13. Storage of cuttings before and after grafting influences survival and vigor of vine grafts
ABSTRACT Several grafting methods have been developed, and bench grafting with stratification is the most widely used technique, except in Brazil, which is still in adaptation. The objective of this study was to evaluate for how long plant material can be stored before the grafting and the optimum temperature for stratification. Cultivar 'Paulsen 1103' was u

14. PERSPECTIVAS DE MERCADO E DESAFIOS DA PRODUÇÃO DO ÁCIDO ITACÔNICO A PARTIR DE BIOMASSA
Itaconic acid (IA) is a very promising platform molecule due to the possibility of it being used to obtain products such as methyl methacrylate and synthetic latex, with the prospect that its global market will grow at an average annual rate of 2.8% (CAGR) from 2021 to 2026, exceeding US$ 116.6 million in sales. The main technological route used to obtain it

17. Geochemical assessment of platinum group metals for phytomining
Abstract Phytomining is suggested as a technology to obtain platinum group metals (PGMs) nanoparticles from plants grown on the mineralized soils or tailings. Samples from North American Palladium (Canada) and gossans from Broken Hill (BH) (Australia) were studied to assess the possibility of using these PGM-rich samples as substrates for phytomining. The bi

18. Evaluation yield and genetically factors in different cultivars of gladiolus
Abstract In order to suggest the best cultivars of gladiolus to grow in moderate regions of Iran, an experiment was carried out in a complete randomized block design in three replications with five cultivars of Gladiolus grandiflorus (‘Oscar’, ‘Red Advance’, ‘White Prosperity’, ‘Rose Supreme’ and ‘Lemon Drop’) at the ornamental plants res

19. Colonization-related functional traits of plants in a 50-hectare plot of secondary tropical forest
ABSTRACT The growth-survival trade-off hypothesis states that functional traits of stem, wood, leaves and fruits govern acquisitive and conservative strategies of plant species that grow/survive differently in forests. We aimed to determine whether heterogeneity during the colonization of a secondary Atlantic Forest fragment causes differences in colonizatio

20. Recent Developments on the Elucidation of Colloidal Aspects of Asphaltenes and Their Relevance to Oilfield Problems
Asphaltenes constitute the heavy petroleum fraction responsible for deposition events that may lead to reduced oil production, therefore of great interest for flow assurance. These molecules self-assemble in solutions leading to formation of aggregates that eventually grow towards precipitation and blockages in reservoirs and pipelines. Based on the Yen-Mull

21. Cultivable bacterial diversity associated with bromeliad roots from ironstone outcrops in central Brazil
Resumo Estudos sobre a diversidade bacteriana associada a plantas silvestres são raros, especialmente naqueles que crescem em associação com bromélias. No presente estudo, isolamos e identificamos bactérias epífitas e endofíticas das raízes das bromélias Dyckia excelsa, D. leptostachya e Deuterocohnia meziana ocorrentes nas “cangas” no Pantanal

22. 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

23. Genome-Wide Assessment of Putative Superoxide Dismutases in Unicellular and Filamentous Cyanobacteria
Abstract Cyanobacteria are photoautotrophic prokaryotes capable to grow in diverse ecological habitats, originated 2.5-3.5 billion years ago and were first to produce oxygen. Since then superoxide dismutases (SOD) acquired great significance due to their ability to catalyze detoxification of byproducts of oxygenic photosynthesis i.e. superoxide radicals. In

24. Evaluation of Argentinean medicinal plants and isolation of their bioactive compounds as an alternative for the control of postharvest fruits phytopathogenic fungi
Abstract One of the main problems that fruit health goes through in recent years is the difficult eradication of their fungal pathogens after harvesting. This concern to the whole world because it represents huge losses of production, fruit export restrictions and consumers distrust. One of the alternatives to solve this problem could be the exploration of p
