Micromorphology of epicuticular waxes in Centrosperms

Plant Systematics and Evolution, 1988
Epidermal surfaces of about 500 species from some 250 genera of centrospermous families plus some possibly related families were examined by scanning electron microscopy. The micromorphology of their epicuticular waxes is described under taxonomic aspects. In general, Centrosperms tend to develop wax platelets on their cuticle.

Photodegradation of Fenitrothion and Parathion in Tomato Epicuticular Waxes

Journal of Agricultural and Food Chemistry, 2005
Photodegradation of (14)C-labeled fenitrothion ([O,O-dimethyl O-(3-methyl-4-nitrophenyl) phosphorothioate]) and parathion ([O,O-diethyl O-(4-nitrophenyl) phosphorothioate]) was conducted on a series of solid surfaces including isolated tomato fruit and leaf cuticle waxes.

Leaf epicuticular waxes.

Science (New York, N.Y.), 1969
The external surface of the higher plants comprises a cuticular layer covered by a waxy deposit. This deposit is believed to play a major part in such phenomena as the water balance of plants and the behavior of agricultural sprays. The wax contains a wide range of organic compounds.

Effect of Epicuticular Waxes of Fruits on the Photodegradation of Fenthion

Journal of Agricultural and Food Chemistry, 1997
After treatment lipophilic pesticides tend to diffuse by penetrating the epicuticular wax of fruits. In this way, solar radiation only acts on pesticide molecules after passing through the waxes. The effect of epicuticular waxes of three fruits (orange, nectarine, and olive) on the photodegradation of fenthion was studied.

Epicuticular wax variation in ecotypes of Arabidopsis thaliana

Phytochemistry, 1997
Quantification of the epicuticular wax from the stems of 40 ecotypes of Arabidopsis thaliana showed a two-fold range in total wax load that was not correlated to known abiotic characteristics of the ecotype's origin of collection. Chemical analysis of these ecotypes revealed similar epicuticular wax profiles for all ecotypes except CT-1.

Evidence for Surfactant Solubilization of Plant Epicuticular Wax

Journal of Agricultural and Food Chemistry, 2001
The solubilization of isolated, reconstituted tomato (Lycopersicon esculentum Mill.) fruit and broccoli (Brassica oleracaea var. botrytis L.) leaf epicuticular waxes (ECW) by nonionic octylphenoxypolyethoxy ethanol surfactant (Triton X-100) was demonstrated in a model system by TLC and fluorescence analysis using pyrene as a fluorescent probe.

Chemical Composition of Oat Seed Epicuticular Wax

Journal of the Science of Food and Agriculture, 1983
AbstractThe analysis of the main components present in Avena sativa seed epicuticular wax is reported, using a simplified chemical procedure. The main components are esters (21.1%), hydrocarbons (15.5%) and free acids (14.1%).

Epicuticular Wax and Cuticular Resistance in Rice

Physiologia Plantarum, 1979
AbstractHigh leaf cuticular resistance has been reported as a component adaptation of plants to drought prone regions, Experiments were conducted to evaluate and characterize the role of epicuticular wax as a component of cuticular resistance to water vapor loss from rice (Oryza sativa L.) leaves.

Epicuticular wax of four species of Chionochloa

Phytochemistry, 1983
Abstract Shoot epicuticular wax of four species of Chionochloa contained esters (21–38 %); alkanes (15–29%); aldehydes (4–13%); alcohols (8–16%) and acids (1–5%). The major carbon chain lengths ranged from C 24 to C 32 in the acids, alcohols and aldehydes and C 29 and/or C 31 in the alkanes.

Triterpenoids in Epicuticular Waxes

1989
All aerial organs of higher plants are covered primarily with a thin continuous wax layer. These surface or epicuticular waxes consist of a very complex mixture of different components. In most cases these very long chained lipids are found in form of homologous series.
