PHOTOSYNTHESIS, TRANSPIRATION AND STOMATAL CONDUCTANCE

The closed system environment deals with chambers of variable volume. Each individual chamber is

designed to interchange with the CI-340; however, they serve different sizes of the plant element.

There are four available sizes of leaf chambers to conduct experiments for the closed system method

(Table 7-2). Generally, the manufacturer recommends choosing a chamber large enough to contain

the leaf environment (i.e., using a leaf larger than the chamber area would produce inaccurate results).

When using the closed system, refer to Table 7-2 for such related values. Also, refer to the LEAF

CHAMBER —CARE AND USE chapter for proper applications of the leaf chamber. Press the

and key(s) to begin the measurement process. The duration of collecting

measurements is dependent upon the needs of the user.

Table 7-2. Closed system chamber sizes:
