Título:  Use of uniconazole in growth regulation and biochemical changes in maize.

Conteúdo:  ABSTRACT - The current paper evaluated the incubation time, and doses of Uniconazole (UCZ) applied to maize seeds to verify the plants? response at different phenological stages. MSG1001 hybrid seeds were treated with UCZ (0, 50, and 100 mg.kg-1 of seed) with different incubation times (IT ? 1 min and 12 h). In the lab experiment, the treated seeds were displaced in rolls of the previously moistened Germitest paper and incubated for a week in a BOD chamber at 25ºC with a 12-hour photoperiod. In the greenhouse experiments, sowing was carried out in pots with sand, and supplementary irrigation was applied for ten days. In the field experiment, sowing was performed with 0.5 m spacing between rows in densities of 75,000 and 65,000 plants.ha-1. In the BOD and the greenhouse, the design of both experiments was entirely randomized in a double-factor scheme (IT x UCZ). A randomized block design in a triple-factor scheme (IT x UCZ x Population) was used in the field experiment. Seed treatment with UCZ did not promote germination inhibition. The concentration of 100 mg UCZ kg-1 of seed in the 12-hour IT resulted in a more significant accumulation of root mass in seedlings after one week in the BOD. In the greenhouse, plants in the V1 stage presented longer shoot lengths for the treatments that received UCZ. Incubation time influenced root length, and IT = 12 h at a concentration of 50 mg UCZ kg-1 of seed was more efficient than IT = 1 min. Application of 100 mg UCZ kg-1 of seed was mo... Mostrar Tudo

Notas:  Título em português: Dinâmica de atributos microbiológicos do solo em sistemas integrados de produção, pastagem contínua e cerrado nativo.
Conteúdo:  The objective of this work was to evaluate the dynamics of soil microbiological attributes under integrated production systems, continuous pasture, and native cerrado. The study was conducted in a transition area from crop to livestock. Four areas with different land uses were evaluated: an integrated crop-livestockforestry system (ICLFS), cultivated with Eucalyptus urograndis alley cropping, spaced 2x2 m between plants and 22 m between alleys; an integrated crop-livestock system (ICLS); besides two adjacent areas of native cerrado and continuous pasture, used as a reference. For the assessment of microbiological attributes, soil samples were taken in the 0.00?0.10, 0.10?0.20, and 0.20?0.30-m layers, in February 2012 and February 2014 (rainy season), and in July 2012 and September 2013 (dry season). In general, soil under native cerrado had the highest microbial biomass carbon (MBC) levels, while under the ICLFS it had the lowest ones. The ICLS increased MBC and microbial coefficient in the deeper soil layers, after two years of establishment. Basal respiration, microbial biomass nitrogen, and MBC are the soil microbiological attributes better able to differentiate the evaluated systems.
