Method for maize plants counting and crop evaluation based on multispectral images analysis. The processing of multispectral images acquired with embedded cameras in unmanned aerial vehicles (drones) has brought new opportunities for precision agriculture. In this study a method for evaluatin... ... Repository: BDPA Publication year: 2024
A method for counting and classifying aphids using computer vision. Aphids are insects that attack crops and cause damage directly, by consuming the sap of plants, and indirectly,by vectoring microorganisms that can cause diseases. Cereal crops are hosts for many aphi... ... Repository: BDPA Publication year: 2020
May the crossing between diploid and tetraploid Italian ryegrass transfer glyphosate resistance to the next generation? Italian ryegrass (Lolium multiflorum Lam.) is a grass weed found in winter cereals, with several glyphosate-resistant diploid populations. Furthermore, the use of Italian ryegrass tetraploid genotypes... ... Repository: BDPA Publication year: 2020
Chromosome duplication in Lolium multiflorum Lam. Artificial chromosome duplication of diploid genotypes of Lolium multiflorum (2n=2x=14) is worthy to breeding, and aims to increase the expression of traits with agronomic interest. The purpose of thi... ... Repository: BDPA Publication year: 2014
MASTREE+: Time-series of plant reproductive effort from six continents. Significant gaps remain in understanding the response of plant reproduction to environmental change. This is partly because measuring reproduction in long-lived plants requires direct observation over... ... Repository: BDPA Publication year: 2022
Electropenetrographic comparison of feeding behavior of dichelops furcatus (Hemiptera: Heteroptera: Pentatomidae) on soybean and spring cereals . We used electropenetrography to quantify and compare counts and durations of selected waveforms, produced by adult females of the stink bug Dichelops furcatus (F.). Insects fed on immature soybean pod... ... Repository: BDPA Publication year: 2020
Brazilian ornamental phytogenetic resources in Embrapa germplasm banks: obstacles and opportunities. Brazilian floriculture is driven by novelties, requiring the constant entry of new products into the market. This situation favors Brazil, which has, in its native flora, unique species in the world a... ... Repository: BDPA Publication year: 2022
Stability in chromosome number and DNA content in synthetic tetraploids of Lolium multiflorum after two generations of selection. ABSTRACT - Chromosome doubling of Italian ryegrass genotypes ( Lolium multiflorum Lam.) adapted to the brazilian edaphoclimatic conditions is an important strategy used by breeders and aims to obtain... ...

Nonparametric indexes in selecting advanced potato clones. This study aimed to test nonparametric selection indexes for selection of advanced potato clones and identification of those that are likely to become cultivars. The experiments were carried out in 20... ... Repository: BDPA Publication year: 2022
