Abstract

[Autom. eng. transl.] The research was conducted in Central Italy in 2009-2014, with the aim of evaluating the effects of different annual, biennial and three-year pruning shifts on vegetative-productive activity and on physiological aspects of plants and on the quality of oil. For annual pruning, criteria of simplification have been applied: cuts on wood over 2-3 years of age, elimination of vigorous suckers only, elimination of exhausted small branches every other year, not seeking a strong geometric regularity and greater flexibility in the management of supernumerary branches, execution from the ground without stairs. The olive grove is made up of cv Frantoio plants, planted in pots, arranged at 6 × 5. The pruning shift has significantly influenced the density of the claw, which can be estimated with the LAI measurement, and of the volume of vegetation. The pruning shifts determined strong differences in the production per plant trend, with a variability between the years increasing with the increase of the pruning round, while no substantial differences were found on the cumulative production obtained during the period. derato. The shift influenced the growth of fruits and the process of forwarding. The prevalence of productive activity over vegetative activity was more constant and greater in the fruit-bearing branches of plants pruned annually. The growth of the shoots has been considerably influenced by the shift. The plants pruned with biennial and triennial shift produced a greater quantity of suckers especially in the year in which the pruning was performed. The photosynthetic activity and the relative water content of the leaves and fruits were influenced by the shift. The times for pruning expressed as an average per year were relatively low (<10 minutes per year) and were not substantially different between the different shifts applied, indicating that the application of simplification criteria for annual pruning it allows to reduce the differences with the biennial and three-year shifts. The pruning shift did not substantially affect the merit quality of the oils. In conclusion, the results indicate that the pruning shift determines in the years differences in the vegetative and productive cycles, with repercussions on the regularity of the productions, on the distribution of the assimilated between vegetative and productive activity, on water relations and photosynthetic activity of the leaves and product quality.
