Title

Control of Seed Respiration and Growth in Vicia faba by Oxygen and Temperature: No Evidence for an Oxygen Diffusion Barrier

Ries de Visser; Harold M. Dekhuijzen; Dick R. Verkerke PLANT PHYSIOLOGY 1990. doi:10.1104/pp.93.2.668

Other claims from this paper (10)

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.
