- Notes:
- Exact root diameter not listed, expected to be less than 2mm maximum diameter Immediately after harvesting, root segments were cleaned using a camel-hair brush, and then oxygen consumption was measured using a polarographic oxygen sensor(Yellow Springs Instrument Model 53). During the oxygen consumption measurements, root segments were immersed in 3 ml of 10% Hoagland's solution adjusted to pH 6 with Na2HPO4. Oxygen consumption at 25, 18, 12, and 5° C was measured following a 30 min equilibration period at each temperature. All measurements were completed within 3 h from time of harvest.
