Abstract

For successful reproduction animal pollinated plants must provide resources for both pollinator attraction and offspring production, and theory suggests that resources and pollen delivery limit reproduction simultaneously. We conducted a series of experiments involving supplemental pollination, flower removal, fertilizer addition and foliage removal to investigate the interaction of resources and pollen on fruit-set of Aciphylla squarrosa, a long-lived, dioecious, masting herb in Wellington, New Zealand. Reducing floral display decreased open-pollinated fruit-set, suggesting that display size is a reflection of an optimal investment between attraction and fecundity. In combination with suppl..
