INFLUENCE OF OVOLI SIZE ON PRODUCTION AND EARLINESS IN DIFFERENT ARTICHOKE CULTIVARS

Vegetative propagation by ovoli in artichoke is an interesting technique that is not fully introduced in Spain.
Agronomic behaviour was studied in three artichoke cultivars ‘Thema’, ‘Romanesco’ and ‘Spinoso Sardo’ propagated by ovoli.
Influence of ovoli size on production and earliness was estimated in this primary study.
Per each cultivar, ovoli were divided in two groups and designed as big size ovoli (50-80 mm) or small size ovoli (<50 mm). The production of plants derived from big size ovoli was not significant compared with small size ovoli production.
Only ‘Romanesco’ showed statistical differences with the big size ovoli more productive (2.66 kg/plant) than small size ones (1.17 kg/plant). Earliness was not influenced by ovoli size in ‘Romanesco’ and ‘Spinoso Sardo’. On the contrary, differences were found in ‘Thema’ where early production was higher (65%) in plants derived from big size ovoli than in small size ovoli (25%).
