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
Affine variety Affine variety In algebraic geometry, an affine variety over an algebraically closed field "k" is the zero-locus in the affine "n"-space formula_1 of some finite family of polynomials of "n" variables with coefficients in "k" that generate a prime ideal. If the condition of generating a prime ideal is removed, such a set is called an (affine) algebraic set. A Zariski open subvariety of an affine variety is called a quasi-affine variety. If "X" is an affine variety defined by a prime ideal "I", then the quotient ring is called the coordinate ring of "X". This ring is precisely the
