WebThe ear IM grows and forms primordia, which become the spikelet pair meristems (SPMs), which in turn develop into spikelet meristems (SMs). Each spikelet meristem produces floral meristems (FMs), which determine the number of kernels in the ear. The kernel row number of maize is therefore determined by the number of SPMs in each ear.
