A preservação ambiental é um tema constante da atualidade e assim, contribuir com a regeneração conservação fundamental para prover manter as condições adequadas à produção agropecuária. Deste modo, dentre ferramentas disponíveis auxiliar os produtores rurais quanto práticas agrícolas sustentáveis está adoção do uso dos bioinsumos em suas propriedades. Portanto, fim de entender fatores que impulsionam agricultores adotar o bioinsumos, este estudo coletou dados 53 grãos região Cerrado...
Exposure to nickel (Ni) at high concentrations can lead production of reactive oxygen species (ROS) resulting in oxidative damage the cellular level. We investigated antioxidative responses Nicotiana tabacum cv BY-2 cell suspension Ni stress (0.075 and 0.75 mM NiCl2) over a 72 h period with special attention potential alterations isoenzymes superoxide dismutase (SOD), catalase (CAT) glutathione reductase (GR). Two main SOD were observed, Mn-SOD (band I) Fe-SOD II), as well one CAT isoenzyme...
The vinasse is a by-product generated during the manufacture of alcohol from sugarcane fermentation. Rich in organic matter, it known that has potential to be used as source nutrients for plants well microorganisms. In this study, fungi Pleurotus sajor-caju, P. ostreatus, albidus and flabellatus were cultivated utilised complementary diet Danio rerio fish. mycelia cultured 15 days lyophilised offered fishes at rate 2% (medium/body weight) 28 days. produced highest biomass (16.27 g L−1)....
The aim of this study was to evaluate the performance enzymatic hydrolysis acid or alkali pretreated sugarcane bagasse for production fermentable sugars. first step consisted selection commercial enzymes presenting highest cellulolytic activities. After four enzymes: HPL, CL, P1 and P4, their performances were tested in with alkali. sugar content hydrolysates analyzed by anion exchange liquid chromatography. Data showed that joint action 0.5% pretreatment, 121ºC, 30 minutes enzyme CL...
Sustainable agricultural practices aim to improve soil quality, promote biodiversity, preserve the water cycle, capture carbon, and welfare of rural-workers an-imals, while producing foods with profitability. However, little is known about conditions motivations that lead farmers know, adopt implement these sustainable practices, such as, for example, use bioinputs. Thus, objective this study was qualitatively analyze perceptions grain Brazilian Cerrado regarding bioinputs on their...
Abstract Barley (Hordeum vulgare L.) has had an important impact on human nutrition. Hull-less barley is a genetically improved type that been widely used in recent years. Six Brazilian hull-less varieties (IAC-IBON 214-82; IAC 8612-421; 8501-31; 8501-12; IAPAR 39-ACUMAI; 8501-22) were analyzed for storage protein constituents, amino acid contents, and similarity among the varieties. Albumins, globulins, prolamins I II, glutelins extracted separated by SDS-PAGE. The total contents of flour...
Lysine is an essential amino acid normally present in very low concentration cereal seeds. In previous reports we have studied the metabolism of lysine several distinct high-lysine maize mutants and observed drastic variations activity saccharopine dehydrogenase (SDH), a key enzyme involved degradation. We now analyzed SDH using non-denaturing polyacrylamide gel electrophoresis (PAGE) to identify possible isoenzymes that could explain patterns previously observed. The results indicated...

Laranjeiras 'Pêra' enxertadas em 11 cultivares ou híbridos de tangerineiras foram plantadas 1988 Itirapina (SP), num Latossolo Vermelho-Amarelo textura arenosa, no espaçamento 4,25m x 7,5m e conduzidas sem irrigação sob clima Cwa. Tristeza declínio são endêmicos na região. As 'África do Sul', 'Xienkhouanga', 'Empress', 'Cleópatra', 'Wildt', 117.477 'Sul da África', diferirem entre si, induziram, ordem decrescente, as maiores produções frutos às laranjeiras 'Pêra', total das quatro primeiras...
Uptake of nutrients and cadmium (Cd) are dependent upon many factors, including plant species, ions concentration pH. Tolerance to Cd-induced oxidative stress can be modulated by phytohormones such as abscisic acid (ABA), which induce the production reactive oxygen activating proteins enzymes involved in response possibly tolerance. The present study aimed evaluate biochemical variations induced Cd ABA-deficient sitiens tomato mutant (sit) its wild-type counterpart, Micro-Tom (MT), grown at...
