The cornhusk is part of the corn's filament, the female flower of the corn. Without the cornhusk, the corn plant would not produce corn. Corn is a monoecious, cross-pollinated plant, with the male flowers growing at the top of the stalk and the female flowers growing in the middle of the stalk. Corn pollen is spread by the wind, the wind spread the pollen of the stamen to the pistil, so that the pistil pollination will soon develop into corn seeds, and the filament will lose its role as a corn "beard". When the corn blossom pollination time, due to the impact of bad weather, it is also possible that the pistil does not get enough pollination, so it will cause the phenomenon of corn grain shortage.
