Forced Germination - preparing onco seed
Mini bulb lover:
I have some more Onco seed (Iris kirkwoodiae) to try so I thought I'd share some photos of them being cut today. The top seed in the 3rd photo moved as I sliced so it cut more than I wanted. I'll see how I go.
Jupiter:
Jon, how are your kirkwoodiae seeds looking? Any sign of movement? I'm going to do some soon as well.
Véronique Macrelle:
the 2020 srgc exchange being canceled (hopefully it will resume next year!) I find myself without iris seeds to sow this year.
your discussion made me want to give it a try. and so my idea was to sort out my pots of iris seedlings from a previous year that did not germinate:
I thus found 4 beautiful seeds of Iris paradoxa. (I occupy my confined winter Sundays as best I can!)
I have some questions:
- is it essential to sterilize the seeds and the substrate?
- can we sow directly in a gravel pot? without going through the 'perlite in plastic bag' phase? I have always missed this type of sowing with Trillium or Paeonia: too wet or I handle them too much, eager to see changes ... too curious
Véronique Macrelle:
in fact if it should germinate it does not take long: it's too funny!
I steam sterilized everything.
I also cut some on the wrong side because on these old seeds the arill was no longer visible.
I have one that started in 2 days!
the others I cut back, and 2 are already starting .. but the end of the root is truncated, so I doubt the result.
the last one (I had 4) seems to be cut off on the wrong side, it doesn't move
and once we have a germination, what do we do with it?
hot, cold, fertilizer, artificial light?
i fat germinated it directly in aquarium gravel, but it can't feed
