Cstem diameter at the base only
Ddry weight, which excludes water content
Answer & Solution
Correct answer: D. dry weight, which excludes water content
Fresh weight varies with how much water the plant has absorbed in the last few hours.
Dry weight, measured after oven-drying, reflects actual organic matter accumulated.
Length, area, and volume are also used but dry weight is the most reliable.
