Exploring with Wisconsin Fast Plants, by Paul Williams. Westmark Dr., Dubuque, IA 52002. Seeds are available from Carolina Biological. On plant cross-pollination 1. Use a cotton swab to collect pollen from open flowers.
Pollen grains give the anthers a dusty appearance when the anthers have released pollen.
Load the cotton swab with pollen from one plant. The swab will become yellow as pollen is collected. Using a different plant, pollinate the stigma in the flower by touching with the swab. You can see pollen grains on the stigma after pollination. Continue to cross-pollinate all open flowers on every plant.
