Learn about the various parts of a flower, floral types, and pollination with this article.

[88], The most common forms of wheat are white and red wheat. This article is about the plant. Archaeological analysis of wild emmer indicates that it was first cultivated in the southern Levant, with finds dating back as far as 9600 BCE. In sprouted or cooked form, the relative nutritional and anti-nutritional contents of each of these grains is remarkably different from that of raw form of these grains reported in this table. Wheat buyers use these to decide which wheat to buy, as each class has special uses, and producers use them to decide which classes of wheat will be most profitable to cultivate. The popularity of foods made from wheat flour creates a large demand for the grain, even in economies with significant food surpluses. In culinary terminology, a fruit is usually any sweet-tasting plant part, especially a botanical fruit; a nut is any hard, oily, and shelled plant product; and a vegetable is any savory or less sweet plant product. Wheat has also been the subject of mutation breeding, with the use of gamma, x-rays, ultraviolet light, and sometimes harsh chemicals. In the 19th century, efforts were made to hybridize the two do get a crop with the best traits of both. Great expansion of wheat production occurred as new arable land was farmed in the Americas and Australia in the 19th and 20th centuries. There were significant profitability differences between low- and high-cost farms, due to crop yield differences, location, and farm size. Wheat is widely cultivated as a cash crop because it produces a good yield per unit area, grows well in a temperate climate even with a moderately short growing season, and yields a versatile, high-quality flour that is widely used in baking. Thus technological innovation and scientific crop management with synthetic nitrogen fertilizer, irrigation and wheat breeding were the main drivers of wheat output growth in the second half of the century. • The unit is called spikelet. Z raw plantains 'Lodging' occurs when an ear stalk falls over in the wind and rots on the ground, and heavy nitrogenous fertilization of wheat makes the grass grow taller and become more susceptible to this problem. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed. [10] Significant efforts in plant breeding are being made to develop lysine-rich wheat varieties, without success as of 2017. It is still used for bulgur (cracked wheat) or as animal feed, in mountainous areas of France, Libya, former Yugoslavia, Turkey and other countries. Wheat is 13% water, 71% carbohydrates, and 1.5% fat. Wheat is the staple food for 35 percent of the world's population and provides more calories and protein in the diet than any other crop [3] . Floral formula and floral diagram of wheat. In the wild, the awns of emmer wheat spikelets help them dig into the soil. Dated archeological remains of einkorn wheat in settlement sites near this region, including those at Abu Hureyra in Syria, suggest the domestication of einkorn near the Karacadag Mountain Range. Other commercially minor but nutritionally promising species of naturally evolved wheat species include black, yellow and blue wheat. A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Magnoliophyta, also called angiosperms).The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs.
