Question on Moss Activity

	I'm trying to measure fluorescence and thermoluminescence on
different moss species. The first results gave me strange trends :

- for fluorescence, I've got a variable fluorescence for one specie
(pleurozium schreberi), but not for the other specie (scleropodium
purum). Can you explain this ?

I guess it's because the PS2 doesn't give electron to QA...

- for the thermoluminescence, both species present small
thermoluminescence for small temperatures, but it increases a lot for 70
to 100 degree (C). Again, can you explain that fact ?

Perhaps this is a stress reaction ?

Thank you,

David Gross
