Voorbeelden van lignin

• During lignification, phenyl rings of lignin precursors align to the cellulose molecule surfaces in a controlled and ordered process.

• Parasites were identified using the standard keys and, where necessary, they were cleared in lactophenol or stained with polyvinyl acetate and lignin pink.

• There is generally a higher expression of genes involved in cellulose and lignin biosynthesis in the wild-type testa as compared to the mutant.

• This is largely determined by the age of the late wood that is likely to have high lignin content.

• Modified procedure to determine acid insoluble lignin in wood and pulp.

• This may relate to covalent binding of lignin to hemicellulose, which confers mechanical strength to the cell wall.

• This implies that the construction of leaf biomass is different among lifeform categories (for example lignin versus cellulose versus others).

• The combination of phloroglucinol and hydrochloric acid stains the lignin red and increases visibility of annual rings, particularly in the softer wood of young trees.

• Carbohydrates and lignin of plant materials used in animal production.

• By feeding on plant parts with high lignin content or fibrous tissues, a ruminant fails to assimilate enough protein for its maintenance requirement.

• High spectral resolution remote sensing of forest canopy lignin, nitrogen and ecosystem process.

• The mature mutant testa has reduced amounts of cellulose and lignin as compared to the wild type.

• We measured dry weight, pericarp thickness and concentrations of nitrogen, total phenol, condensed tannin, lignin, lipid, starch and total sugar.

• The lignin content, polyphenols and the overall chemical composition of the crop residue also affects their use as organic manures.

• Nitrogen immobilisation in decaying hardwood leaf litter as a function of initial nitrogen and lignin content.
