4th attempt, day 3.....
From the same DIGNITY DANCER seedling. I was curious to see if there
was any pink pigment (no). Also wanted to see distribution of yellow
pigment(s).
The photo in this post was after the <first> extraction/soak in hot
isopropyl alcohol. I was surprised at the blotches of blue pigment
around the edges of the falls and standards that didn't come out in hot
alcohol.
Also by how much blue (?) pigment remained in the veins even after
following the alcohol soak with a good long soaking in very hot water
(photo in previous post). More aggressive hot water/alcohol got rid of
some of the pigment shown in this photo, but there is still more than
I've seen in any blue pigmented petals after extraction.
This is the second attempt at extraction - the first gave similar
results - very dark veins - but it had more blue and shriveled up before
I got a good photo.
Could the dark pigment resistance to extraction be a result of exposure
to cold? Or is this some of the little black do-hickeys (AVIs?) Or is
the blue pigment harder to extract from petals and even more so from
veins of blooms with heavy substance?
Or is the green color in veins maybe actual green pigment instead of
blue plus yellow, with maybe heavier concentration of veins at the rim?
[Betty, was it worth the wait? Took about 4 attempts over 4 days before
the last one went thru. :-( ]
