Within minutes after putting the seeds in the 10% bleach solution, I saw streams of the pigment emanating. I had them in the solution for ~45 minutes and then I decanted the water and replaced it with new water. Since I could still smell the bleach, I left the centrifuge tubes open for evaporation. I also noticed that the seeds turned white, from the bleach. That alarmed me. I had them soaking in water for another couple days and then sowed them. Half went into the container I used for last batch and half went into an enclosed pipette container. We'll see what happens.
Another observation: The original crown on a seedling that has been comatose for the past 2 months, is all white and apparently dead. But strangely, it seems that another crown has replaced it. It is light green, but no leaves are as yet opened. Ever see that before?
