The emergence of at least one strand of silk from a given ear of corn is defined as growth stage R1, and the emergence of silk in 50% of the plants in a corn field is called "mid-silk". The silk lengthens from the basal ovules during the 10 to 14 days previous to growth stage R1; this is due to a change of shape of existing cells rather than their replication. The elongation progresses at 1.5 inches per day at first but gradually slows as the full length is approached. Elongation of a corn silk strand stops soon after a grain of pollen is captured or due to

If an ovule is successfully fertilized, the corn silk will detach from it two or three days later. Otherwise, the silk will remain attached indefinitely, and fertilization remains possible (with decreasing chances of success) for 10 days after silk emergence. For this reason, it is possible to sample
