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.

Chemotaxonomic significance of leaf wax alkanes in the gramineae

Biochemical Systematics and Ecology, 1996
Abstract Leaf wax alkanes were determined in several species of the grass family (Gramineae) and used as chemotaxonomic characters. Leaf wax alkanes were extracted with hexane and determined by GC-MS on a data set including 93 species belonging to five subfamilies: Bambusoideae, Pooideae, Arundinoideae, Chloridoideae and Panicoideae.

An apparent seleniferous leaf wax from Stanleya bipinnata

Biochemical and Biophysical Research Communications, 1963
Selenium75 was used as a tracer to demonstrate that Se is intimately associated with leaf wax from Stanleya bipinnata, a member of the mustard family. Results are reported from studies that suggest, but do not conclusively prove, that Se is a chemical part of the wax molecules.

Leaf wax of Lactuca sativa and Plantago major

Phytochemistry, 1998
Abstract Wax layers of plants are able to accumulate semivolatile organic compounds (SOCs) from the atmosphere. In this study, the composition of the leaf cuticular waxes of lettuce ( Lactuca sativa ) and common plantain ( Plantago major ) was determined for future studies on the role of cuticular waxes in the uptake and bioaccumulation of SOCs.

Effects of leaf surface wax on leaf spectrum and hyperspectral vegetation indices

2013 IEEE International Geoscience and Remote Sensing Symposium - IGARSS, 2013
Many hyperspectral vegetation indices can be used to estimate the biochemical contents such as pigment content, nondestructively. These reflectance indices are influenced by some leaf surface structure, such as wax, and the existence of the wax affects the performance of the indices on the estimation of the biochemical contents.

Chemistry of leaf waxes in relation to wetting

Journal of the Science of Food and Agriculture, 1969
AbstractThe hydrophobic property of waxes depends upon their chemical constitution and almost certainly upon the orientation of molecules of their constituents. Contact angles of the most important classes of constituent range from 94° to 109°. No class of constituent is very water‐repellent; alkenes are the most hydrophobic but esters, ketones and ...
