Abstract:
Weeds are host and multipliers of root-knot nematodes (Meloidogyne spp.). The status quo of the knowledge of the ability of Meloidogyne arenaria to reproduce in weeds is a little unknown. The present study aimed to evaluate the ability of M. arenaria to parasitize and reproduce in different weeds found in Brazil. Thirty-eight weed species were individually inoculated with 5000 eggs and second stage juveniles. Inoculated plants were kept in a greenhouse for 60 days. The design was completely randomized with twelve repetitions. The root system of each plant was evaluated for gall index, number of nematodes per root gram and reproduction factor. M. arenaria showed the ability to parasitize the 38 weed species. It was observed that 76.3% of the evaluated species were susceptible (RF???1.0) to M. arenaria. Oxalis corniculata resulted in the highest nematode RF (34.9). The present study identified for the first time the reproduction potential of M. arenaria on different weeds, showing their polyphagous habit, and indicating species of plants with greater ability to multiply this nematode that need more attention during the integrated management of this root-knot nematodes. |

Abstract:
Andropogon lateralis is a tall and highly plastic tussock-forming grass native from southern South America. It is a frequent component of Campos and Subtropical highland grasslands that often becomes dominant under lax grazing regimes. The aim of this work was to analyze the response of species diversity and forage production of a natural grassland dominated by A. lateralis to a wide range of grazing intensity. We hypothesized that species diversity and forage production would both peak at the intermediate canopy heights determined by grazing regimes of moderate intensity. A grazing experiment was conducted in a highland grassland with mesothermal humid climate at 922 masl (Atlantic Forest biome, Santa Catarina state, Brazil) that comprised 87 species from 20 families but had 50% of its standing biomass accounted by A. lateralis. Four pre-/post-grazing canopy heights?12/7, 20/12, 28/17, and 36/22 cm (measured on A. lateralis)?were arranged in a complete randomized block design with four replications, and intermittently stocked with beef heifers from October 2015 to October 2017. Andropogon lateralis cover decreased (from 75 to 50%), and species richness increased (15?25 species m?2) as canopy height decreased. Grazing intensity did not affect annual forage production (4.2 Mg DM ha?1). This natural grassland dominated by A. lateralis had a high capacity to adjust to grazing regimes of contrasting intensity, maintaining forage production stable over a wide range of canopy heights. However, to prevent losses in floristic diversity, such grassland should not be grazed at canopy heights higher than 28 cm MenosAbstract:
