Joe is one of the most important crops in the world that humans and animals can be used as food. This herbaceous plant belonging to the family of grasses (grasses) are. And has cultivated and wild.
Barley crop species fall into three categories: six full, double-headed and four full weather. The plant was adapted to the wheat and in all areas of temperate and cold in many places comes into operation. Zarhayy in dry soil moisture and rainfall is insufficient for growing wheat, barley can replace it.
Joe Shoot Like other grasses, hollow and its height according to environmental conditions, between 30 and 120 cm. The stem is between 5 to 10 leaves are alternately arranged on the stem. Like other grasses, barley leaves, with sheath, blade, ligule and earrings. In addition to the photosynthetic activity pod, stem strength also plays a role.
Along the stem, the rachis. Ear of spikelets per spike and consists of a flower. Seed, the flower is formed. Pvshynk inner and outer florets, when the seeds stuck to it and picked apart even when they are not. When grain is gradually loses its moisture, its volume was low and the Chinese domestic Pvshynk. The amount of wrinkling, product quality atmosphere of the show, so that whatever China is more equally Pvshynk is thinner and better result can be this type of barley used in the fermentation industry (eg softer ).
Joe true origin is unknown. But many researchers, the origin of the plant in West Zagros Mountains of Iran, southern Anatolia and Palestine know. Based on the theory Valyvf, awn barley origin and sheathed, Ethiopia and North Africa Source type without awn, awn short and lockable caps, Southeast Asia, especially China, Japan and Tibet.
Search for a lot of people cold and dry areas (especially the Middle East and North Africa) is an important food source. Today, more for animal feed and the preparation of fermented products from this plant use.
Barley grain is one of the most consistent in terms of good weather, fertile soil that is high water retention capabilities, as well as in soils pH is between 7 to 8 generated. It is more drought tolerant than wheat against climate so that the water would be limiting the production of cereals, barley can produce more product. In dry conditions better than wheat, barley and rye are also performance. Barley production in all types of terrain with annual rainfall of 200 to 250 mm possible.
The atmosphere of high temperatures (over 32 ° C) resistant. But the wet weather, is very sensitive to high temperatures.
Barley than wheat requires less moisture to germinate. In cases where the seed germination, plant due to lack of moisture to dry, providing favorable moisture conditions, plant growth begins again with more intensity.
Search for resistance to cold than wheat is placed in the lower row. So it seems that winter barley cultivated in cold regions is not very reassuring.
Compared to other grains, barley to salinity, and other processes in the germination stage is more resistant.
