Spruce Allergy Info
Members of the pine family pollinate profusely, contributing large numbers to pollen counts. However, they are rarely considered a particularly allergenic pollen.
Spruce Pollen Description
Pine grains are large due to their sacs or bladders, which make them one of the easiest pollen grains to identify. These sacs also allow them to be carried great distances by the wind. Among winged grains, the body is subspheroidal to broadly ellipsoidal. The bladders are generally reticulate or occasionally smooth.
Picea pollen grains can be as large as 160 micrometers.
