The sample was collected from this rose plant, north of North Mudd and south of Kerchoff, at 3:00 PM on May 10. Sample collection was performed by gently brushing the anthers of the plant while holding a sample slide underneath.
The pollen of the rose plant is visible as small yellow objects on the edge of the anther, as well as to the right of the anther. The image above shows pollen from a rose plant outside the north entrance of North Mudd, along with an anther from the same plant. The large yellow object is the anther, and the smaller yellow objects next to it, as well as the cluster of yellow objects to the right of the anther, are pollen from the plant. The sample was obtained by brushing the anthers of the rose while holding a glass sample slide underneath. A picture of the location of the rose is above.
There are many different species of rose, and I was unable to determine which species of rose the flower I found belongs to. The plant is in the genus Rosa, but the species is uncertain. Some questions I have about my image are:
What distinguishing features should I look for to be able to determine the species of rose?
Why does the pollen from the plant have the bright color that it does?
I may be able to answer the first question by performing further research on what specific characteristics define different species of rose, and I may be able to answer the second question by comparing this pollen to samples of pollen from other roses, other flowers, and other non-flower plants to find any significant similarities or differences.
