1. BIOMECHANICAL PROPERTIES OF WOLFBERRY PLANT ORGANS
ABSTRACT To improve the picking rate and reduce the wrong picking rate of the existing wolfberry harvesting machinery, in this study, the binding force and physical appearance of the immature fruit stalk, mature fruit stalk, flower, and leaf were studied to guide the designing of new-generation wolfberry harvesting machinery and lay theoretical foundation fo

2. 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

3. 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

4. Phenology and agronomic components of first and second-cycle strawberry
RESUMO Em busca de maior retorno econômico após o transplantio das mudas, muitos produtores de morango têm feito o cultivo por dois ciclos consecutivos. No entanto, há necessidade de estimar o desenvolvimento fenológico e avaliar o potencial agronômico do morangueiro nesse sistema. O objetivo deste trabalho foi comparar a necessidade térmica, a taxa d

5. 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

6. 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

7. Phyllochron and leaf appearance rate in oat
Abstract Phyllochron and leaf appearance rate are both important parameters in the production efficiency of agricultural crops. The objectives of this study were to determine the phyllochron and leaf appearance rate in 4 oat cultivars (Avena sativa L.) in 3 sowing dates and verify the variability of phyllochron and leaf appearance rate among cultivars and so

8. 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

9. 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

10. Effect of water stress on the growth of Arachis pintoi plants under different nitrogen levels
The objective was to evaluate the growth of Arachis pintoi fertilized with nitrogen and water deficiency conditions. The study was developed in a 4 × 4 factorial arrangement with four nitrogen levels (0, 40, 80 and 120 kg N/ha) and four irrigation levels (25, 50, 75 and 100% of field capacity), in a completely randomized experimental design, with four repli

11. The chlorophyll a fluorescence as an indicator of the temperature stress in the leaves of Prunus persica
Plants growing in temperate regions are often exposed to stress conditions caused by high temperatures. Photosynthesis is one of the metabolic processes most sensitive to high temperature stress, and it is often inhibited before other cellular functions. Using peach leaf disks, we studied the transient chlorophyll a fluorescence along with the gas exchanges

12. 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
