Biotic and abiotic stresses can alter the hormone balance and trigger the activation of pathways involved in the cotton stress responses, resulting in the abscission of squares, flowers and young bolls and consequent reductions in the seed cotton yield and fiber yield. As part of the mechanism that primarily regulates the protective response of plants against stresses, ethylene is considered a key hormone involved in this response, and increased ethylene synthesis has been observed when plants are subjected to stress. Thus, the development of strategies aimed to mitigate their negative effects can reduce the shed rate of reproductive structures and positively impact cotton productivity. For this purpose, 1-methylcyclopropene (1-MCP), a compound that... |

Diversos aspectos referentes à espécie-praga quarentenária Xiphinema americanum, incluindo características taxonômicas, distribuição geográfica, plantas hospedeiras, aspectos bioecológicos, potencial de transmissão de viroses e medidas de controle, entre outros, foram abordados nesta revisão. A dificuldade encontrada pelos especialistas na correta identificação deste nematóide quarentenário muitas vezes determina que X. americanum seja confundido com outras espécies pertencentes ao mesmo gênero. Esta praga, além de utilizar como hospedeiras várias espécies de plantas e encontrar-se estabelecida em diversas regiões do globo terrestre, constitui-se em um agente transmissor de viroses, dentre as quais algumas são também consideradas quarentenárias para vários... |

A broca-das-cucurbitáceas (Diaphania nitidalis) é uma praga de grande importância em diversas culturas, principalmente do pepineiro. Esta espécie pode apresentar preferência em relação a determinadas cultivares quanto à sua alimentação e até mesmo oviposição. Nesse sentido, o presente estudo objetivou avaliar a ocorrência desta praga em frutos de seis cultivares de pepineiro, em ambiente protegido. As cultivares Patton, Victoria, Premier, Vlaspik e Napoleon apresentaram, respectivamente, 50%, 43,75%, 37,50%, 34,37% e 25,87% dos frutos brocados. A cultivar Marinda apresentou resultado promissor, com apenas 10,37% dos frutos com presença de larvas de D. nitidalis. |

The objective of this work was to evaluate the carbon isotope fractionation as a phenomic facility for cotton selection in contrasting environments and to assess its relationship with yield components. The experiments were carried out in a randomized block design, with four replicates, in the municipalities of Santa Helena de Goiás (SHGO) and Montividiu (MONT), in the state of Goiás, Brazil. The analysis of carbon isotope discrimination (Δ) was performed in 15 breeding lines and three cultivars. Subsequently, the root growth kinetic and root system architecture from the selected genotypes were determined. In both locations, Δ analyses were suitable to discriminate cotton genotypes. There was a positive correlation between Δ and seed-cotton yield in SHGO,... |

ABSTRACT: The root system architecture (RSA) of plants and its functioning play a fundamental role in a number of plant growth mechanisms including water and nutrient uptake. Optimization of the RSA is important for stable and increased plant productivity under adverse conditions. Despite its great importance, studying the RSA is notoriously laborious because of the difficulty of accessing the rooting system of plants. We developed a root phenotyping platform, PhenoRoots, which allows for the non-invasive study of plant RSA. The system was built using inexpensive material and was designed to provide medium throughput. Substrate or soil-filled rhizotrons are used to grow plantlets, whose roots are directly visible through a glass plate. An experiment... |
