The aim of this educative review is, by revisiting the JIP-test as introduced and further elaborated and extended by Professor Reto J. Strasser and his research group, to clarify concepts, assumptions, and approximations on which it is based, as well

In this study, water solutions with different concentrations of abscisic acid (ABA) (10, 20, and 40 μmol L-1) were sprayed on leaves of drought-stressed tobacco seedlings. The results showed that under drought stress, both water content and photosyn

The study was carried out to examine the photosynthetic efficiency of Scot pine populations, originated from various European countries and Anatolia in Turkey, exposed to UV-B radiation. Seeds were germinated and grown in the nursery; three-year-old

The performance of PSII photochemistry in five Central European provenances of silver fir differing in the altitude of origin (250-1,300 m a.s.l.) were studied using the chlorophyll a fluorescence parameters derived from the JIP-test. Measurements we

Generally, excessive excitation absorbed by the pigments is considered the cause of PSII photodamage. Previous studies of action spectra of PSII photodamage concluded that shorter wavelengths induce more damage, supporting the hypothesis of the exist

The effect of salinity on primary photochemical reactions (using JIP-test) in six sweet sorghum genotypes was tested. An increase in salt concentrations induced significantly the accumulation of proline and caused a decline in leaf osmotic potential.

Plants adapt to the environmental stresses by using the signalling molecules, such as H2O2 and nitric oxide (NO). We have assessed the NO-induced changes by using sodium nitroprusside (SNP, a NO donor) in photosynthetic components in protoplasts of p

In the current research, we used chlorophyll fluorescence measurements and photosynthetic pigment content to evaluate onset and rate of the flag leaf senescence every 7 d beginning at the flowering stage (0 d after flowering, DAF) until late senescen
