Effect of Salinity on Phenolic Composition and Antioxidant Activity of Artichoke (Cynara scolymus L.) Leaves. Research Journal of Medicinal Plant, 6(3). Artichoke The globe artichoke ("Cynara cardunculus" var. "scolymus") is a variety of a species of thistle cultivated as a food. The edible portion of the plant consists of the flower buds before the flowers come into bloom. The budding artichoke flower-head is a cluster of many budding small flowers (an inflorescence), together with many bracts, on an edible base. Once the buds bloom,
Rational variety Rational variety In mathematics, a rational variety is an algebraic variety, over a given field "K", which is birationally equivalent to a projective space of some dimension over "K". This means that its function field is isomorphic to the field of all rational functions for some set formula_2 of indeterminates, where "d" is the dimension of the variety. Let "V" be an affine algebraic variety of dimension "d" defined by a prime ideal "I"=⟨"f", ..., "f"⟩ in formula_3. If "V" is rational, then there are "n"+1 polynomials "g", ..., "g" in formula_4 such that formula_5 In order words, we have
