| Abstract:
In an experimental field located in the plain of Catania - Sicily (37°27' N, 15°4' E, 10 m a.s.l.), grain yield and chemical characteristics of ten wild cardoons (Cynara cardunculus L. var. sylvestris Lam.) and one globe artichoke (C. scolymus L.) cv. ‘Violetto di Sicilia’, were evaluated. The grain yield resulted, on average, 0.69 t ha-1 in wild cardoon and it exceeded 1 t ha-1 with two genotypes ‘MSA1’ and ‘B2’; a 0.35 t ha-1 grain yield was obtained in globe artichoke. The grain of wild cardoon showed a content ranging from 199 to 249 g Kg-1 of crude oil, from 185 to 225 g Kg-1 of crude protein, from 183 to 219 g Kg-1 of crude fibre, from 110 to 133 g Kg-1 of total sugar, from 35 to 40 g Kg-1 of ash and from 194 to 235 g Kg-1 of Nitrogen Free Extract (dry weight basis). The results of this study showed the potential of wild cardoon to produce grain with good chemical-nutritive characteristics even with a low input management. In this research, the obtained productions are to be considered very promising, especially because the crop is in the first year and no genotype has been grown for grain in the past. Moreover the variability observed especially for crude oil content, may provide the basis for further improvements. | |
