Every individual Apis mellifera collected foraging on Prunus armeniaca blossoms had self-pollen on its body and 90% or more had cross-pollen. In 1988, 60-92% of the foragers had non-almond pollen on their bodies, while in 1989 the percentages were 92-100%. In 1988, 42.1-81.2% of stigmas examined had self-pollen, 36.8-68.7% had cross-pollen, and 43.7-94.0% had non-almond pollen. In 1989, 60-100% of the stigmas had self-pollen, 10-100% had cross-pollen, and 80-100% had non-almond pollen. Nut set on limbs adjacent to compatible pollen sources did not differ significantly from those within the same row adjacent to trees of the same cultivar (ie incompatible pollen sources). -from Authors
