Measuring Conifer Needles Using the CI-340:
The CI-340 does not have specific conifer or needle chambers as opposed to chambers for broadleaves. The type of
chamber selected for measuring conifers will depend on the plant type (average needle length and other characteristics).
The LC-4 and LC-5 small and large cylinder chambers, respectively, are recommended for measuring small
leaves/leaflets or needles still attached to the branch. Both chambers are specially designed with an opening that
provides for a branch to fit into the chamber (and extend through it) while still sealing. The orange section of the seal is
double-lined, approximately 7 mm thick, and has small slits allowing it to expand and accommodate the shoot going
through the chamber.

The LC-1, LC-2, and LC-3 chambers may also be suitable for gathering measurements from conifer needles. However,
these chambers do not allow for an entire branch to pass through the chamber. If the plant has characteristically long
needles (longer then the LARGEST side of a plant chamber) then the needle or needles can be manipulated to extend
across the chamber and be sealed on both sides. Several needles can be lined up next to each other to increase the leaf
area being measured inside the chamber. It may be easiest to remove the needles to be measured from the plant, but if
this is not an option then using the branch and cylinder-type chamber would most likely be best.
