Sentence examples for photosystem II efficiency from inspiring English sources

However, sunflecks longer than 60 min led to a very strong decrease in A and in actual photosystem II efficiency (ΦPSII) in FSLE leaves, when compared to sunflecks shorter than 30 min.

The biological effect (algal growth, membrane integrity, oxidative stress, Chl fluorescence and photosystem II efficiency) of these NPs was investigated on green alga C. reinhardtii.

Fig. 6 Effect of a Au, b Pt, c Pd, d Ag and e CuO nanoparticles (1, 5, 10 and 20 mg/L) on photosystem II efficiency (QY %) after 1, 3, 5 and 24 h.

We then used a range of nanoscale concentrations (1 20 mg/L) related to expected or recorded environmental concentrations [39, 71 73] to assess the biological effect of the NPs on C. reinhardtii using endpoints such as algal growth, membrane integrity, Chl fluorescence photosystem II efficiency and oxidative stress.

We measured the ligand induced response using four different methods: quantitative measurements of GUS, visual changes, quantitative changes in photosystem II efficiency (Fv/Fm), and with quantitative RT-PCR.

This was correlated with measurements of photosystem II efficiency (Fv/Fm), which stayed unchanged for all treatments after 24 h of treatment (Additional file 4).

Photosynthetic pigment composition, content of α-tocopherol, CO2 assimilation, potential photosystem II (PSII) efficiency (evaluated by Fv/Fm ratios) and growth of T. panamensis and C. longifolium did not differ between seedlings developed under near-ambient and reduced solar UV-B.

Moreover, the biological effect of the NPs (concentration range 1.0 20.0 mg/L) on a unicellular green alga (Chlamydomonas reinhardtii) was investigated by assessing algal growth, membrane integrity, oxidative stress, chlorophyll (Chl) fluorescence and photosystem II photosynthetic efficiency.

Mechano-stimulation was reported to increase cold tolerance in beans, tomato, and maize through maintenance of higher Photosystem II (PSII) efficiency and accumulation of higher levels of soluble sugars [ 8].

Curves were measured in the morning to avoid confounding treatment and genotype effects with transient decreases in water potential, decreases in chloroplast inorganic phosphate concentration or decreases in maximum photosystem II (PSII) efficiency (Fv'/Fm').

Moreover, we found that NAA, similar to shading, directly interfered with leaf photosynthesis by repressing photosystem II (PSII) efficiency within 10 minutes of treatment, suggesting that NAA and shading induced some of the same early responses due to reduced photosynthesis, which concurred with changes in hormone signaling pathways and triggered fruit abscission.
