Results/Conclusions We found evidence that basal cleistogamous flowers are made early in the life cycle, with plants producing buds at 5-weeks after germination, prior to production of chasmogamous flowers that produce aerial seeds. All maternal skeletons collected prior to germination in 2010 had basal seeds still attached (mean = 10.38 +/- 1.55 S.E.) regardless of maternal size. Basal seeds had high germination fractions in 2010 (mean = 0.35 +/- 0.03) and 99% survival prior to floral initiation. One month following germination, plants from aerial seeds are larger than those from basal seeds (one-way t-test, p = 0.029). Plants will be monitored for survival and reproduction throughout the 2010 growing season and collected following fruit maturation to analyze biomass allocation patterns and seed types made. Our preliminary data suggests that basal seeds provide reproductive assurance in a risky environment. By making these seeds early, while survival is still high, plants ensure that they have reproduced, even if they die soon after. These basal seeds also exhibit a conservative, slow growing strategy, compared with the more risky, aerially dispersing seeds. These results suggest that seed heteromorphism is a bet-hedging mechanism in P. heterocarpa, which reduces risk of reproductive failure and ensures representation in the next generation.
