1. Combining abilities analysis for ear rot resistance in popcorn hybrids development
ABSTRACT Ear rot caused by fungi of genus Fusarium (FER) is one of the potentially harmful diseases to grain quality in maize. Given the capacity to produce mycotoxins, FER presents a risk to food safety. This study sought to identify parents and indicate hybrids of popcorn with a higher level of resistance to the incidence and severity of FER. Hybrids were

2. Moringa water extract promising additive to prolong the activity of baculovirus under field-sunlight conditions in Egypt
Resumo Os baculovírus são considerados como biopesticidas eficazes, exceto por não estarem ativos sob condições de luz solar. O objetivo deste estudo é avaliar a capacidade do extrato de moringa para prolongar a atividade do vírus sob condições de campo egípcias, tendo em vista que Moringa provou ser um material protetor forte sob investigação an

3. Abscisic acid and ethephon treatments applied to ‘Verdejo’ white grapes affect the quality of wine in different ways
ABSTRACT: Exogenous ethephon and abscisic acid (ABA) treatments are used worldwide to improve the coloring of red table grapes, but there is little information about their impact on the quality of white grapes and wines. The aim of this work was to evaluate the effects of exogenous ethephon and ABA applications at veraison on the composition of ‘Verdejo’

4. The influence of topdressing nitrogen on Azospirillum spp. inoculation in maize crops through meta-analysis
ABSTRACT The Azospirillum is considered one of the most studied plant growth promoter genus. These bacteria are capable of promoting plant growth through several factors. However, the effect of Azospirillum spp. associated to nitrogen fertilization on maize grain yield has brought about controversial results. Thus, the objective of this study was to verify t

5. Enhancing the Supercapacitive and Superparamagnetic Performances of Iron Oxide Nanoparticles through Yttrium Cations Electro-chemical Doping
A one-pot electrosynthesis platform is reported for fabrication of Y3+ doped iron oxide nanoparticles (Y-IONPs). In this procedure, Y-IONPs are electro-deposited from an additive-free aqueous solution of iron(III) nitrate, iron(II) chloride and yttrium chloride. The analysis data provided by X-ray diffraction (XRD), field emission electron microscopy (FE-SEM

6. Cacao families and parents selected as resistant to natural infection of Moniliophthora perniciosa
Abstract The known sources of resistance to witches' broom (WB), a severe disease of cacao, are limited. Aiming to identify families and parents resistant to Moniliophthora perniciosa, a population of 22 families was evaluated by assessing the number of brooms formed per tree during 10 years under field conditions. The population was established in randomize

7. Genetic variation for growth and selection in adult plants of Eucalyptus badjensis
Abstract The aim of this study was to evaluate Eucalyptus badjensis concerning the genetic variation for growth traits and the potential of the species in supporting a breeding programme. The field trial was a provenance/progeny test established in Campina da Alegria, Santa Catarina, Brazil (latitude 26°52′05.1″ S, longitude 51°48′47.5″ W, altitude

8. Urea decreases specific ion effects on the LCST of PMMA-block-PDMAEMA aggregates
Urea is a well-known additive used as a mild protein denaturant. The effect of urea on proteins, micellar systems and other colloids is still under debate. In particular, urea has shown interesting effects on the ion binding in systems like charged micelles, vesicles or Langmuir-Blodgett films. The urea effect on polymeric aggregates in water is still an ope

9. Assessment of som (Persea bombycina) clones for resistance against Phyllosticta persae
Som (Persea bombycina) is an economically important tree used as food source by the muga silkworm, Antheraea assamensis. Phyllactinia leaf spot (PLS), caused by Phyllosticta persae, affects all som cultivars during June to September (rainy season) and is responsible for foliage losses up to 26%. Information about the effect of this disease at the farmer leve

10. Seasonality and chemical elicitation of defense oleoresin production in field-grown slash pine under subtropical climate
Oleoresin is a key defense strategy of advanced gymnosperms, based on the combination of a complex anatomical structure of resin ducts and elaborate terpene biochemistry. Given the vast array of oleoresin economic applications in the chemical, pharmaceutical, agrochemical, and biofuel industries, translating factors that regulate terpene biosynthesis into hi

11. Estudo de misturas asfálticas mornas em revestimentos de pavimentos para redução de emissão de poluentes e de consumo energético. / Study of warm mixes asphalt as a pavement surface for reducing polluants emissions and energy consumption.
In the last years there has been an increasing concern for the environment. In this context, warm mixes asphalt was developed with positive impact not only on the environmental pollution, but also on the energy consumption, due to the reduction of mixing and compaction temperatures. This work compares the behavior of warm mixes asphalts (with surfactant addi

12. Genetic control of the angular leaf spot reaction in common bean leaves and pods
Information about genetic control of plant reaction to pathogens is essential in plant breeding programs focusing resistance. This study aimed to obtain information about genetic control of the angular leaf spot reaction in leaves and pods from common bean (Phaseolus vulgaris L.) line ESAL 686. This line was crossed with cultivars Jalo EEP 558 (resistant), C
