Mannheim, Germany (PRWEB) May 04, 2012
The spears of the temperate cultivars of "white" Asparagus (Asparagus officinalis, Asparagaceae or Liliaceae) are harvested belowground whereas those of the sub-/tropical "green asparagus" are cut aboveground. During belowground etiolation white Asparagus is deprived of light during its whole cultivation period. This "white Asparagus" is the preferred type of Asparagus in Europe. Since green asparagus is allowed to extend its stems beyond the soil surface, these stems develop chlorophyll and, thus, become green.
While asparagus is a low-calorie source of folate and potassium, its stalks are high in antioxidants, potassium and folate. Folate is known to reduce synthesis of homocysteine, a substance promoting heart disease. Foliate also protects against neural tube defects in babies, and against Alzheimer's Disease.
The general Asparagus section provides information about the aspects of production of vegetables including cultivation, pests and diseases, harvest, postharvest, storage and marketing. The "Asparagus Production Management and Marketing Bulletin" published by Ohio State University Extension is the most popular resource in the general section for Asparagus.
The Asparagus research section contain scientific information and links to peer-reviewed papers, journal articles, theses, books, abstracts, and other scholarly literature on the individual vegetables. The page on "Poisonous Plants: Asparagus officinalis" published by the North Carolina Cooperative Extension Service of the North Carolina State University is currently the most popular page in the Research category of Asparagus.
