Impacts of climatic changes on the vegetative development of olive cultivars
Provedor de dados: 91
Autores: Florêncio,Gabriel W. L.; Martins,Fabrina B.; Ferreira,Mábele de C.; Pereira,Rodolfo A. de A.
ABSTRACT The aim of this study was to simulate the vegetative development of the olive cultivars Arbequina and MGS ASC315 cultivated in Maria da Fé, MG, Brazil (22° 18’ 29” S, 45° 22’ 31” W, 1.276 m of altitude). The development of these cultivars was simulated in nine transplanting dates, considering three distinct scenarios for three periods (2011-2040, 2041-2070 and 2071-2100). Climate changes influence the olive crop management. The increase in air temperature modifies the development rate and the duration of the seedling phase of the cultivars Arbequina and MGSASC315. In colder months, there is accelerated vegetative development and shorter seedling phase duration. Conversely, in warmer months, there is delayed development with longer seedling phase...

Análise de distribuição de chuva para Santa Maria, RS
Provedor de dados: 91
Autores: Silva,Joel C. da; Heldwein,Arno B.; Martins,Fabrina B.; Trentin,Gustavo; Grimm,Edenir L.
O estudo em pauta teve como objetivo analisar a distribuição da quantidade diária de precipitação e do número de dias com chuva e determinar a variação da probabilidade de ocorrência de precipitação diária, durante os meses do ano, em Santa Maria, RS. Os dados de precipitação utilizados foram obtidos durante 36 anos de observação, na Estação Climatológica do 8º Distrito de Meteorologia, localizada na Universidade Federal de Santa Maria (29º 43' 23" de latitude Sul e 53º 43' 15" de longitude Oeste, altitude 95 m). Analisaram-se as seguintes funções de distribuição de probabilidade: gama, Weibull, normal, log-normal e exponencial. As funções que melhor descreveram a distribuição das probabilidades foram gama e Weibull. O maior número de dias com chuva...

Impacts of climate projections on water balance and implications on olive crop in Minas Gerais
Provedor de dados: 91
Autores: Santos,Diego F. dos; Martins,Fabrina B.; Torres,Roger R.
ABSTRACT Minas Gerais is vulnerable to climate change, with negative impacts on water balance and changes in the cultivation of several crops. Currently, the olive crop has been an alternative source for farmers, especially those in the South of the state. However, there is no information on areas with climatic conditions suitable for olive cultivation, as well as the possible impacts of climate change. The aim of this study was to verify the impact of climate projections on water balance and agroclimatic zoning for olive cultivation in the Minas Gerais, based on current climate conditions (1980-2011), and different climate change projections for three future periods (2011-2040, 2041-2070 and 2071-2100). For the current climate, Minas Gerais showed 37% of...

Cardinal temperatures and modeling of vegetative development in guava
Provedor de dados: 91
Autores: Ferreira,Mábele de C.; Martins,Fabrina B.; Florêncio,Gabriel W. L.; Pasin,Liliana A. A. P.
ABSTRACT The aim of this study was to estimate cardinal temperatures (base, optimum, and maximum), and simulate the vegetative development of guava crop through phyllochron (linear) and Wang and Engel (nonlinear) models at the seedling phase. The experiment was conducted in Itajubá, MG, Brazil (22° 24’ 46.43” S 45° 26’ 48.94” W), for two years in a completely randomized design with twelve sowing dates and five experimental units per treatment, totaling sixty experimental units. The cardinal temperatures were estimated using twelve methods described in the literature and the values were: base, 10.9 °C, optimum, 17.3 °C and maximum, 51.2 °C. The phyllochron model was superior to Wang and Engel’s model for simulation of vegetative growth of guava, with root...
