Temperature Effects on Pea Plants Probed by Simultaneous Measurements of the Kinetics of Prompt Fluorescence, Delayed Fluorescence and Modulated 820 nm Reflection
Simultaneous in vivo measurements of prompt fluorescence (PF), delayed fluorescence (DF) and 820-nm reflection (MR) were made to probe response of pea leaves to 40 s incubation at high temperatures (25-50°C). We interpret our observation to suggest that heat treatment provokes an inhibition of electron donation by the oxygen evolving complex. DF, in a time range from several microseconds to mil...
متن کاملImpact of Salinity Stress on Photochemical Efficiency of Photosystem II, Chlorophyll Content and Nutrient Elements of Nitere Bush (Nitraria schoberi L.) Plants
Salinity is one of major stresses which can severely limit plant production, especially in the arid and semi-arid regions. The present study was carried out to evaluate the impact of salinity stress on some physio-biochemical parameters in nitre bush plants (Nitraria schoberi). Thus, an experiment was carried out under natural conditions and salinity stress was induced by a combination of diffe...

Interveinal chlorosis induced by iron deficiency is considered to be one of the problems in rose production in greenhouses all over the world. This experiment was conducted to elucidate the capability of chlorophyll fluorescence imaging technique to recognize early iron deficiency and also determination of relationship between leaf iron concentration and leaf chlorophyll content index and photo...
متن کاملThe Position of Carotene in the D-l/D-2 Sub-Core Complex of Photosystem II
When the sub-core complex of photosystem II, D1/D2, is irradiated at 436 or 415 nm (absorption by chlorophyll and pheophytin and ß-carotene) or 540 nm (absorption primarily by pheophytin), the low temperature fluorescence spectrum has two maxima, at 685 and 674 nm. This shows the existence of at least two different fluorescent forms of chlorophyll (chlorophyll a and perhaps pheophytin a). When ...
متن کاملSites of inhibition by disulfiram in thylakoid membranes.
Disulfiram (tetraethylthiuram disulfide), a metal chelator, inhibits photosynthetic electron transport in broken chloroplasts. A major site of inhibition is detected on the electron-acceptor side of photosystem II between Q(A), the first plastoquinone electron-acceptor, and the second plastoquinone electron-acceptor, Q(B). This site of inhibition is shown by a severalfold increase in the half-t...
