No. Corn reproduces from a process called "Silking". It begins when any silk is visible outside the husk on the stalk. Falling pollen grains are captured by the silk and grow down the silk over a 24 hour period ultimately fertilizing the ovule. The ovule becomes a kernel. It takes upwards of three days for all silks on a single ear to be exposed and pollinated. The number of fertilized ovules is determined at this stage. If an ovule is not fertilized, it will not produce a kernel and it eventually degenerates. Each kernel can be dried and replanted to reproduce another plant. See the related link for more information.
