Zmiany w sk?adzie chemicznym ?d?b?a zbóz w fazie k?oszenia przy ró?nym poziomie nawo?enia mineralnego [Changes in the chemical composition of corn culms and their ear-forming stage depending on mineral fertilization]

摘要

A study was curried out on the influence of mineral fertilization on the chemical composition of the cell walls of culms of wheat, barley, rye, and oats at the ear-forming stage. The content of reducing sugars, protein, pectin substances, hemicellulose, lignin, ash, and α-cellulose has been determined as well as the distribution of some of the micro- and macroelements in the lower and the upper parts of culm.
