ABSTRACT
Mechanical properties of an apple tissue were examined and stress relaxation model was proposed. Rheological model of an apple tissue consists of 5 elements. This model described relaxation of the compressed material well taking into account tissue structure and its alteration by the force. A proposal to treat plant tissue as an aggregate of cells dependent on one another in which single cells are surrounded by a visco-elastic cell wall was put forward.

W pracy badano właściwości mechaniczne tkanki jabłka i zaproponowano model relaksacji naprężeń miąższu. Zbudowany pięcioelementowy model tkanki jabłka dobrze opisywał relaksację uwzględniając zachowanie elementów struktury tkanki. Założono, że tkanka roślinna to zespół zależnych od siebie komórek, w którym pojedyncze komórki roślinne otoczone są lepkosprężystą ścianą komórkową.
