PSII Activity Was Inhibited at Flowering Stage with Developing Black Bracts of Oat [PDF]
International Journal of Molecular Sciences, 2021 The color of bracts generally turns yellow or black from green during cereal grain development. However, the impact of these phenotypic changes on photosynthetic physiology during black bract formation remains unclear. Two oat cultivars (Avena sativa L.), ‘Triple Crown’ and ‘Qinghai 444’, with yellow and black bracts, respectively, were found to both ...

Structural characterization of allomelanin from black oat [PDF]
Phytochemistry, 2016 The brown to black coloration found in plants is due to the melanins, which have been relatively poorly investigated among the plant pigments. The aim of this work was to study the dark pigment extracted from the black oat hull with respect to composition and structure.

Physical properties of soils and soybean yields after planting cover crops [PDF]
Engenharia Agrícola, 2015 Cover crops are important for improving soil quality. However, soil properties usually have some spatial dependence. Thus, this study aimed to evaluate the effect of winter cover crops on physical properties of soil and soybean yields using thematic maps.

Performance of soybean grown in succession to black oat and wheat [PDF]
Pesquisa Agropecuária Brasileira, 2020 Abstract: The objective of this work was to evaluate the influence of isolated or combined roots and straw of black oat and wheat, as previous crops in autumn/winter, on the performance of soybean in succession. The experiment was carried out in the 2017/2018 and 2018/2019 crop seasons in a randomized complete block design, with four replicates.

Times and methods of black oat management on corn plantability
Revista Ceres, 2022 ABSTRACT The importance of maintaining straw on the soil surface is a subject widely discussed and proven in the literature. However, the effects of this straw on planting efficiency and quality still lack information. In this sense, both time and method of the black oat management influence the permanence of the straw on the soil and, thus, can ...

Temperature changes in soil covered by black oat straw [PDF]
Pesquisa Agropecuária Brasileira, 2017 Abstract: The objective of this work was to evaluate the effect of different amounts of black oat (Avena strigosa) straw covering soil surface on soil temperature at different depths. The treatments consisted of 0, 3, 6, and 9 Mg ha-1 straw. Soil temperature was measured hourly by a thermocouple inserted at different depths (0, 5, 15, 30, and 50 cm ...
