I found it in the 2008 Yearbook. WOW what a great set of photos!
You're absolutely right that details on the embryo extraction process
are what all the other articles fail to describe. One of them just has
a single sentence on it. LOL.
I just purchased a bunch of equipment (test tubes, forceps, scalpels,
funnel, etc.) to get me started but I haven't purchased any
agar/nutrient powders yet. Can you give me any suggestions? I'm mostly
doing spec-x crosses involving versicolor, and others with tectorum.
Oh by the way, if you grow yours in test tubes what size do you find
works best? I went with 1" x 10" since versicolor gets awfully tall
awfully fast.
Thanks, Ken!
