The rate of pollen dehiscence in a sweet corn ( Zea mays L.) plot was measured using a Rotorod Sample ® . Samples were taken from 0700 to 1230 h for 3 days during anthesis. Totals were averaged over the 3 days, and the resulting composite data were used to develop a sampling protocol accurate for determining the rate of pollen release. Results showed that a 10‐min sampling period, with a frequency of at least once every half hour was required to accurately reflect the pollen release rate.
