ABSTRACT
Comparative study of root mechanical properties of four sugar beet cultivars over harvest and storage periods in the conditions of static loads were carried out including determination of some mechanical parameters of beet root skin in two measurement zones within the applicability range of the Hook’s law. Tests concerning the effect of cultivar and measurement zone on tested parameters were performed on a micro tensile tester, Zwick model 1425 in the Department of Agricultural Production Technology. The average values of skin destruction forces were 241.22 254.1 N and 227.4 245.8 N for freshly harvested sugar beet roots and after 45 days of storage, respectively.
