| limits to reproductive success of sarracenia purpurea (sarraceniaceae). | plant biologists have an enduring interest in assessing components of plant fitness and determining limits to seed set. consequently, the relative contributions of resource and pollinator availability have been documented for a large number of plant species. we experimentally examined the roles of resource and pollen availability on seed set by the northern pitcher plant sarracenia purpurea. we were able to distinguish the relative contributions of carbon (photosynthate) and mineral nutrients (n ... | 2006 | 21642111 |
