Nectar samples were harvested daily from exposed and caged portions of the low-bush blueberry, Vaccinium angustifolium (varieties laevifolium House and nigrum (Wood) Dole). Pollination activity on the exposed bloom had no significant effect on mean nectar volume and concentration but caused a slight reduction in the mean weight of nectar sugar. Nectar volume and weight of nectar sugar increased directly with the age of inflorescence in all clones.
