Answer:
none at all
Not true.
The anther of a corn plant is at the very top. The anthers, attached to their filament, make up the stamen. The stamen produce pollen. The silk on the ear of corn is the pistil, made up of a stigma, a style, and an ovary. Each thread of silk is attached to an ovary (potential seed), which will develop into a kernel of corn. The pistil must receive some pollen from the anthers in order to fertilize the ovary and make a kernel of corn. Without the silk (pistil), there would be no kernel. Removing all of the pistils from an ear of corn will result in no corn on the cob.
