In another post there was discussion of calcium aiding pollen tube growth, right?
So could we mix a little calcium in with sugar water, add some to a vial of pollen and shake it up, then brush the resulting pollen slurry onto stigmas? I wonder how long you'd have to do all your pollinations...30 minutes?
You could try making the solution be different pH levels, and try it on different types of roses.
It would be especially interesting on rugosas, I think. They are somewhat finicky about accepting modern pollen. It would be interesting if calcium (in what form?) or adjusting the pH of the pollen slurry would influence hip set.
Might as well dump in some ethyl methanesulfonate, too....just kidding, you chemists. Half kidding.
