Epicuticular wax of Agropyron intermedium

Phytochemistry, 1976
Abstract Wax on leaves of Agropyron intermedium contains hydrocarbons (11%, C27–C33), esters (11%, C32–C60), free alcohols (180%, C26) 25-oxohentriacontane-14,16-dione (17%), 10-oxohentriacontane-14,16-dione (5y%), 25-hydroxyhentriacontane-14,16-dione (12%) and 26-hydroxyhentriacontane-14,16-dione (2%).

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.

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.

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 Eragrostis curvula

Phytochemistry, 1982
Abstract Epicuticular wax of Eragrostis curvula contains hydrocarbons (6%), esters (13%), acids (3%), alkanols (4%), tritriacontane-12,14-dione (47%), 5(S)-5-hydroxytritriacontane-12,14-dione (14%) as major components. The esters consist of triterpenol esters (42%) as well as alkanol esters. The free alkanols consist principally Of C16C32 components,
