Hi Stephen:

They aren't cheap, but see if anyone has a Pulse Amplitude Modulated
Flourometer (PAM) you can borrow.

Greetings to all listserv members,

  In case I cannot find a spare LiCor 6200 leaf chamber I thought I'd post
to the list a couple of related ideas / questions.

  What sort of low budget methods are available to at least qualify, if not
quantify, the presence of photosynthetic activity?

  Are there any diagrams available to describe the construction of a leaf
chamber such as that of a LiCor 6200?

  Thanks to all in advance

  Sincerely Stephen Johnson
