Macro pIcture of a sporophyte

Recommended Posts

Edit: This Sphagnum is Sphagnum fimbriatum, it's growing almost choked by surrounding S. palustre.

For the first time, i see sporophytes on some of my Sphagnum. The spore capsules are so small I barely noticed them. They grow on a thin species that ocassionaly manages to keep itself alive in a pot of a more robust species of Sphagnum. I think there are only 3 strands alive in that pot. I'm not sure but I assume the species is self fertile, i would be surprised if I had both a male and a female clone of that plant.

I'll try and germinate the spores, just as experiment. Would be nice to see the moss develop, but I'm pretty sure it's not easy to make germaninate. Any tips are welcome!

Seems like a sporophyte isn't long-lived. Only two days after I noticed, some of them have already exploded and dispersed their spores.

Really interesting, could you keep updated the development?

Fantastic, never seen anything like that before.  Thanks for sharing.

Update: I sowed the spores in two different conditions on peat. I cooked the peat for 10 minutes. I have germination in one of the pots, but I'm not sure if it's from the Sphagnum spores I sowed, or from spores that didn't die. This pictures shows protonemata from what I hope to be a Sphagnum. Google images isn't really helpful on how they should look like. If anyone knows for sure what it is, let me know

WoW :woot:

Some seriously good photography skills you have!

Very interesting to see the development so far :yes:

Thank you all for the kind words. Update: A lot of the protonemata are dying or becoming white instead of green. I'm not sure what's wrong, maybe I should try to put them in higher light, they are quite shady at the moment. But quite a bit of them have formed gametophores (Adult moss plants). They are still really young and I don't see any resemblence with Sphagnum yet, but I'm almost 99 pcnt sure it should be Sphagnum. I'm really curious to see how it keeps developing.

This is a really short, but amazing video showing the spore ejection from sphagnum. It was apparently a mystery how they got the spores so high, until they filmed it at very high speed and saw that the capsule actually developed a vortex ring, and with that could send the spores much higher than just a straightforward squirt.

Crazy, I wonder how complex the inner structure of that capsule has to be in order to reach this effect. The explosion of the capsule on itself is already impressive. Funny what big efforts this tiny plant has to do to ensure its existence and reproduction.

Hey Folks,

I found this this morning...... Informative about the power of a vortex ring!......

Now, to gather billions of sporophytes and blast them away with one of those cannons... I'm sure they'd appreciate the help.
