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 of epicuticular wax of rice,Oryza sativa

Experientia, 1979
The epicuticular wax of rice, varietyRibe, comprised n-alkanes, esters, aldehydes and free alcohols. The nalkanes contained 4 major chain lengths, C27, C29, C31 and C33. Triacontanal and dotriacontanal were the major aldehydes. Octacosanol comprised 89% of the free alcohols. The esters were mainly esters of C16 to C24 acids with C22 to C30 alcohols.

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,

Ultrastructure, chemical composition, and recrystallization of epicuticular waxes: transversely ridged rodlets

Canadian Journal of Botany, 1999
Transversely ridged rodlets (Aristolochia-type) are of high systematic significance characterizing the ancestral Aristolochiales, Magnoliales, and Laurales. Sporadically, they also occur in various unrelated derived taxa. The ultrastructure, chemistry, and recrystallization of epicuticular waxes of nine species were investigated by high resolution ...

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.

Correlations between Epicuticular Wax Structures and Chemical Composition in Arabidopsis thaliana

International Journal of Plant Sciences, 1998
The epicuticular waxes of vascular plants are both chemically and structurally diverse. This investigation attempts to clarify the poorly understood relationships between epicuticular wax chemicals and structures by correlating the diversity of chemical compositions and structures in wildtype and epicuticular wax mutants of Arabidopsis thaliana.

Chemical composition of the epicuticular wax from the fruits of Eucalyptus globulus

Phytochemical Analysis, 2005
AbstractThe chemical composition of the epicuticular wax from the fruits of Eucalyptus globulus was studied by GC‐MS before and after alkaline hydrolysis. The wax had two main components, ursolic acid and tritriacontan‐16,18‐dione, together with several other triterpenic acids.

Epicuticular waxes of Sorghum and some compositional changes with plant age

Phytochemistry, 1984
Abstract Epicuticular wax from mature plants of Sorghum bicolor SD-102 was compared with that from panicles and seedlings of the same variety at the fourth-fifth leaf stage of growth. The composition of wax from SD-102 panicles was quite different from that of mature leaf blades and sheaths.

Intraspecific Variation in the Epicuticular Wax Composition of Four Species of Chionochloa

Biochemical Systematics and Ecology, 1983
Intraspecific variation in four New Zealand species of Chionochloa, C. flavescens, C. pallens, C. rigida; and C. rubra, was investigated by examining the major carbon chain lengths of fatty acids, alcohols, aldehydes, wax esters and alkanes of the epicuticular waxes.
