Hybridizing. — Saving Pollen.
We have numerous accounts on record of seeds having vegetated after long periods of rest, away from atmospheric changes, after being boiled for different lengths of time, and after resisting the pestilential influence of sewer and soil-drains for many years. Plants have been raised from seeds which ripened in the herbarium of the botanist, and remained there for a lifetime; and there is hardly any other way of transmitting the seeds of Ferns from one country to another than that of cutting off specimens, or pieces of the Fern-leaves, before the seeds are quite ripe, to dry them, and then pack them where no moisture will reach them, and they are safe for many years, the dust-like seeds of Ferns being even more tenacious of life than the larger kinds of seeds; but to retain its power, it must be in the seed-vessels, and on the leaf which bore them, and the leaf must be gathered and dried like hay, before the seed-vessels are ripe enough to open and discharge the seeds.
In the same way, and under similar circumstances, we have presumptive evidence that pollen may be gathered, and harvested so as to retain its subtle power of impregnation for any definite period, or, at least, as long as Fern-seeds retain their powers to vegetate. This is a new field of inquiry into which we would lead the young gardener and the amateur.
I have not tried this technique, but I'm inclined to think that Beaton would not have risked his reputation on something that didn't work.
Here are some other of his discussions of stored pollen:
