In the North-West of Sardinia (Italy) a two-year experiment was carried out during 1999-2000 and 2000-2001 to test plant shading and ovoli typology effect on the development, early production and head atrophy of globe artichoke (Cynara cardunculus L. var. scolymus Fiori) cv "Spinoso sardo". Four intensities of plant shading (0%, 30%, 60% and 90%) were combined as main plots with two ovoli typologies (ovoidi and sigaroidi) as subplot in a split-plot experiment design with four replications. From 6 to 28 July 1999 and from 11 July to 7 August 2000 the four shading intensities were applied in the nursery after the ovoli dormancy breaking, before transplanting the plant from pots to the open field at the 3rd leaf stage. All the early produced heads were harvested and measurements were taken on stem weight, head diameter, length and weight. The intensity of shading influenced head weight, head atrophy, the percentage of early productive plants, the number of early harvested heads and the number of leaves per plant. The ovoli typology influenced the number of early harvested heads, the stem weight, the head weight, the head atrophy and the number of leaves per plant.

Abstract

In the North-West of Sardinia (Italy) a two-year experiment was carried out during 1999-2000 and 2000-2001 to test plant shading and ovoli typology effect on the development, early production and head atrophy of globe artichoke (Cynara cardunculus L. var. scolymus Fiori) cv "Spinoso sardo". Four intensities of plant shading (0%, 30%, 60% and 90%) were combined as main plots with two ovoli typologies (ovoidi and sigaroidi) as subplot in a split-plot experiment design with four replications. From 6 to 28 July 1999 and from 11 July to 7 August 2000 the four shading intensities were applied in the nursery after the ovoli dormancy breaking, before transplanting the plant from pots to the open field at the 3rd leaf stage. All the early produced heads were harvested and measurements were taken on stem weight, head diameter, length and weight. The intensity of shading influenced head weight, head atrophy, the percentage of early productive plants, the number of early harvested heads and the number of leaves per plant. The ovoli typology influenced the number of early harvested heads, the stem weight, the head weight, the head atrophy and the number of leaves per plant.
