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 of Pinus radiata needles

Phytochemistry, 1978
Abstract Epicuticular wax isolated from the cotyledons and primary needles of 10-week-old Pinus radiata seedlings is similar in composition and contains 86% neutral compounds, viz. alkyl esters (25%, C 24 –C 64 ), nonacosan-10-ol (52%), heptacosane-5,10-diol (2%), nonacosane-4,10-diol, nonacosane-5,10-diol, and nonacosane-10,13-diol (total 12%) and

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.

Seed epicuticular wax of avena sativa

Phytochemistry, 1985
Abstract The main fractions in oat seed wax are β-diketones (15.5%), alkanols (14.4%), hydroxy-β-diketones (12.2%), esters (11.1%) and fatty esters (7.2%).

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,

Epicuticular waxes of two sorghum varieties

Phytochemistry, 1978
Abstract The epicuticular waxes of the two sorghum varieties Alliance A and SD 102 have been analyzed, after separation of the leaf blades from the sheaths. The major constituents were found to be free fatty acids but small amounts of esters, aldehydes, alcohols, n -alkanes and sterols were also detected. The typical chain lengths of aldehydes, free

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.

The maize epicuticular wax layer provides UV protection

Functional Plant Biology, 2003
As surface ultraviolet-B (UV-B) radiation levels increase due to the decline in the protective stratospheric ozone layer, ultraviolet radiation sunscreens will become more important for all plant species that grow in sunlight. Epicuticular waxes, which cover the aerial portions of all terrestrial plants, are ideally located to be sunscreens.

Ultrastructure and origin of epicuticular wax tubes

Journal of Ultrastructure Research, 1974
Coiled wax ribbons have been found intermingled among the long, thin tubes characteristic of some barley and wheat cuticles. An analysis of the structure of these wax ribbons and their relationship to the tubes has led to the following hypothesis to explain the origin of the broad spectrum of observed epicuticular wax structures.

Epicuticular wax composition of some European Sedum species

Phytochemistry, 1994
Epicuticular waxes from 30 species of Sedum and 2 species of Sempervivoideae, i.e. Aeonium spathulatum and Sempervivum nevadense, have been analysed by GC and GC-MS. The Sedum taxa examined were S. acre, S. album, S. series Alpestria (13 species), S. anglicum, S. brevifolium, S. litoreum, S. lydium, S.
