Kvinoja (Chenopodium quinoa; /ˈknwɑː/ or /kɪˈn.ə/, from Quechua kinwa or kinuwa)[2] is a flowering plant in the amaranth family. It is a herbaceous annual plant grown as a crop primarily for its edible seeds; the seeds are rich in protein, dietary fiber, B vitamins, and dietary minerals in amounts greater than in many grains.[3] Quinoa is not a grass, but rather a pseudocereal botanically related to spinach and amaranth (Amaranthus spp.), and originated in the Andean region of northwestern South America.[4] It was first used to feed livestock 5.2–7.0 thousand years ago, and for human consumption 3–4 thousand years ago in the Lake Titicaca basin of Peru and Bolivia.[5]

Today, almost all production in the Andean region is done by small farms and associations. Its cultivation has spread to more than 70 countries, including Kenya, India, the United States, and several European countries.[6] As a result of increased popularity and consumption in North America, Europe, and Australasia, quinoa crop prices tripled between 2006 and 2013.[7][8]

Opis

Chenopodium quinoa je dicotyledonous annual plant, usually about 1–2 m (3–7 ft) high. It has broad, generally powdery, hairy, lobed leaves, normally arranged alternately. The woody central stem is branched or unbranched depending on the variety and may be green, red or purple. The flowering panicles arise from the top of the plant or from leaf axils along the stem. Each panicle has a central axis from which a secondary axis emerges either with flowers (amaranthiform) or bearing a tertiary axis carrying the flowers (glomeruliform).[9] These are small, incomplete, sessile flowers of the same colour as the sepals, and both pistillate and perfect forms occur. Pistillate flowers are generally located at the proximal end of the glomeruli and the perfect ones at the distal end of it. A perfect flower has five sepals, five anthers and a superior ovary, from which two to three stigmatic branches emerge.[10]

The green hypogynous flowers have a simple perianth and are generally self-fertilizing[9][11] though but cross-pollination occurs.[12] Furthermore, in the natural environment, betalains serve to attract animals to generate a greater rate of pollination and ensure, or improve, seed dissemination.[13] The fruits (seeds) are about 2 mm (116 in) in diameter and of various colors — from white to red or black, depending on the cultivar.[14]

In regards to the “newly” developed salinity resistance of C. quinoa, some studies have concluded that accumulation of organic osmolytes plays a dual role for the species. They provide osmotic adjustment, in addition to protection against oxidative stress of the photosynthetic structures in developing leaves. Studies also suggested that reduction in stomatal density in reaction to salinity levels represents an essential instrument of defence to optimize water use efficiency under the given conditions to which it may be exposed.[15]
