Porous Carbon Nanoparticles (PCNs) with well-developed microporosity were obtained from bio-waste oil palm leaves (OPL) using single step pyrolysis in nitrogen atmosphere at 500-600 °C in tube-furnace without any catalysis support. The key approach was using silica (SiO2) bodies of OPL as a template in the synthesis of microporous carbon nanoparticles with very small particle sizes of 35-85 nm ...
BACKGROUND There have been few studies on the sustainable use of non-timber forest products in arid and semi-arid zones. The palm Brahea dulcis has been one of the most important resources in semi-arid Mesoamerica, since pre-Hispanic times. Currently, some populations grow within protected natural areas, representing both a challenge and an opportunity for local development. This ethnoecologica...
Date palm is an important crop plant in the arid and semi-arid regions supporting human population in the Middle East and North Africa. These areas have been largely affected by drought and salinity due to insufficient rainfall and improper irrigation practices. Date palm is a relatively salt- and drought-tolerant plant and more recently efforts have been directed to identifying genes and pathw...
Leaves are the organs that intercept light and create photosynthesis. Efficient light interception is provided by leaves oriented orthogonal to most of the sun rays. Except in the polar regions, this means orthogonal to the direction of acceleration due to gravity, or simply horizontal. The leaves of almost all terrestrial plants grow in a gravity field that tends to bend them downward and ther...
The purpose of this study was to determine the effect swallow manure and Synechococcus sp. bacteria on morphophysiology oil palm plants in Pre Nursery. experiment used a factorial Randomized Block Design (RAK) three replication. first factor being compost, W0 = 0 grams/plant, W1 100 W2 150 W3 200 grams/plant. second concentration Bacteria, S1 10 ml/L, S2 15 S3 20 ml/L. Parameters observed were ...
In this study, a bioherbicide was produced by solid-state fermentation (SSF) using Diaporthe sp. Adjuvants were employed in a formulation to enhance the herbicidal activity towards the target (Cucumis sativus). The study was divided into two steps: (1) the fermentation condition for bioherbicide production was assessed; (2) evaluation of different formulations containing palm oil, Tween® 80 and...
Recent advances in oil-palm breeding and agronomic practices may have influenced the dry-matter production nutrient demand of tenera oil palm since last comprehensive studies published some three decades ago. This has raised concerns, updated knowledge requirements at various stages growth is essential for formulating fertilizer recommendations that meet agronomic, economic, environmental objec...
South Florida microfungi : a new species of Stanjehughesia ( hyphomycetes ) from Sabal palm Gregorio
Stanjehughesia floridensis anam. sp. nov. is described and illustrated from rachides and petioles of dead leaves of Sabal sp. in southeastern Florida, USA. The fungus is characterized by conidiophores reduced to monoblastic, brown, cylindrical, ampulliform or lageniform, solitary or clustered conidiogenous cells and obclavate to cylindric-obclavate, smooth, brown, 5-9 euseptate conidia with dar...
The insecticidal activity and residual effect of two formulations of lambdacyhalothrin were evaluated with Rhodnius prolixus; laboratory and field tests were conducted in the State of Chiapas, Mexico. The results indicate that the lethal concentrations of the active ingredient of SC (LC50 = 2.37 and LC90 = 8.5 mg, a.i./m2) were 4-8 times than those with the insecticide WP applied on R. prolixus...
