Corn tasseling refers to the stage when the corn plant produces its tassel, which is the male part of the plant at the top of the stalk. The tassel contains hundreds to thousands of spikelets, capable of producing the pollen needed for fertilizing the silks on the ears below. The tassel's job is to shed pollen, which is carried by the wind to the silks (female parts) on the ears of the corn. Successful pollination leads to kernel formation and, ultimately, an ear of corn.
