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

Tubuxin B, Rahimzadeh-Bajgiran P, Ginnan Y, Hosoi F, Omasa K - J. Exp. Bot. (2015)

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 3: Relationships between leaf Chl content and steady-state artificial-light-induced Chl fluorescence yields. (A) ΦFa686.4. (B) ΦFa760.5.

Mentions: Figure 3 shows relationships between leaf Chl content and steady-state Chl fluorescence yields of ΦFa686.4 and ΦFa760.5 under artificial light. The Chl fluorescence yields of ΦFa686.4 decreased with an increase in Chl content (Fig. 3A), whereas those of ΦFa760.5 increased (Fig. 3B), although the yields greatly varied at low Chl content below about 200mg m−2. At higher Chl content with more than about 400mg m−2, the changes in ΦFa686.4 and ΦFa760.5 become small.
