Genetic diversity of cultivated accessions and wild species of rubber tree using EST‑SSR markers

Pesquisa Agropecuária Brasileira, 2012
The objective of this work was to evaluate the efficiency of EST‑SSR markers in the assessment of the genetic diversity of rubber tree genotypes (Hevea brasiliensis) and to verify the transferability of these markers for wild species of Hevea. Forty‑five

Post‐Additional Proteins into Rubber Matrices Behave as Filler to Reinforce Rubber

Macromolecular Materials and Engineering, EarlyView.
The post‐additional proteins exhibit a reinforcement effect regardless of the origin of the rubber. The proteins are lyophilized to obtain a powder, which is then incorporated into the rubber matrices using a solution‐mixing process. These findings suggest that protein can function as a reinforcing filler depending on the rubber preparation process ...

Latex Serum‐Derived Supramolecular Networks Enable Toughening of Natural Rubber

Macromolecular Rapid Communications, EarlyView.
Latex‐serum addition enhances strain‐induced crystallization (SIC) toughening in natural rubber, increasing tearing strength and extending the SIC activation window. Supramolecular networks form via bifurcated hydrogen bonding between polyol components (e.g., quebrachitol) and end‐functionalized polyisoprene chains, serving as effective crystallization

Nutrient content and redistribution in leaves of Hevea brasiliensis and Pinus oocarpa /
Concentração e redistribuição de nutrientes em folhas de Hevea brasiliensis e Pinus oocarpa

Semina: Ciências Agrárias, 2000
The content of macronutrients (N, P, K, Ca, Mg, and S) and nutrient redistribution were evaluated in leaves of two species, an 8 years old angiosperm (Hevea brasiliensis) and a 25 years old a gymnosperm (Pinus oocarpa), both cultivated on an eutrophic ...

Piezoresistive Natural Rubber Composites: A Comparison Between Low‐Temperature Glutaraldehyde Curing Agents and Conventional Sulfur Curing Systems

Polymer Composites, EarlyView.
The secondary electrical signal peak during cyclic experiment observed in S‐cured NR sensors was eliminated with GA curing due to the homogeneous distribution of crosslink points in the GA‐cured NR network. ABSTRACT This study examines the piezoresistive behavior of natural rubber (NR) composites cured with sulfur (S) and glutaraldehyde (GA) and ...

Connecting tradition and technology: The digitization of the ethnobotanical collection at the Rio de Janeiro Botanical Garden

PLANTS, PEOPLE, PLANET, EarlyView.
The digitization of RBetno (JBRJ) represents a step forward for biodiversity conservation in Brazil. Aligned with the Kunming‐Montreal Global Biodiversity Framework (Target 2, 2020–2030), this project documents the use of plants, including traditional knowledge and vernacular names, with a focus on the Atlantic Forest and Amazon.
