[0038] Effect of water on the growth of oats: Oats grow in high-altitude desert areas, but seeds need about 65% of their own weight in water when germinating. The transpiration coefficient is higher than that of barley and wheat, and the water consumption is also relatively high. If there is insufficient water during the growth period, the grains are often not full and the yield is reduced. Therefore, the rhizomes of oats are often about one meter long so that they can absorb more water.
