Yield, Yield Components, Soil Chemical Properties, Plant Physiology, and Phosphorus Use Efficiency in Soybean Genotypes
(Communications In Soil Science And Plant Analysis, 2017-01-01) [Artigo]
Expansion of soybean [Glycine max (L.) Merrill] cultivated in Brazil to regions with low fertility soils gave rise to studies on the possibility of obtaining highly productive cultivars with high nutrient use efficiency. ...
Discovering the giant nest architecture of grass-cutting ants, Atta capiguara (Hymenoptera, Formicidae)
(Insects, 2017-06-01) [Artigo]
Atta capiguara is a grass-cutting ant species frequently found in Cerrado biome. However, little is known about the giant nest architecture of this ant. In this study, we investigated the architecture of three A. capiguara ...
Critical Periods of Storage of the Greenhouse Gases in Polypropylene Syringe
(Communications in Soil Science and Plant Analysis, 2017-08-06) [Artigo]
It is convenient to store gas samples containing e.g. carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), in polypropylene syringes before chromatographic analysis. However, there is no study of the integrity of ...
Estimativa de parâmetros genéticos para caracteres silviculturais e densidade do lenho em teste de progênies de Eucalyptus urophylla
(Scientia Forestalis/Forest Sciences, 2017-03-01) [Artigo]
In eucalypt species, progeny tests of open pollinated trees are usually used for selecting superior genotypes in genetic improvement programs. In this study, genetic parameters were estimated in a progeny test of Eucalyptus ...
Soil dynamic alterations and use efficiency of nitrogen by Brachiaria species
(Australian Journal of Crop Science, 2017-01-01) [Artigo]
Under certain circumstances species of the Brachiaria genus, particularly B. humidicola might be able to suppress the biological nitrification in soil. This study aimed to investigate the ability of four Brachiaria species ...
Fusarium oxysporum causing wilt in Eustoma grandiflorum in Brazil
(Summa Phytopathologica, 2017-07-01) [Nota]
Longevity of Arachis pintoi cv. BRS Mandobi seeds stored under different conditions
(Journal Of Seed Science, 2017-07-01) [Artigo]
The goal of this work was to evaluate the storage effects under different temperatures, relative humidities (RH) and packaging types on the seed physiological quality and pod moisture content of Arachis pintoi cv. BRS ...
Pre-infection stages of Austropuccinia psidii in the epidermis of eucalyptus hybrid leaves with different resistance levels
(Forests, 2017-10-17) [Artigo]
Rust is a major Eucalyptus spp. disease, which is especially damaging for early-stage plants. The aim of this study was to verify the pre-infection process of Austropuccinia psidii (A. psidii) in the leaves of three ...
Allogrooming, self-grooming, and touching behavior: Contamination routes of leaf-cutting ant workers using a fat-soluble tracer dye
(Insects, 2017-06-09) [Artigo]
The aim of this study was to determine whether worker self-grooming, allogrooming, and direct contact promotes the dispersal of substances among members of the colony. For this purpose, a tracer (Sudan III dye) was applied ...
Deep rooting of rainfed and irrigated orange trees in Brazil
(Trees-structure And Function, 2017-02-01) [Artigo]
Fine roots of orange trees reached a depth of approx. 6 m in a sandy tropical soil. Root area index was more responsive to irrigation than leaf area index. Although the crucial role of deep rooting on the hydraulic functioning ...
