Hi Marika! The last pic is of a test tube that contains liquid growth medium (Nitsch and Nitcsch), plus some BAP, 2,4-D, maltose and sucrose along with some anthers from Papio Shelli Mae (which I mispelled on the tube).
As far as I know, no one has anther cultured daylilies to convert tets to dips, or dips to haploids, so I'm unsure if my hormones, nutrients, etc are optimal, or even if it's possible. Some plants can be anther cultured and some can't.
So far, no growth in the test tubes. And, I've had a dickens of a time with fungal contamination ruining about half of my attempts.
