Studies on plant cuticular waxes-IV

Phytochemistry, 1968
Abstract Statistical analyses of the results of gas chromatographic studies of the alkane components of Cupressus leaf waxes show that individual trees and species have highly characteristic minor alkane patterns. Species may be diagnosed by such analyses and hybrids have alkane patterns intermediate between the parent species.

In situ assembly of cuticular wax

Planta, 1976
Cytochemical reactions within the primary cuticle (cutinised layer) indicate that the lamellae are formed from polar lipids. The electron microscope shows that the lamellae are involved in wax formation and it is suggested that the polar lipids provide in situ precursors for the synthesis of cuticular wax.

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.

Esters of Picea abies needle cuticular wax

Phytochemistry, 1995
Abstract A new class of wax ester has been isolated from the needle cuticular wax of Picea abies . Identification of 2-methyl-but-1-en-4-yl triacontanoate, -dotriacontanoate, -tetratriacontanoate and -hexatriacontanoate was carried out by gas chromatography, mass spectroscopy, 1 H NMR and chemcial studies.

Sealing Plant Surfaces: Cuticular Wax Formation by Epidermal Cells

Annual Review of Plant Biology, 2008
The vital importance of plant surface wax in protecting tissue from environmental stresses is reflected in the huge commitment of epidermal cells to cuticle formation. During cuticle deposition, a massive flux of lipids occurs from the sites of lipid synthesis in the plastid and the endoplasmic reticulum to the plant surface.

An investigation of sugar‐cane cuticular wax

Journal of the Science of Food and Agriculture, 1957
AbstractThe saponified cuticular wax from sugar cane (N.Co 310 variety) was found to consist of an acid fraction (containing some triene‐unsaturated acids), small amounts of hydrocarbons in the C27–C31 range, and of lower and higher molecular weight substances made up of aliphatic alcohols (of which n‐octacosanol was identified as the main component ...

Composition of Cuticular Waxes on Osmunda regalis Fronds

Journal of Chemical Ecology, 2000
The chemical composition of rodlet-shaped wax crystals on fronds of Osmunda regalis was analyzed. In all, 139 compounds belonging to 14 homologous series were detected in the surface extract. They included typical plant wax constituents: alkanes (C25–C33), alkyl esters (C38–C50), primary alcohols (C22–C32), secondary alcohols (C27 and C29), ketones ...

Unusual alkanes pattern of some plant cuticular waxes

Collection of Czechoslovak Chemical Communications, 1991
Eight gas chromatograms present an unusual composition of alkanes ( including branched alkanes) from cuticular waxes. In plants of a lower phylogenetic class (liverwort, lichens), further in seeds and sprouts of tubers (Solanaceae) and especially in the anthers and pollens of some plants a high proportion of branched alkanes has been found (up to 72%).

Long-chain alkanediols from Myricaria germanica leaf cuticular waxes

Phytochemistry, 2000
In the leaf cuticular waxes of Myricaria germanica L. four different series of alkanediols were identified: (1) hentriacontanediol isomers with one functional group in the 12-position and a second group in positions ranging from 2 to 18, (2) C30-C34 alkanediols carrying one hydroxyl function on a primary and one on a secondary carbon atom.

Assessing the cuticular wax composition of black cottonwood

2021
Poplars (Populus spp.) are among the most productive tree species in the northern hemisphere, displaying fast-growth across a wide geoclimatic range. Climate change and alterations in precipitation regimes can affect the distribution of forest trees and poplars are one of the most sensitive woody plants to water stress due to their naturally high ...
