At non iris meeting, the speaker (a large commercial rhododendron grower)
mentioned they are using colchicine to improve rhodies. I asked him if they
were treating the seeds and the answer was no. All their propagation is via
tissue culture and they treat the tissued sprouts and looked for changes and
improvements as they grew the plant on.
Is this a new time in the plant cycle that could be adapted to Iris and
other perennials? Would you treat as the roots germinate or as the leaves
are at certain stages? No idea what % solution would be needed. Don't think
it would need to be as strong as for seed treating as you would not be
dealing with the seed coat. What about treating rhyzomes?
Maybe some is already doing this but I have only heard about soaking the
seeds.
