Thermoluminescence (TL) is a technique consisting of a rapid cooling followed by the progressive warming of a preilluminated sample to reveal the different types of charge pairs as successive emission bands, which are resolved better than the corresponding decay phases recorded at constant temperatures.

Title : Photosynthesis limitations during water stress acclimation and recovery in the drought-adapted Vitis hybrid Richter-110 ( V . berlandieri x V . rupestris )
1 Grup de Recerca en Biologia de les Plantes en Condicions Mediterrànies, Departament de Biologia (UIB-IMEDEA). Universitat de les Illes Balears. Carretera de Valldemossa Km 7.5, 07122 Palma deExpand
Photosynthesis limitations during water stress acclimation and recovery in the drought-adapted Vitis hybrid Richter-110 (V. berlandierixV. rupestris).
A photosynthesis limitation analysis revealed that diffusional limitations and not biochemical limitations accounted for the observed decline in photosynthesis during water stress and slow recovery after rewatering, both in moderately and severely stressed plants. Expand
Characterization of the chlorophyll thermoluminescence afterglow in dark-adapted or far-red-illuminated plant leaves
It is concluded that thermoluminescence can give original information on the photosynthetic mechanisms in whole leaves, provided that harmful effects of extreme temperatures are avoided. Expand
Remote sensing of sunlight-induced chlorophyll fluorescence and reflectance of Scots pine in the boreal forest during spring recovery
A measurement campaign to assess the feasibility of remote sensing of sunlight-induced chlorophyll fluorescence (ChlF) from a coniferous canopy was conducted in a boreal forest study site (Finland).Expand
The Origin of115–130°C Thermoluminescence Bands in Chlorophyll‐Containing Material
High‐temperature thermoluminescence (TL) emitted in the temperature region from +50 to +150°C has been studied in a variety of chlorophyll‐containing samples that were allowed to dry during the TLExpand
Heat stress induces in leaves an increase of the minimum level of chlorophyll fluorescence, Fo: A time-resolved analysis
It can be inferred that heat determines an irreversible disconnection of a monor antenna complex which is not the LHC IIb complex, this effect is induced by temperatures higher than 40°C and a decrease of the quantum efficiency of Photosystem II photochemistry which is due to several effects.

Increased heat sensitivity of the photosynthetic apparatus in triazine-resistant biotypes from different plant species
Etude des effets de courtes periodes de stress thermique sur les proprietes structurales et fonctionnelles de l'appareil photosynthetique de plantes resistantes a la triazine
Thermoluminescence: experimental
In the present review, instruments and the experimental procedures for measuring thermoluminescence emission from photosynthetic systems of various origins are summarized and discussed. Expand
Effects of dark- and light-induced proton gradients in thylakoids on the Q and B thermoluminescence bands
Thermoluminescence provides direct evidence on the enhancing effect of lumen acidification on the S3→S2 and S2→S1 reverse-transitions. Expand
