Figure 2. Survival of creeping bentgrass pollen exposed outdoors. Pollen, collected within 15 min of anther dehiscence, was immobilized on traps made of feather down. Viability was assessed as germinability on an artificial medium. Each data point is the average of seven experiments, three replicate traps per time interval per experiment. Vertical bars represent standard error of the mean. The smooth curve is best-fit exponential decline equation: Proportion surviving = 0.6e(–0.036 x min).
