germinating fern spores
The slide already bore an overdose of dry spores used for previous inspection. Then I kept it for about a week in a petri dish with a layer of water.

Re: germinating fern spores
They definitely grow much slower in the petri dish than on earthy media where they already developed small sporophytes. I doesn't help, I suppose, that there are hardly any nutrients available. For a long time they remained uniserial (all the cells in a single row), but now several are making lateral divisions too. This results in an elongated triangular shape with the spore-rest at the top, foreboding the typical heart-shaped form of the gametophyte. Perhaps the low light made them longer then usual?ImperatorRex wrote: ↑Thu Jul 29, 2021 3:42 pmReally great, without any doubt! Thanks for sharing...

I found one that's already 3-4 cells wide:
