1. Distant populations of a Xanthosoma (Araceae) species have different floral scents but the same cyclocephaline beetle pollinators
ABSTRACT We report on the reproductive biology, pollinators, and thermogenesis of the widely distributed Araceae species, Xanthosoma striatipes. We analyzed the floral scent in one population and compared it to a previous study. Xanthosoma striatipes was studied at three sites in Brazil, São Paulo, Minas Gerais and Maranhão. The results showed constancy of

2. Late defoliation of ‘Chardonnay’ grapevine in subtropical highland climate
ABSTRACT Chardonnay cultivar has shown great potential of planting and development in sites above 900m of Brazilian southeast for sparkling wines production. The quality of this product is related to vineyard climate and management, since both affect the vine development and grape composition. In this study, three defoliation orientations (east, west and eas

3. Meta-topolin: an alternative for the prevention of oxidative stress in sugarcane micropropagation
RESUMO A influência de duas citocininas aromáticas (CKs), 6-benzilaminopurina (BAP) e meta-topolina (mT) na propagação in vitro e no metabolismo redox da cana-de-açúcar (Saccharum spp., variedade RB98710) foi investigada. As plantas foram cultivadas em meio Murashige e Skoog (MS) suplementado com mT (5 µmol.L-1) ou BAP (5 ou 6,66 µmol.L-1) por 40 dia

5. NMR-Based Metabolomic Screening for Metabolites Associated with Resistance to Meloidogyne javanica in Annona muricata Roots
The resistance of Annona muricata roots to the nematode Meloidogyne javanica was investigated by nuclear magnetic resonance (NMR)-based metabolomics in combination with principal component analysis (PCA). Metabolic changes in roots exposed and not exposed to the nematode were evaluated and compared. In addition, the presence of nematicidal compounds in the r

7. MODELING OF BASIL ESSENTIAL OIL EXTRACTION WITH VARIABLE DIFFUSION COEFFICIENT
ABSTRACT: Essential oils are complex mixtures of volatile compounds found at low levels in aromatic plant specific parts. Soluble in organic solvents, these oils are characterized by their fragrance and antimicrobial activity, being widely used in industries. The mathematical modeling of essential oil extraction is a relevant step in the project of industria

8. Revestimentos de alta camada obtidos com a modificação de resinas epóxi novolaca pela reação com organo-siloxano e catálise ácida
Epoxy resins are an important class of thermostable polymers, widely used in structural applications or as adhesives. However, the low fracture resistance is their main weakness in many applications. Due to this fact, this study aims to modify a polymer matrix based on a novolac epoxy resin with an organo siloxane (AMS). The final properties of cured epoxys

9. Rupture of glandular trichomes in Ocimum gratissimum leaves influences the content of essential oil during the drying method
Medicinal and aromatic plants are commonly sold dried; however, it is necessary to understand the effects different drying methods have on these materials, to ensure their efficiency and quality. Ocimum gratissimum L., Lamiaceae, is an aromatic plant whose essential oil is stored in glandular trichomes. This study aimed to confirm the effects of different dr

10. Eichhornia crassipes: an advantageous source of shikimic acid
The water hyacinth (Eichhornia crassipes (Mart.) Solms, Pontederiaceae) is considered as one of the most productive plants on earth, and an aquatic weed, which causes serious environmental problems. In this study, this species is presented as an alternative of a renewable source of shikimic acid. Although this acid is an important intermediate in the biosynt

11. Feeding strategies to design the fatty acid profile of sheep milk and cheese
The majority of sheep milk produced in the world is transformed into cheese. Feeding is a major factor affecting the quality of sheep milk and, therefore, of sheep cheese. Because fat is the main compound of cheese, this review gives an update on the effects of feeding and nutrition on milk fat content and deeply discusses feeding strategies aimed at increas

12. Light intensity on growth, leaf micromorphology and essential oil production of Ocimum gratissimum
Light conditions can promote the growth and development of plants and contribute to increase the essential oil production of commercially cultivated medicinal and aromatic species. In view of the great importance of Ocimum gratissimum L., Lamiaceae, as an aromatic plant, the objective of this work was to determine the effect of light intensities (approximate
