![]() ![]() The elasticity and extensibility of dough are the basic characteristics of breadmaking and are largely determined by the glutenin and gliadin content of the flour, respectively. They are the main components of gluten in wheat flour. Wheat endosperm proteins, the prolamins, can be divided into gliadins and glutenins according to their polymerization properties. Īs well as being a major source of carbohydrate in the form of starch, wheat seeds also provide a great source of protein in the human diet. These morphological effects of domestication facilitated the cropping of wheat, leading to an exponential increase in its economic importance. The progressive domestication of these wheat species led to the restructuring of the rachis and glumes, converting the brittle ears of wild species into non-brittle and bare grain ears in cultivated species. The most important varieties of modern wheat are tetraploid durum wheat ( Triticum durum) and hexaploid bread wheat ( Triticum aestivum L.), which have different attributes in terms of genomic composition, grain composition, and end use. Spring wheat is planted in spring and harvested in late summer or fall in South Asian countries or North Africa. About 80% of the world’s wheat is winter wheat. Winter wheat is sown in autumn because the seedlings need a period during the vegetative phase when temperatures are between 0 and 5 ☌. Wheat can be classified according to when it is sown. ![]() adapted to different temperate environments. For example, there are more than 25,000 varieties of Triticum aestivum L. Wheat is able to grow in temperate, Mediterranean, and subtropical regions of the two hemispheres, mainly due to its enormous genetic diversity. Its domestication is thought to have occurred in the Fertile Crescent about 10,000 years ago and has spread to all parts of the world through the first farmers, adapting the domesticated populations to different environments. ![]() ![]() From the most primitive form of wheat to the species currently grown, these and other desirable characteristics have been selected and developed by human societies since ancient times. Wheat is a high-yielding crop that is easy to store and is very adaptable to different climates. ![]()
