Recuperação de área degradada por construção de hidroelétrica com adubação verde e corretivo Soil reclamation by green manure and soil ammendements in areas degraded by hydroelectric power plant construction

Revista Brasileira de Ciência do Solo, 2008
As "áreas de empréstimo" em hidrelétricas são as áreas remanescentes da construção da fundação da barragem e podem ser consideradas áreas degradadas, pois delas foram retirados os horizontes superficiais do solo.

Use of natural ensiling additives with tropical grasses: Physicochemical properties, in vitro fermentation characteristics, and microbial community diversity indices

JSFA reports, EarlyView.
Abstract Background Improving feed quality, availability, and cost‐effectiveness is a big challenge for livestock to ensure animal‐derived food for nutritional security. The aim of the study was to find out how some natural ensiling additives affect physicochemical properties, proximate composition, microbial population, in vitro fermentation ...

Novel tetronamides derived from mucobromic acid: synthesis, structural elucidation, DFT calculations and phytotoxic activity

Pest Management Science, EarlyView.
The acyclic mucobromic acid, activated by (1S)‐(+)‐10‐camphorsulfonic acid, afforded the chiral compound 1b, precursor for aza‐Michael addition/elimination on the butenolide yielding tetronamides 2b‐7b. Their relative SRSR configuration was confirmed by the spectrometric methods, DFT calculation and statistical methods.

New Considerations on Meiosis, Affinity and Genomic Constitution in Aneuploids and Interploid Hybrids of Urochloa P. Beauv. (Brachiaria)

Plant Breeding, EarlyView.
ABSTRACT The combination of polyploidy, apomixis and the formation of aneuploid and interploid hybrids makes the genus Urochloa an interesting system for investigating meiotic stability and genome behaviour in grasses. In this study, routine meiotic analysis and genomic in situ hybridization (GISH) were used to (i) evaluate meiosis in three hybrids of ...
