Salut Marc,

seed bank, c'est bien ce que tu veux dire (conservatoire de graines) ?

Hello,

see if these help you

Episodic Bryophytes in the Diaspore Bank of a Zimbabwean Savanna. Heinjo J. During. Lindbergia Vol. 32, No. 2 (2007), pp. 55-61.

My direct experience is with Riella spp. , not quite the same as you intend. We used to mix sediment after a dry period with distilled water (30 gr. in 300 ml.), leave it to room temperature and refilling when necessary.  We got mature plants very easily.

Best of luck,

Marta

Dear Marc,

Put the sediments under light and keep it wet in a way to imitate the in situ condition. Make sure that the air humidity is constantly high and that the sediments is not dried out during all the period. I do think at least some spores will germinate to protonemas and will pass to gametophores. I have good experience with this way, 16/8h light/dark and the temperature 18C, with humidity above 60%.

Best,

Marko

Dear Marc,

Have a look at this if it may be of any help, though done in a tropical wet ecosystem / forest.  https://www.researchgate.net/publication/301201574_THE_ROLE_OF_Psidium_guajava_L_SEED_BANK_AS_A_STRATEGY_FOR_ITS_SUCCESSFUL_INVASION_OF_KAKAMEGA_RAINFOREST_WESTERN_KENYA

For bryophytes you have a SPORE bank, not a seed bank!

A diaspore bank not a seed bank....

your research study should be based on formation and dispersal of spore season in bryophytes. 

Thank you all for your answers

"seed bank" is indeed a common locution to refer to the diaspores (seeds, spores, fruits, propagules, etc.) which can be found in a soil. As for Bryophytes of course this is limited to spores and propagules.

Bonjour
