ORIGIN, DIFFUSION, IMPORTANCE

The origin is rather uncertain, it has diffused in the Florence and Pistoia area, and cultivated all over the world.
The tolerance of this cultivar, to climatic stress (cold, fog and wind) is well-known and to some diseases :olive knot (Pseudomonassusps.savastanoi),olive leaf spot (Spilocaea oleagina)and rot (1, 2, 3).
It is susceptible to sooty moulds (3).

AGRONOMIC CHARACTERS

Self-sterile. Small percentage (10%) of aborted flowers (1, 2, 3).
Excellent pollinators are: "Gremignolo di Bolgheri", "Maremmano", "Pendolino" and "Morchiaio" olives; fairly good are also: "Piangente", "Frantoio" and "Trillo" olives(2, 3).
Flowering occur end of May, early June and its fruits are placed mainly in the central and lower region of the branches (3).
The production is high and constant (1, 3) and ripening is early and uniform (1).
The fruits are used for oil extraction and black table olive production (3).
