The beet in the clamp is living and living demands energy

Respiration

Causes for genotypic differences in storage losses of sugar beet

Low susceptibility to damage Less entry points for pathogens Genotypes with high tissue stability Low storage losses! Less wound heeling processes Low enzyme activity and respiration rate Carbohydrate metabolism Susceptibility to damage Pathogen infestation Less penetration and spread of pathogen Unspecific resistance

(Schnepel & Hoffmann 2014)
