- Intervention effect The rate of dry matter accumulation by Vicia faba cv. Minica seeds increases with temperature between 16 and 26 degrees C.
- Intervention effect The duration of seed dry matter accumulation decreases with temperature.
- Intervention effect O2 uptake rates of intact seeds in buffer were only 9 to 15% of those in air.
- Intervention effect In buffer, the respiration rate of intact seeds decreased at a pO2 below air saturation (21 kilopascals).
- Intervention effect In buffer, separated seeds showed a decline of O2 uptake only below 80% of air saturation.
- Intervention effect In air, embryo excision had no effect on the sensitivity of seed respiration to pO2 at both 20 and 26 degrees C.
- Intervention effect In air at 20 degrees C, separated and intact seeds showed similar rates of O2 uptake.
- Observation Oxygen uptake by intact seeds, both halfway and beyond the linear growth phase, showed a temperature coefficient Q10 of 2.3.
- Observation Oxygen uptake by intact seeds was insensitive to pO2 in the range of 80 to 100% of ambient.
- Mechanism The results indicate that V. faba seed respiration in air is not limited by the diffusion of O2 into the seed.
