed cereals in the world, being the main food for more than half the world population [1]. Brazil is the ninth producer, accounting for approximately 2% of production, with Rio Grande do Sul state being the state of greatest production, with about one million cultivated hectares corresponding to 60% of total national production [2].…”

Effect of elevated CO2on initial growth and gas exchang of yellow melon

“…Já Walter et al 2010, descreve que o efeito benéfico do CO2 poderá ser anulado pelo efeito negativo das altas temperaturas nos cultivos de arroz. Ruiz-Vera et al (2013) determinaram que o aquecimento inverteu o esperado estímulo da fotossíntese e da produtividade de soja advindo do incremento de CO2.…”
