Application of geographic information system for mapping of Hevea brasiliensis and Aquilaria malaccensis land suitability at Simpang Kuta Buluh

IOP Conference Series: Earth and Environment, 2020
Hevea brasiliensis and Aquilaria malaccensis were planted by the community because of its high economic value. The suitabilty land of Hevea brasiliensis and Aquilaria malaccensis in North Sumatra Province are important, especially in the agroforestry ...

Latex yield variation among Hevea brasiliensis clones grown under the agro- climate of South-West Ethiopia

Trees, Forests and People, 2022
Hevea brasiliensis is the primary commercial source of natural rubber in the world and its latex is a source for many industrial inputs. The latex yield potential of rubber tree plantations has been lower than the estimated potential due to latex yield ...

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

Runoff and Sediment Response to Different Fire Intensities in a Hyrcanian Mixed Broadleaved Forest Ecosystem

Land Degradation &Development, EarlyView.
ABSTRACT Wildfires are increasingly recognized as a critical driver of ecosystem degradation, with post‐fire hydrological and soil impacts posing significant threats to biodiversity, water quality, and long‐term land productivity. In fire‐prone regions, understanding how varying fire intensities exacerbate runoff and erosion is essential for guiding ...

Enhancing Hydrophobicity of EPR‐Based Rubber Compounds via Fumed Silica and Sulfur/Peroxide Curing Systems

Journal of Vinyl and Additive Technology, EarlyView.
The Effect of Silica and Curing Systems on the Hydrophobicity of EPR‐Based Rubber Compounds. ABSTRACT In this study, the dual effect of fumed silica and conventional curing systems such as peroxide and sulfur on the hydrophobicity of ethylene‐propylene‐based rubber (EPR) compounds has been examined.

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 ...

A divide-and-conquer approach for genomic prediction in rubber tree using machine learning

Scientific Reports, 2022
Rubber tree (Hevea brasiliensis) is the main feedstock for commercial rubber; however, its long vegetative cycle has hindered the development of more productive varieties via breeding programs. With the availability of H.

In vitro culture method of powdery mildew (Oidium heveae Steinmann) of Hevea brasiliensis [PDF]

AFRICAN JOURNAL OF BIOTECHNOLOGY, 2012
A method for culturing powdery mildew (Oidium heveae) from isolated leaves of Hevea brasiliensis was evaluated, which included three steps: Leaves and fungi selection, nutrient solution and culture dish  preparation, fungi inoculation and culture. The culture time and produced conidia number were considered as decision index. We tested the influence of

Balancing bioenergy expansion and restoration: Global shifts in biodiversity intactness

Journal of Applied Ecology, EarlyView.
While restoration is the best strategy for biodiversity, planting energy crops on agricultural land rather than replacing natural vegetation could minimise losses in biodiversity intactness index. However, achieving targets for bioenergy, climate change and restoration will require strategic land‐use planning to minimise ecological compromises ...

Investigations on the nutritional status of Hevea brasiliensis plantations in the humid forest zone of CameroonPart 2: Establishment of macro nutrient norms

Journal für Kulturpflanzen, 2013
Standard nutrient values are needed for the assessment of optimum nutrient concentrations for improved and sustained yields. The aim of this study was to establish optimum soil and plant nutrient values for Hevea brasiliensis in the humid forest region ...
