Quantities measured during plant calorimetry

Calorespirometry measurements of animal tissues, cell cultures, and microbial populations have typically been made in perfusion calorimeters or flow calorimeters [23-25]. Flow methods allow continuous monitoring of input and output materials as well as heat and gas fluxes. However, flow systems often do not work well with most plant. samples. Plant cell cultures commonly clump badly, interfering with the mechanics of the perfusion process. Marine plants. 

The final required measurement for most plant calorimetry is tissue mass. Commonly both sample fresh weight (g FW) and dry weight (g DW) are determined. Dry weights are obtained after drying in a vacuum or convection oven at 75 to 85 C for at least 24 hr.
