Making Seeds at Home – Part Two

Step Four: Store pollen.
Store small amounts of pollen in aluminum foil, enclosed with silicon to absorb excess moisture so that it does not destroy the pollen. Pollen has a short shelf life in nature. High temperatures and moisture destroy it. Pollen can be stored in the freezer for several months. Store pollen in an airtight container along with silicon pellets to absorb any moisture in the container. Periodically remove silicon to dry and then be returned to the container. Make sure to let container sit at room temperature for several hours to avoid moisture condensation from temperature change. Carefully remove pollen from the collection bag and pass it through a screen to remove flower remnants. Remember, dead flowers and foliage attract moisture and will contaminate and spoil pollen. Place wax paper under the screen to catch pollen. Pour pollen into a sterile test tube or small container from a craft store. Scrape remaining pollen into tube or container with a sterile instrument. Seal test container. Put test tube in a larger airtight container with several packets of silicon to absorb moisture. Seal pollen with silica gel and leave at room temperature so the silica draws moisture from pollen before putting it in the freezer. At pollination time, pull pollen out of freezer and let it warm up to room temperature. Do not open the container when cold or water will condense inside and kill the pollen. Keep refrigerator at low humidity. Thawing and refreezing pollen will diminish its viability. [caption id="attachment_8576" align="alignnone" width="800"]
Step Five: Pollinate female.
Flowering females grow many ready, receptive stigmas until pollination occurs. Best pollination takes place about 3 to 5 weeks after females show their first flowers. At this point the majority of receptive stigmas are ready for pollination. This is when a few of the stigmas start to curl and slightly discolor, signifying the onset of senescence. Receptive stigmas are turgid and most often are white or off-white in color. Senescing and dying stigmas that are brownish are not viable.
