Abstract

Flowering and pollination of Arceuthobium pusillum growing on Picea mariana were studied in Carlton County, MN. Staminate flowers opened in April and abscission was complete by mid-June. Average number of pistillate flowers per aerial shoot ranged from 4.8-5.1. From the flowering period of seed dispersal (September), 36-59% of pistillate aerial shoots were lost. Based on March flower counts, 0.3-2.4 fruits matured per aerial shoot, ie 5-35% of pistillate flowers developed into mature fruits. Although insect exclusion studies demonstrated that wind pollination did occur, few grains of Arceuthobium pollen were collected with vaseline slides or a Rotorod sampler. Fifty-nine species of insects trapped on sticky-board traps carried pollen of Arceuthobium. Entomophily is the most important pollination mechanism for this dwarf mistletoe. -Authors
