1. CARACTERÍSTICAS MORFOGÊNICAS E ESTRUTURAIS DO SORGO FORRAGEIRO SUBMETIDO A LOTAÇÃO CONTÍNUA COM NOVILHOS DE CORTE SUPLEMENTADOS
Resumo A morfogênese é uma valiosa ferramenta para a compreensão da dinâmica do pasto, porém os estudos morfogênicos referentes à cultura do sorgo ainda são escassos. O objetivo do presente estudo foi avaliar os efeitos de diferentes níveis de suplementação sobre as características morfogênicas do sorgo forrageiro. O experimento foi conduzido na

2. CAPIM TROPICAL MANEJADO SOB LOTAÇÃO INTERMITENTE, SUBMETIDO A FONTES DE FÓSFORO COM DIFERENTES SOLUBILIDADES, ASSOCIADOS OU NÃO À ADUBAÇÃO COM NITROGÊNIO
Resumo Objetivou-se avaliar as características morfogênicas e estruturais do capim-piatã submetido à lotação intermitente e adubado com fontes de fósforo de diferentes solubilidades e adubação nitrogenada. Os tratamentos foram: controle (sem aplicação de adubo fosfatado); fonte de fósforo de lenta solubilidade (FNR); fonte de fósforo de rápida

3. Morphogenic, structural, productive and bromatological characteristics of Braquiária in silvopastoral system under nitrogen doses
ABSTRACT. This study aimed to evaluate the effect of different doses of nitrogen fertilization on the morphogenic, structural, productive and chemical composition of Urochloa decumbens (Stapf) R. D. Webster cv. Basilisk in a silvopastoral system with eucalyptus. The experimental treatments consisted of pastures of Basilisk cultivar, fertilized with 0, 100, 2

4. Comparative transcriptome profile of the leaf elongation zone of wild barley (Hordeum spontaneum) eibi1 mutant and its isogenic wild type
Abstract The naturally occurring wild barley mutant eibi1/hvabcg31 suffers from severe water loss due to the permeable leaf cuticle. Eibi1/HvABCG31 encodes a full ATP-binding cassette (ABC) transporter, HvABCG31, playing a role in cutin deposition in the elongation zone of growing barley leaves. The eibi1 allele has pleiotropic effects on the appearance of l

5. Productive and morphogenetic responses of buffel grass at different air temperatures and CO2 concentrations
The objective of the present trial was to evaluate the productive and morphogenetic characteristics of buffel grass subjected to different air temperatures and CO2 concentrations. Three cultivars of buffel grass (Biloela, Aridus and West Australian) were compared. Cultivars were grown in growth chambers at three temperatures (day/night): 26/20, 29/23, and 32

6. Forage productivity and morphogenesis of Axonopus aureus under different nitrogen fertilization rates
The effect of nitrogen (N) fertilization (0, 50, 100 and 200 kg N ha-1) on forage yield and morphogenesis of Axonopus aureus was evaluated in the savannas of Roraima State, Brazil. The experimental design was in randomized blocks with three replicates. The grass showed high responsiveness to N fertilization. Dry weight (DW) yield, morphogenetic and structura

7. Biomass flow in Tifton-85 bermudagrass canopy subjected to different management strategies under rotational grazing with dairy goats
Biomass flow characteristics and forage accumulation were evaluated in Bermudagrass (Tifton 85) pasture managed under intermittent stocking with different management strategies. The management levels utilized were conventional (10 cm residual height and unfertilized), light (20 cm residual height and unfertilized), moderate (20 cm residual height with fertil

8. Morphogenesis of native grasses of Pampa Biome under nitrogen fertilization
Morphogenetic and structural characteristics of the native grasses of the Pampa Biome Andropogon lateralis, Aristida laevis, Axonopus affinis, Erianthus angustifolius, Paspalum notatum, Paspalum plicatulum, Piptochaetium montevidense and Sorghastrum pellitum were evaluated as to the effect of nitrogen (N) fertilization (zero and 100 kg N/ha). The experimenta

9. Biomass flow in massai grass fertilized with nitrogen under intermittent stocking grazing with sheep
This study evaluated the biomass flow of massai grass in regrowth subjected to different nitrogen levels (control - no fertilization; 400; 800; and 1200 N kg ha-1year-1) and under rotational stocking with sheep, in a completely randomized design with repeated measures over time. The leaf elongation rate increased with increasing nitrogen levels (N) and the f

10. Morphogenetic and structural characteristics of guinea grass tillers at different ages under intermittent stocking
The objective of this research was to assess morphogenetic and structural characteristics of tillers of guinea grass cv. Tanzania at different ages. The pastures of guinea grass were managed in six pasture conditions related to the combination of three frequencies (90, 95, and 99% light interception) and two post-grazing heights (25 and 50 cm). In these six

11. Effects of biofertilizer rates on the structural, morphogenetic and productive characteristics of Piatã grass
The objective of this study was to investigate the influence of different levels of biofertilizers from cattle and swine manure on the structural, morphogenetic and productive characteristics of Brachiaria brizantha cv. Piatã. The experiment was arranged in a completely randomized factorial design with split plots. The plots were defined by eight treatments

12. Morphogenesis in guinea grass pastures under rotational grazing strategies
This study was conducted in order to evaluate the morphogenetic and structural characteristics of guinea grass cv. Mombasa under three post-grazing heights (intense - 30 cm, lenient - 50 cm and variable - 50 in spring-summer and 30 cm in autumn-winter) when sward light interception reached 95% during regrowth. Post-grazing heights were allocated to experimen
