“…The synchronous source provides sampling pulses with duration of 1 µs and PPFD = 7.7 µmol m -2 s -1 . To improve signal-to-noise ratio, this PPFD is set to a significantly higher value than that common in PAM practice, yet it serves physiologically relevant information (Solti et al 2014). The significance of the PAM recording is the possibility of comparison to other commercial instruments, and the direct recording of the original fluorescence F0 and its minimal level (F0'1 and F0'2).…”

Molecular breeding, a powerful technique to increase crop yield, tries to predict yield by crop growth models with genotype specific, environment-independent yield components and environmental indices as inputs. A fluorescencetrait-based approach is presented to approximate some costly and time-consuming measurements of yield components. Temporal monitoring of chlorophyll a fluorescence resulted in fluorescence traits with high heritability (0.60-0.82) that could act as proxies for model inputs. Medium-sized Pearson's correlations were calculated between fluorescence traits, light-use efficiency (LUE), and fruit related parameters up to 0.53. Multi-trait quantitative trait locus (QTL) analyses identified genomic regions of pepper (Capsicum annuum L.) involved in the phenotypic variation of the fluorescence traits. Fluorescence QTLs found on linkage groups P6, P7, and P11 corresponded to QTLs for number of fruits, partitioning into fruits, and LUE. Fluorescence parameters within 1 min of the fluorescence response curve can thus be useful to approximate yield component traits.

“…PPFD of 3500 lmol m -2 s -1 was applied every 100 s as long as the F m values remained unchanged, after which the light-adapted quasi steady-state fluorescence (F s ) and maximum fluorescence yield in the light-adapted state (F m 0 ) were determined. To assess the excitation energy allocation, the quenching parameter values were calculated according to Hendrickson et al (2005) used as in Solti et al (2014):…”

“…These compounds provide protection against cell damage and reactive oxygen species, and are considered to be general responses against biotic and abiotic stressors (Hideg et al 2002;Meyer et al 2003;Hura et al 2007;Solti et al 2014). As one of the main products of the phenylpropanoid pathway, chlorogenic acid is also involved in photochemical energy dissipation pathways in tobacco (Piñeda et al 2008).…”

The beneficial and protective effects of Smethylmethionine (SMM) were investigated in Maize dwarf mosaic virus (MDMV) infected maize (Zea mays L.). Response reactions and alterations in the physiological state of the plants were monitored by following changes in the values of chlorophyll a fluorescence and chlorophyll content, and differences in the expression patterns of the stress-related genes S-adenosylmethionine synthase (SAMS) and the 14-3-3-like protein gene G-box factor 14-6 (GF14-6). Infection was validated using the ELISA technique. A pronounced decrease in the red to far-red chlorophyll a fluorescence ratio, indicative of chlorophyll content, was observed in infected plants, which was tempered by SMM pretreatment. A noticeable decrease in the photochemical quenching of photosystem II and the thermal dissipation of the antennae was observed, together with a notable increase in other non-photochemical energy dissipation parameters in response to MDMV infection. SMM treatment enhanced blue fluorescence in both uninfected and MDMV-infected plants (probably due to the production of protective phenolic compounds), while infection characteristically increased green fluorescence emission. SMM treatment was found to elevate the rate of gene expressions of SAMS and GF14-6. The results suggest that SMM pretreatment enhances the stress response reactions that protect maize plants against MDMV infection.
