title: Fruit composition and patterns of fruit dispersal of two Cornus spp.
abstract: Fruiting phenology and pattern of fruit removal of two shrubby dogwoods were examined in relation to fruit composition. It was predicted that fruit of the species bearing high fat fruit would disappear more rapidly and fall to the ground sooner than fruit of the species bearing low fat fruit. Field observation at two sites in central Pennsylvania contradicts these predictions. C. racemosa fruit, containing relatively high concentrations of crude fat, were retained on plants longer and fell into fruit traps later than c. amomum fruit, containing relatively low concentrations of crude fat. A substantial portion of the crops of both species fell under plants and most fallen fruit were secondarily removed. Potential explanations for patterns observed in this study are discussed.
