Zinc oxide nanoparticles (ZnO-NPs) are known to be one of the multifunctional inorganic compounds which are widely used in everyday applications. This study aims to fabricate ZnO-NPs using grapefruit (Citrus paradisi) peel extract with particle size ranging from 12 to 72 nm. Structural, morphological, and optical properties of the synthesized nanoparticles have been characterized by using UV-Vi...

1. Indirect plant defences are well documented for the above-ground constituents of plants. Although less investigated to date, below-ground defences that mediate multitrophic interactions are equally important. Entomopathogenic nematodes (Steinernema diaprepesi) are attracted to herbivore-induced volatiles from Swingle var. (Citrus paradisi · Poncirus trifoliata) when fed upon by root weevil,D...

Granulation (also called crystallization or section drying) is a physiological disorder in citrus that results in reduced extractable juice and sometimes vesicle shriveling. While segments appear dry, the disorder is not caused by drying, but by gel formation within the vesicles. Though many citrus varieties may develop granulation (i.e., ‘Valencia’ orange, tangerines, and grapefruit), it was a...

The burrowing nematode, Radopholus similis, attacks agronomic and horticultural crops and many weeds, and is reported to reproduce on more than 250 plant species. Two races of R. similis are recognized. Although one race attacks citrus and the other race does not, they are morphologically similar. At present, the citrus race is found attacking citrus only in Florida, U.S.A., but it is known to ...

The biology of the citrus psyllid Diaphorina citri Kuwayama was studied at 258C on four commonly grown citrus and related plants [rough lemon, Citrus jambhiri Lush; sour orange, C. aurantiumL.; grapefruit,C.paradisiMacfadyen; andorange jessamine,Murrayapaniculata(L.) Jack] in the laboratory. The biological characteristics of each life stage are described. The average egg incubation periods on o...

the present study was done to investigate the correlation between biochemical changes of grafted tree fruits and rootstock fruits in gorgan university of agricultural science and natural resources in 2012-2013. for this purpose, the antioxidant activity and the total content of phenol and  flavonoid on four rootstocks such as yuzu (citrus junos), shelmahalleh (citrus sinensis var. shel mahalleh...

Plants have been used throughout human history for their medicinal properties and herbal medicines are popular worldwide. Since, all herbal medicines are mixtures of more than one active ingredient, such combinations of many substances obviously increase the likelihood of interactions taking place. Although herbal medicines have been used as remedies for number of illnesses, many of them have s...

Flying snake species (Chrysopelea) locomote through the air despite a lack of appendages or any obvious external morphological specialization for flight. Here photogrammetric techniques were used to investigate C. paradisi's aerial trajectory in three dimensions. Two videocameras arranged in stereo were used to record head, midpoint and vent landmarks on snakes that jumped from a horizontal bra...
