Hello all,
It I were trying to germinate Honey Locust seeds, I think I would experiment with various ways of removing the seed coating entirely. I would try simple mechanical methods, using mechanical ways of gripping the seed and cutting or abrading the coating. I have it found it advantageous to save zinnia seeds while the seed coating is still green, and I can extract naked embryos using an X-Acto knife. I can remove naked embryos and get, in effect, zero day germination.
I use some auxiliary equipment to help me extract embryos from green zinnia seeds.
I have also used that technique on Milkweed seeds and Devils Claw seeds, with a reasonable amount of success. In the future I plan to experiment with a rotary tool like a Dremel and various grinding attachments. Milkweed seeds remain a challenge for me. I can extract their naked embryos easily enough, but they don't germinate well. I think they must need some cold treatment to stimulate the embryo growth.
