Title
Light-enhanced Chloride Uptake by Wheat Laminae
Ian R. MacDonald; Alan E. S. Macklon PLANT PHYSIOLOGY 1975. doi:10.1104/pp.56.1.105
Other claims from this paper (8)
- Intervention effect A light-enhanced uptake of chloride developed after a few hours in wheat leaf segments.
- Intervention effect In whole water-infiltrated laminae, light-enhanced chloride uptake was apparent from zero time.
- Observation Chloride uptake values achieved in the light were similar in the two tissue types.
- Observation In the dark, chloride uptake by whole infiltrated laminae was restricted.
- Mechanism The authors consider that the slower dark uptake by whole laminae relative to chopped tissue is due to cuticular resistance to solute penetration.
- Mechanism The authors consider that in the light the impediment to uptake is overcome by stomatal opening.
- Observation A light-enhanced chloride uptake unrelated to stomatal opening was discernible in both tissues.
- Intervention effect The chloride absorption mechanism was not impaired by vacuum infiltration.
