Wytrzymałość mechaniczna korzeni buraków cukrowych

Wyznaczono granicę wytrzymałości biologicznej tkanki korzenia buraka na podstawie wartości naprężeń niszczących i energii pęknięcia. Obserwowano mikroskopem skaningowym rodzaj uszkodzeń tkanki.

The resistance to compression is the feature of tissue which allows the evaluation of the root concerning its resistance to mechanical damage. The limit of biological resistance is determined by breaking stress and energy of fracture assigned by a static compression test. During the investigations these parameters were determined according to the measurement zones. The object of research was the roots PN Mono 1 variety. The lowest resistance to compression has been found in the lower part of the root, where the oldest strips of sieve and wood tissue bundles are predominant. The observation of damaged tissue of sugar beet roots was performed by using scanning microscope. The experiment allowed to determine the character of damage to the root tissue.
