Electrical Properties of Roystonea regia Fruit Extract as Dye Sensitized Solar Cells [PDF]

, 2014
Utilizing solar energy in producing electricity can minimize environmental pollution generated by fossil fuel in producing electricity. Our research was base on the extraction of dye from Roystonea regia fruit by using methanol as solvent. The dye extracts were used as sensitizers in Dye-sensitized solar cell (DSSCs).

Thermodynamic characterization of the palm tree Roystonea regia peroxidase stability [PDF]

Biochimie, 2008
The structural stability of a peroxidase, a dimeric protein from royal palm tree (Roystonea regia) leaves, has been characterized by high-sensitivity differential scanning calorimetry, circular dichroism, steady-state tryptophan fluorescence and analytical ultracentifugation under different solvent conditions. It is shown that the thermal and chemical (

EFFECTS OF THE TEMPERATURE AND MATURATION STAGES ON THE GERMINATION OF ROYSTONEA REGIA SEEDS

Acta Horticulturae, 2013
Roystonea regia (Kunth) O.F. Cook is largely used as ornamental. The propagation is done almost exclusively by seeds; however, there is a great variation in the germination process influenced by many factors. The objective of this work was to study the effects of the temperature and maturation stages on the germination of R. regia seeds.

Allergic evaluation of Roystonea regia (Kunth.) O. F. Cook. among Keralites, India. [PDF]

Annals of Plant Sciences, 2018
Aerobiological studies conducted in Kerala (India), revealed the incidence of pollen grains of Roystonea regia (Kunth.) O.F.Cook. belonging to the family Aracaceae as a common airborne pollen member. Previous clinical studies conducted in different parts of the world also proved its allergic potentiality among human beings. Present study concerned with

Preliminary characterization of palmiche flour (Roystonea regia) for food use [PDF]

Palmiche is an abundant food in Cuba, promising due to its high oil and protein content, with levels varying between different varieties of its species. This study aimed to characterize palmiche flour for food use preliminarily. Fresh fruits of royal palm (Roystonea regia) were used, and their size, weight, and hardness were determined, the latter ...

Positive relationships among aboveground biomass, tree species diversity, and urban greening management in tropical coastal city of Haikou. [PDF]

Ecol Evol, 2021
We investigated the relationship between tree species diversity and aboveground biomass using multiple regression, which revealed significant relationships across all five types of land uses. Aboveground biomass in green spaces was also correlated with anthropogenic factors, especially time since urban development, or site age, annual maintenance ...

Why do understorey <i>Licuala</i> palm fruits turn from red to white and then black when ripe? [PDF]

Ecol Evol
We record the changes in colour, sugar content, reflectance and predation of the fruits of a tropical understorey palm, Licuala ferruginea, as they ripen. Based on these signatures, we posit that the fruits are likely dispersed by birds such as forest bulbuls, and are predated upon but ineffectually dispersed by edge forest mammal species such as wild ...

Pest categorisation of Diaprepes abbreviatus

EFSA Journal, Volume 21, Issue 11, November 2023., 2023
Abstract The EFSA Panel on Plant Health performed a pest categorisation of the citrus root weevil Diaprepes abbreviatus (L.) (Coleoptera: Curculionidae) for the European Union (EU) following the commodity risk assessment of Ligustrum delavayanum topiary grafted on L. japonicum plants from the UK in which D.
