2. Genetic diversity and correlation network approach on cotton genotypes in southern of Minas Gerais
ABSTRACT The cultivation of Cotton (Gossypium hirsutum) is trending in an upward expansion at Minas Gerais state, Brazil. Due this growth, the breeding program has been demanded for the knowledge about the genetic diversity and correlation between morpho-agronomic traits, to start interesting crosses. The objective of this work was to study the genetic diver

3. Selection of cotton genotypes for yield and fiber quality under water stress
RESUMO O objetivo deste estudo foi selecionar linhagens de algodoeiro tolerantes ao estresse hídrico, com base em caracteres de produtividade e qualidade de fibra. O experimento foi conduzido em dois experimentos de campo em Quixeramobim - CE sem suplementação hídrica, nos anos: 2018 e 2019. Foram avaliados nove genótipos de algodoeiro, sendo seis linha

5. Multivariate classification of cotton cultivars tolerant to salt stress
RESUMO Dois métodos multivariados foram adotados para classificar genótipos de algodoeiro tolerantes ao sal com base no crescimento e nas características fisiológicas. Os genótipos foram cultivados em casa de vegetação e submetidos a 45 dias de irrigação com água salina, a partir da fase V4. A irrigação foi feita com água salina com CEa de 6,0 d

6. Otimização da extração de antocianinas presentes no feijão-preto e impregnação do extrato em matriz polimérica natural para uso como indicador de pH
OPTIMIZATION OF THE EXTRACTION OF ANTHOCYANINS PRESENT IN BLACK BEANS AND IMPREGNATION OF THE EXTRACT IN NATURAL POLYMERIC MATRIX FOR USE AS A pH INDICATOR. In this work, a method of extracting natural indicators, anthocyanins, present in black beans was optimized. The best extraction condition was obtained with 50 g of beans and 93 g of water, under agitati

7. Indications for accurate and appropriate use of personal protective equipment for healthcare professionals. A systematic review
ABSTRACT BACKGROUND: The speed of the spread of coronavirus disease 2019 (COVID-19) has put enormous pressure on hospitals and other healthcare facilities. This, together with blockages in several countries, has hindered the availability and accessibility of the necessary personal protective equipment (PPE). OBJECTIVE: To identify, systematically evaluat

8. Iron Nitrate Modified Cotton and Polyester Textile Fabric Applied for Reactive Dye Removal from Water Solution
In this work, we investigated the use of cotton scraps in natura and modified with iron nitrate, in the adsorption of one of the main water contaminants of the textile industries, the reactive black dye. Special attention was paid to the appropriate destination of the spent adsorbent, in compliance with the precepts of the circular economy. Cotton and polyes

9. Determining genetic diversity in cotton genotypes to improve variability
ABSTRACT A better understanding of genetic diversity in cotton cultivars is needed to make the most of the genetic resources and guarantee continuing improvements in the breeding programs. Our objective was to evaluate the genetic diversity among cotton genotypes from the top breeding programs in Brazil and recommend hybrid combinations that would increase v

10. Transcription factors and molecular markers revealed asymmetric contributions between allotetraploid Upland cotton and its two diploid ancestors
ABSTRACT Three Gossypium species have been used to breed cotton as they vary in their fiber production and resistance to stresses. Transcription factors (TFs) mostly are present in different copies or isoforms by which they conduct their regulation. Their copy number can determine organism behavior to a cue. Simple sequence repeats (SSRs) are one of the most

11. Comparative bio-efficacy of nuclear polyhedrosis virus (NPV) and Spinosad against American bollwormm, Helicoverpa armigera (Hubner)
ABSTRACT American bollworm (ABW), Helicoverpa armigera (Hubner), is considered as a major pest of cotton, Gossypium hirsutum, all over the globe. Due to its destructive feeding nature and continuous consumption of the same chemicals, it devolved resistant against many insecticides. Therefore, a combined application of bio- and synthetic-pesticide need to eva

12. PhenoRoots: an inexpensive non-invasive phenotyping system to assess the variability of the root system architecture
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 becaus
