Short-term exposure to silicon rapidly enhances plant resistance to herbivory.
Abstract:Silicon (Si) can adversely affect insect herbivores, particularly in plants that evolved the ability to accumulate large quantities of Si. Very rapid herbivore-induced accumulation of Si has recently been demonstrated, but the level of protection against herbivory this affords plants remains unknown. Brachypodium distachyon, a model Si hyperaccumulating grass, was exposed to the chewing herbivore, Helicoverpa armigera, and grown under three conditions:supplied Si over 34 d (+Si), not supplied Si (-Si), or supplied Si once herbivory began (-Si +Si).
Libido and serving skills of Zebu cattle Bulls. [Libido e habilidade física em touros zebuínos.]
Abstract:The goal of this study was to evaluate the rejection rates of Zebu bulls during behavioral assessment (libido and serving ability) and the importance of this step in bull breeding soundness evaluation (BBSE). A total of 1,534 bulls reared in the state of Rio Grande do Sul, Brazil, of Nelore (1,340), Brahman (76), Guzerá (98), and Tabapuã (210) breeds were evaluated. The evaluation consisted of four steps.
The drop plate method as an alternative for Azospirillum spp viable cell enumeration within the consensus protocol of the REDCAI network. (Brief report). [La técnica de la microgota como alternativa para el recuento de Azospirillum spp. dentro del protocolo de la Red de Control de Calidad de Inoculantes (REDCAI).]
ABSTRACT - Quality evaluation of commercial inoculants is essential to warrant an adequate crop response to inoculation within a biosecurity framework. In this sense, this work is aimed at standardizing and validating the drop plate method for the enumeration of Azospirillum viable cells as an alternative to the spread plate technique, which is currently proposed in the consensus protocol of the REDCAI network. Between 14 and 25 private and public laboratories participated in three independent trials.
