Artichoke production in Italy artichoke to Florence. By 1473, it had arrived in Venice. In 1915, 64,000 tons were produced. Italy produces dozens of varieties. Artichoke production in Italy Artichoke production in Italy has a long history. Italy is the world's largest producer of artichokes. With Spain and France, the three countries produce more than 80% of the world's artichokes. There are two theories as to its origin: artichokes may have come from the Levant, derived from the cardoon or thistle through a cross-fertilization process, while others attribute it to the work of Italian horticulturists. The first record of artichoke cultivation in Italy was
Variety of finite semigroups "the set of semigroup as a variety of universal algebra over the vocabulary of one binary operator". It follows from the definitions of those two kind of varieties that, for any variety "V" of (arbitrary) semigroups, the set of finite semigroups of "V" is a variety of finite semigroups. We first give an examples of variety of finite semigroup which is not similar to any subvariety of the variety of (arbitrary) semigroups. We then give the difference between the two definition using identities. Finally, we give the difference between the algebraic definitions. As shown above, the set of finite group
