Method synopsis

Standardized protocol for determining dry mass of plant tissues through controlled oven drying at 60°C for 48 hours followed by precision weighing to calculate dry matter content and mass ratios.

Synthesized from method descriptions across 4 papers using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Caloric content of Rocky Mountain subalpine and Alpine Plants (1976), Journal of Range Management. Implementations in other papers (listed below) may differ.

1. Oven-dry samples
   Prior to calorimetric analysis, samples were oven-dried to remove remaining moisture
   Quantities: All samples processedDuration: At least 7 daysConditions: 60°C oven temperature
   Equipment: oven
2. Grind samples
   Subsamples were prepared for analysis by hand grinding to ensure uniform particle size
   Quantities: Subsamples from each specimenDuration: As needed for each sampleConditions: Manual grinding process
   Equipment: mortar and pestle
3. Determine caloric content
   Ground samples were analyzed for caloric content using bomb calorimetry
   Quantities: Individual measurements for each species/plant part combinationDuration: Per manufacturer specificationsConditions: Laboratory conditions
   Equipment: Parr 1411 semimicrocolorimeter
