Whole Leaf Thermoluminescence Emission in Pisum Sativum L.: Influence of Leaflet Age
- 1 Lasers Department, INFLPR, Bucharest-Magurele, Romania
The thermoluminescence signals from leaflets of the same pea plant varied gradually according to their developmental stage. The AG emission, due to a back flow of electrons towards photosystem 2 (PS2) along a cyclic/chlororespiratory pathway, was stronger in mature leaves than in the growing ones. These age-related variations could be explained by a higher capacity of cyclic electron flow in mature leaves.
Additional key words: "afterglow" emission; pea; photosystem 2
