Estimating chlorophyll content and photochemical yield of photosystem II (ΦPSII) using solar-induced chlorophyll fluorescence measurements at different growing stages of attached leaves.

Bottom Line: The steady-state solar-induced Chl fluorescence yield ratio correlated very well with the artificial-light-induced one (R(2) = 0.84).A new methodology is then presented to estimate photochemical yield of photosystem II (ΦPSII) from the SIF measurements, which was verified against the standard Chl fluorescence measurement method (pulse-amplitude modulated method).The high coefficient of determination (R(2) = 0.74) between the ΦPSII of the two methods shows that photosynthesis process parameters can be successfully estimated using the presented methodology.

Figure 6: Relationship between artificial-light-induced Chl fluorescence yield ratio (ΦFa686.4/ΦFa760.5) and solar-induced yield ratio (ΦFs686.7/ΦFs760.4) at different growing stages of paprika leaves.

Mentions: Figure 6 shows a linear correlation between artificial-light-induced Chl fluorescence yield ratio (ΦFa686.4/ΦFa760.5) and the solar-induced one (ΦFs686.7/ΦFs760.4) obtained at the optimal W (W = 0.4nm). The regression line was very close to the y = x line.
