PRODUCTIVE BEHAVIOUR OF DIFFERENT CULTIVARS AND LINES OF SEED PROPAGATED ARTICHOKE IN THE SPANISH MEDITERRANEAN AREA
The most interesting artichoke production period in the Spanish Mediterranean Coast is autumn-winter. Seeds of seven cultivars (Imperial Star, Alberca, Harmony, Concerto, Madrigal, Opal and Lorca) and five lines (DS-1000, DS-2000, AR-1, AR-2 and AR-3) were sown in polystyrene trays on 14 June 2005 and planted on 1 August in south Valencia, Spain. Blanca de Tudela and Violeta de Provenza, which are asexually propagated cultivars, were planted in the same date and used as controls. Three replicates of 10 plants per cultivar/line were arranged in a completely randomized design. All cultivars and lines were sprayed three times between 20 September and 20 October 2005 with gibberellic acid at 30 mg L-1. Harvest started in October for Blanca de Tudela and among seed propagated cultivars/lines, Imperial Star and Lorca (beginning harvest in November) were the earliest, while Concerto and Madrigal (beginning harvest in February) were the latest. At the end of February 2006, Imperial Star (0.72 kg m-2 of market yield), Blanca de Tudela, Lorca and DS-1000 (0.66 kg m-2 for all three), were the most productive varieties. The highest total market yields (until the end of May 2006) were obtained in Madrigal (2.28 kg m-2), Concerto (1.86 kg m-2), AR-3 (1.77 kg m-2) and DS-1000 (1.69 kg m-2). Whereas the highest non-marketable yields were reached by AR-2 (1.05 kg m-2), AR-3 (0.84 kg m-2) and DS-2000 (0.78 kg m-2). Furthermore at the end of the experiment (end of May), there were not differences among cultivars/lines, for the variable head size (between 91 and 157 g), however some statistically differences during some controls made over the productive cycle were detected for this parameter.
