Abstract
Recently artichoke seed propagated cultivars, have been widespread introduced in the commercial fields and often they represent a valid alternative to the traditional vegetatively propagated material.
In this paper the yield traits evaluation and the harvesting time of seven artichoke seed grown hybrids are reported.
Open field trials were carried out in Policoro, southern Italy; seeds of Amos, Rinaldo, Ernesto, Romano and Napoleone (supplied by Agriseeds), Istar (furnished by La Semiorto Sementi), Madrigal, (provided by Nunhems), were sown in the first week of June in polystyrene trays.
The seedlings were grown in a cold greenhouse until the stage of 3rd-4th true leaf and then transplanted in the field.
In comparison, Violetto di Provenza was planted in the same date using rooted offshoots.
Three GA3 treatments at 5 ppm were applied to the foliage of all plants at three week intervals, using aqueous solution acidified to pH 4 with urea phosphate.
Heads were harvested from October to May; the main yield parameters and the heads morphological traits were recorded at each harvest.
The refuse of small buds trimmed before processing, the height of the inflorescence complex and atrophic buds were also determined.
The highest number of heads per hectare was harvested by Madrigal with about 194.000 heads ha-1; good production was recorded by Istar, Rinaldo, Ernesto and Amos, with an average of 145,000 heads ha-1 as well as Violetto di Provenza. Romano, Madrigal and Napoleone produced the higher weight main heads, about 250 g on average.
Height of pappus, dry matter and fiber content progressively increased in heads harvested from March to May.
Harvest season was comprised from October to May.
Good earliness was recorded by Istar and Violetto di Provenza (first harvest in October), whereas Napoleone resulted the latest (beginning of harvest in February).
