Sažetak
During an olive fruit growing and development it begins a pit (endocarp) lignification and after ending this phenophase begins an olive oil accumulation in olive fruit pulp (mesocarp). Knowledge of this phase duration and ending is important because of time definition and modality of agrotechnical procedures, irrigation and pest management as well as in table olive production for olive fruit thinning in order to obtain uniform fruit weight and size. In the present research length, width and weight of Istrian autochthonous olive varieties Buža, Buža puntoža, Rosinjola and Istarska bjelica were measured. Study was done in olive collection orchard of the Institute of Agriculture and Tourism in Poreč in equal growing conditions. The aim of research was to define an olive fruit growth dynamics during pit hardening whereby in further research we could determine correlation between growth and weather conditions during this phenophase. Fruit weight in all varieties was increasing during endocarp lignification (from 7th to 28th July). The highest percentage in the first week had varieties Buža (48, 5%) and Rosinjola (44, 6%) and in the second week maximum was reached by varieties Buža puntoža (44, 2%) and Istarska bjelica (42%). Peak in total fruit mass increase was detected at Buža puntoža (1, 30 g), and least at Rosinjola (0, 56 g). Maximum increase in length (L) and width (W) had Buža puntoža (L: 7, 13mm ; W: 4, 23mm) and least Istarska bjelica (L: 2, 48mm ; W: 2, 70mm).
