Knowra Turnip Turnip Turnip is a cultivated form of Brassica rapa grown for its edible swollen root and leafy greens. Its roots and leaves are eaten as vegetables and used as livestock feed.
Brassica rapa : A variable mustard species that includes turnips, napa cabbage, bok choy, and several other cultivated vegetables. Turnips are one cultivated form within this species.
Turnip greens : The edible leaves of turnip plants, commonly cooked as a leafy vegetable. They are harvested separately from the swollen root and have their own culinary uses.
Domestication of plants : The process by which human selection transforms wild plants into crops adapted to cultivation and use. Turnip's enlarged root reflects generations of selection within Brassica rapa.
Plant storage organ : A plant structure that accumulates energy reserves, often enabling survival through unfavorable seasons. A turnip root stores carbohydrates that support later growth.
Brassicaceae : The mustard family of flowering plants, including cabbages, mustards, radishes, and their relatives. Turnip belongs to this family, whose members often share pungent compounds.
Root cellar : A cool, humid storage space traditionally used to preserve root crops and other produce. Cool storage helps keep harvested turnips firm for winter use.
Brassica rapa subsp. rapa : A cultivated subspecies of Brassica rapa that includes turnips and several related root crops. This taxonomic grouping includes turnips and distinguishes them from leafy forms.
Photoperiodism : A biological response to the relative lengths of day and night, influencing processes such as flowering. Day length affects when turnips shift from vegetative growth toward flowering.
Root vegetable : A crop grown chiefly for an edible underground root or other subterranean storage organ. The turnip's enlarged storage root is its best-known edible part.
Pickling : Food preservation by immersing ingredients in acidic brine or fermenting them in salt. Turnips are preserved this way in dishes such as Middle Eastern pickled turnips.
