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.

Composition of epicuticular waxes of some grasses

Canadian Journal of Botany, 1977
The compositions of the epicuticular waxes of grasses Agropyron desertorum, Bromus inermis, Elymus cinereus, Elymus junceus, Festuca ovina, and Phleum pratense have been determined. Hexacosanol was the principal component of wax of A. desertorum and P. pratense, and octacosanol, of wax of E.

Composition of Epicuticular Wax on Isocoma Leaves

Botanical Gazette, 1987
Isocoma coronopifolia and I. drumondii incorporated 14CO2 into epicuticular waxes in which free fatty acids and free fatty alcohols constituted 85%-90% of the total wax. Alkane (

Composition of Epicuticular Wax on Opuntia engelmannii

Botanical Gazette, 1990
Alkanes and esthers contributed up to 97% of the total epicuticular wax on cladophylls of glasshouse-grown Texas pricklypear cactus (Opuntia engelmannii var. texana [Gr.] Weniger). Alkane content increased with cladophyll age. Ester content decreased from 56% on buds to 17% on older cladophylls.

Composition of Epicuticular Wax on Prosopis glandulosa Leaves

Botanical Gazette, 1990
Epicuticular wax on leaves of field-grown honey mesquite (Prosopis glandulosa Torr.) trees consisted of 35% esters, 32% alkanes, 25% free fatty alcohols, and 7% free fatty acids. Aldehydes were present in very low concentrations. The number of carbon atoms (Cn) of alkanes ranged from 25 to 31, with a maximum (57%) at 29. Esters consisted of fatty acids

Composition of leaf epicuticular waxes of Pteridium subspecies

Phytochemistry, 1987
Abstract The leaf epicuticular waxes of two subspecies of Pteridium consisted principally of alkyl esters (92 %; C 40 –C 50 ) together with small amounts of n -alkanols (2 %; C 24 –C 32 ) and hydrocarbons (2%; C 27 –C 31 ). The esters comprised C 22 –C 32 alkanols randomly combined with C 20 – C 24 fatty acids.

Composition and structure of maize epicuticular wax esters

Phytochemistry, 1989
Abstract The structural composition is reported of epicuticular wax esters from maize. The waxes from wild type ( Gl ) plants at different stages of growth and those from some glossy ( gl ) seedlings and an albino strain of maize have been analysed for their content of esters. Influence of age and mutations on the epicuticular wax ester composition

Chemical Composition and Recrystallization of Epicuticular Waxes: Coiled Rodlets and Tubules

Plant Biology, 2000
Abstract: Coiled rodlets characterize several non‐related taxa within the angiosperms. They often occur together with tubules but sometimes also with platelets or transitional forms between them. The ultrastructure chemistry, and recrystallization of epicuticular waxes of three species were investigated by high‐resolution scanning electron microscopy,

Effects of Air Pollutants on Epicuticular Wax Chemical Composition

1994
There are numerous reports in the literature of modifications to epicuticular wax structure as a consequence of exposure to air pollutants. Most authors have used scanning electron microscopy (SEM) to describe changes in wax crystallite morphology or distribution.

Relationship of epicuticular wax composition of grapefruit to chilling injury

Journal of Agricultural and Food Chemistry, 1991
Cold storage affects amounts of alkanes, squalene, and long-chain aldehydes in the epicuticular wax of grapefruit. Levels of these components were determined in fresh grapefruit prior to cold storage and in temperature-conditioned and nonconditioned fruit after storage at various times and temperatures.
