Other claims from this paper (4)
- Intervention effect Electron transport rate decreased by about 80% in Phaseolus vulgaris primary leaves during senescence relative to young, fully expanded leaves.
- Observation Photophosphorylation was coupled to electron transport in Phaseolus vulgaris leaves of all ages, with a mean P/2e ratio of about 1.3.
- Observation No evidence was found for inactivation of chloroplasts from older leaves during isolation or assay.
- Mechanism The decrease in non-cyclic electron transport may limit the rate of photosynthesis in senescing Phaseolus vulgaris leaves.
