I conducted a field study of the annual, Clarkia unguiculata, to examine the performance of pollen (pollen-germination time and pollen-tube growth rate) produced by plants growing in two different environments: recently burned and unburned oak woodland. Previous studies on the effects of fire on soil nutrients demonstrate that burning increases the levels of plant nutrients (e.g., phosphorus, potassium) in the soil, which may influence the performance of pollen from individual plants growing after fires. This study addressed three questions: Do plants from burned environments grow more vigorously and taller than plants from unburned environments? Do pollen-tubes from plants growing in recently burned environments grow faster than pollen from plants growing in unburned environments? Is pollen performance related to plant vigor (height)? Plants growing in burned environments were taller than plants growing in unburned sites. Pollen-tubes from burned-environment individuals grew faster than pollen-tubes from unburned-environment individuals. Overall, there was a positive relationship between pollen-tube growth and plant height. These results suggest that, by affecting pollen performance, fire can influence a plant's ability to compete for the fertilization of ovules.
