The olive tree (Olea europaea L.) has a cultural, economic, and environmental importance in the Mediterranean region. The aim of this four-year study was to investigate the shoot growth dynamics of four olive cultivars ('Arbequina', 'Coratina', 'Frantoio', and 'Urano') grown in a super high-density (SHD) orchard under Mediterranean climate. Using a logistic regression, we analyzed the elongation of apical proleptic, lateral proleptic, sylleptic, and adventitious shoots. Nevertheless no significant difference was showed between type of shoot and cultivar, results indicate that single-phase logistic growth was the most pattern, except to the lateral proleptic shoots of 'Coratina' and adventitious of 'Urano', where a second vegetative flush occurred. No correlation of Growing Degree Days with the shoot growth was observed. As confirmed in previous studies, crop load showed a negative influence on shoots elongation.Particularly for Arbequina's adventitious shoots, Coratina's and Frantio's sylleptic shoots and Urano's lateral proleptic this trend was observed. This evidence showed the potential competition between reproductive and vegetative cycle for assimilates. To our knowledge, this is the first report addressing the vegetative growth dynamics of four different shoot types of four distinct olive cultivars with different vigor in an SHD system. These findings are essential for optimizing cultivar-specific agricultural strategies (e.g. canopy management and irrigation), to achieving an optimal yield and sustainable cultivation.
