Abstract In this study, the effects of aminoethoxyvinylglycine ( AVG ) treatments on the mechanical behaviour of plum fruits (cv. P resident) were determined. The mechanical behaviour of plum fruits was determined in terms of rupture force, deformation at rupture point, absorbed energy and hardness. AVG treatments were as 0, 100, and 200 mg/L, and three different harvest times including A ugust 28, S eptember 4, and S eptember 11 were used. The highest rupture forces required when loading along the y ‐axis were found as the AVG doses increased through the three harvesting times categories; whereas, the lower force was required to rupture plum fruits with high 200 mg/L AVG values being tested for x ‐loading orientation. The deformation at rupture point values observed for plum fruits compressed along the y ‐axis were higher than those of the other orientations except for AVG dose of 100 mg/L for second harvesting time. Whereas, the absorbed energy and hardness of plum fruits tested along the y ‐axis in 0 mg/L and along the z ‐axis in 200 mg/L AVG treatments were higher than those of the other orientations, respectively. Practical Applications Plum has an important place in total fruit production of T urkey. Plum has a fast decay of within 1–8 weeks. Aminoethoxyvinylglycine ( AVG ) is an inhibitor of ethylene and it is a human and eco‐friendly organic product, it was used in apples, pears, peaches, plums and nectarines. AVG delays ripening and harvest of fruits, increases fruit firmness and prolongs shelf life. Plant growth regulators improve and protect of fruit quality. Growth regulatory substances have been evaluated among factors causing changes of the physical, mechanical and chemical properties of fruits. The mechanical properties of agricultural materials are to be known for design and improvement of relevant machines and facilities for harvesting, storing, handling and processing. Processing of plum fruits as juice and marmalade consist of a mechanical treatment of the plum (rupture force, deformation at rupture point, absorbed energy and hardness etc.), they are must eventually be analyzed with knowledge of the mechanical behavior of the plum.
