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,
Secant variety Secant variety In algebraic geometry, the secant variety formula_1, or the variety of chords, of a projective variety formula_2 is the Zariski closure of the union of all secant lines (chords) to "V" in formula_3: (for formula_5, the line formula_6 is the tangent line.) It is also the image under the projection formula_7 of the closure "Z" of the incidence variety Note that "Z" has dimension formula_9 and so formula_1 has dimension at most formula_9. More generally, the formula_12 secant variety is the Zariski closure of the union of the linear spaces spanned by collections of k+1 points on formula_13.
