eems like yearly some fellow walks into the chat "n Chew Cafe delivering an odd-looking tassel the is part tassel and part ear to present off to the men over at the corner table. Much discussion constantly ensues end the causes of tassel ears, yet the usual agreement is the it drops into the general category of corny oddities and also is seldom a yield-influencing factor.

The male and female reproductive organs of a corn tree are consisted of in physically different unisexual flower (a flowering habit called "monoecious" for you trivia fans.) The tassel represents the masculine flower top top a corn plant, while the ear shoots stand for the mrs flowers. Interestingly, both reproductive structures initiate as perfect (bisexual) flowers, include both male and also female reproductive structures. Shortly after every each reproductive structure has actually initiated, the female contents (gynoecia) that the tassel and also the male materials (stamens) that the ear shoot abort, causing the unisexual flower (tassels and also ears) we involved expect.

Once in a while, part or numerous of the woman flower parts survive and develop top top the tassel, bring about individual kernels or partial ears of corn in place of part or every one of the tassel. The physiological basis because that the survival of the mrs floral parts on the tassel is likely hormonally-driven, but the eco-friendly "trigger" that transforms the hormonal balance is no known. Over there are also known genetic mutations that transform normal tassel advance by allowing the female flower materials to survive.

You are watching: What is the top of a corn stalk called

A "tassel ear" is one odd-looking affair and also is found nearly exclusively top top tillers or "suckers" the a corn plant follow me the edge of a field or in otherwise thinly populated areas of a field. That is an extremely uncommon to discover tassel ear on the main stalk the a corn plant.

Without a protective rice bowl covering, the kernels that construct on tassel ears room at the mercy that weathering and also hungry birds. Consequently, harvestable, great quality, serial from tassel ears is rare.

Some folks bump the tassel ear symptom right into the same classification as the malformed tassel symptom that the so-called "crazy top" disease. These two odd tassel symptoms are not associated and, in fact, look totally different. The "crazy top" an illness is led to by epidemic of young corn plants during ponding events by the soil-borne fungus Sclerophthora macrospora that eventually expresses chin by altering normal tassel breakthrough (and periodically ear shoot development) right into a mass of sheet tissue.
