Agronomic behavior of cardoon cultivars in Navarre
Cardoon (Cynara cardunculus L. var. altilis DC) is a species of Mediterranean origin whose cultivated area, a few thousand hectares, is located mainly in Spain, Italy, France and Greece. In Spain, the main cardoon production area is Navarra, with almost 300 ha and a production destined for the most part to the canning or freezing industry (approximately 80%) and the rest to the fresh market. The cultivation of cardoon in Spain is based on traditional cultivars, adapted to the local agroclimatic conditions, which have been originated by selection processes carried out by the farmers themselves. The general objective of this work was to evaluate different plant material of cardoon in the traditional culture and industrial transformation conditions of Navarre, based on the canning of the blanched leaf stalks. For this purpose, an agronomic evaluation (yield) and characterization based on its industrial aptitude has been carried out in 14 cultivars of cardoon from Spanish, French and Italian origin. Also, samples of these cultivars were analyzed to determine the total antioxidant capacity (TAC) and the content of free and total polyphenols, cynarine and dietary fiber. The obtained results show a great variability among cultivars. The highest yield was obtained with Verde de Calahorra and Verde de Peralta. For their industrial aptitude the ones that stand out were Blanco de Peralta and Verde de Peralta.
