avidly collecting exposed pollen mass
of the dehisced anthers of a 2nd day flower.
After thein cubation period, pollen viability was analyzed by observing the staining of pollen mass
in an optical microscope under a10x magnification.
The pollen mass
was drawn into a band, and the total number of pollen grains was counted under a compound microscope (40x objective, 10x eye piece).
When a bee lands, brushing the flower's long trigger hairs, a floral structure slams a pollen mass onto the bee's back.
Its power comes from the sudden release of a bent strip of tissue, called a stipe, attached to the pollen mass, Fulop reported July 27.
The pipettes were loaded by pressing the tip into the sticky pollen mass
at the bottom of the Eppendorf tubes.
The pollen mass (pollen + oily substance) contained a hollow, sometimes divided by a transverse ridge, on the exposed face of the pollen mass.
The pollen mass has a hollow area, sometimes divided by a transverse ridge, on the exposed face of the pollen mass, The egg was in a vertical position in the lower part of the hollow (Fig.
First, we assume that the pollen mass occupies a limited region on the pollinator's body and that the sexual organs of flowers contact all areas of this region with equal probability.
Second, we simplify the multilayered pollen mass to only three functionally different layers: top, shallow and deep pollen [ILLUSTRATION FOR FIGURE 5 OMITTED].
i], respectively) and immediately after the anthers add pollen to the pollinator's pollen mass ([T.
3, Lertzman and Gass used a stochastic simulation approach, which allowed them to incorporate the complexity of variation in anther and stigma contact (resulting in a pollen mass with a bivariate normal, rather than wafer, shape) and to account for as many layers as necessary.
