• Additional comments: Since the total plant dry mass is required for leaf area ratio measurements, this is standardly measured only on young plants or plants grown for experiments where the entire plant can be harvested. It is best practice for leaf area measurements to include the petiole.
• units: mm2/mg
• allowable range: 0.05 - 100 mm2/mg
