“…Therefore, pigment system II is usually relied upon for analysis of stress in plants (Epitalawage et al 2003). Chlorophyll a (chl a) fluorescence, produced by the chl a molecule after excitation by light, is a noninvasive and rapid biomarker for the assessment of stress (microbial and environmental) effects on PSII, as well as its structure and function Tsimilli-Michael & Strasser 2001, Epitalawage et al 2003Lange et al 2004;Goltsev et al 2005;Strauss et al 2006).…”

We applied chlorophyll a fluorescence as a biomarker to assess the growth enhancement of maize plants after inoculation with the mycorrhizal fungi Piriformospora indica, Glomus mosseae, or a mixed culture (P. indica, G. mosseae and G. caledonium), and compared it with uninoculated plants (controls). The quantum efficiencies for pigment system II (j Po) were not much affected. The yield for electron flow (j Eo ¼ j Po * co) was highly responsive to P. indica and mixed culture. Electron transport per trapping center (co) was remarkably influenced by the endophytes. Plants treated with P. indica and mixed culture showed relatively higher quantum yield compared to uninoculated plants. Absorption per reaction center was influenced by the endophytes. Piriformospora indica followed by mixed inoculum showed slightly lower values as compared to controls. The morphological markers, namley height of the plants and percentage colonization in the roots, reflected the biophysiological markers (chlorophyll a fluorescence); hence, the JIP test (a test applied to analyze fast fluorescence kinetics O-J-I-P) can be used as a sensitive and rapid tool for determining the efficiency of mycorrhizal fungi in host plants.

“…C 2 -chlorocarbons are readily absorbed in the cuticle and any membranes of cells containing lipids and wax substances, from where they can be distributed to mesophyll cells or be desorbed again Frank 1986, Figge 1990). Lange et al (2004) found that the phytotoxicity of similar TCA concentrations in pine needles depended on the assimilation pathways of TCA in the plant. TCA translocated into the spruce needles via the soil/root pathway displays milder phytotoxic effects than comparable amounts of TCA formed in spruce needles after atmospheric PER exposure.…”

Trichloroacetic acid (TCA), a secondary atmospheric pollutant, is also formed in forest soil and thus ranked among natural organohalogens. The observed biooxidation of atmospheric tetrachloroethene (PER) to TCA in chloroplasts has led to the investigation of the mode of action of TCA in spruce needles, since TCA is also accumulated in the needles after its rapid uptake from soil by roots. Being phytotoxic, TCA considerably influences conifers by affecting their photosynthetic apparatus. We examined the transport of TCA from soil into chloroplasts in order to compare the effects of TCA on conifers from both sources, i.e. endogenously produced within chloroplasts or taken up by roots. The influence of TCA formed in chloroplasts was found to be much more adverse than that of "soil" TCA.

“…It has been widely and successfully used for the investigation of PS II behavior in various photosynthetic organisms and enables the study of synergistic and antagonistic effects of different co-stressors (Lange et al 2004;Strauss et al 2007;Smit et al 2009;Lange, Böcker, and Katzur 2011).…”

Rehabilitation of mine tailings dams is often a challenge due to a lack of nutrients and a poor humus reservoir prevailing in tailings soils. This is especially true for establishing longer lived species such as trees. For these reasons the effects of different soil ameliorants (woodchips compost, vermicompost, mature sewage sludge), added to the root system of Karee (Searsia lancea) saplings were tested in pot trials. Those pots were filled with platinum and gold tailings substrate as well as red clay soil, respectively. For three months plants remained in a greenhouse and were subsequently moved to a test field outside. Throughout the test period regular chl a fluorescence measurements were taken and subjected to JIP-test quantifying changes in photosynthetic vitality status. Additionally, growth measurements and one-off leaf analysis were carried out. Test plants growing on mine tailings experienced an up to 35% higher average photosynthetic vitality (PI(ABS)) and improved nutrient supply, when treated with mature sewage sludge. Consequently, sewage sludge treated plants showed a higher biomass build-up rate and an up to 55% higher diameter growth, compared to control. In summary the experiments present a low cost alternative for reforestation enterprises on platinum and gold tailings dams in South Africa.
