- It also decreased the photochemical efficiency (Δ F / Fm ′) of PS II under actinic light, electron transport rate ( ETR ) and ATP content per unit leaf area but increased the intercellular CO 2 concentration and non photochemical quenching of chlorophyll fluorescence ( NPQ ).
- Non photochemical Quenching of Chlorophyll Fluorescence in Soybean and Sweet Viburnum Leaves
- Furthermore, ALA treatment led to both the increase of photochemical fluorescence quenching and non photochemical fluorescence quenching, where the former increased the leaf photochemistry rate, and the latter was associated with the increased energy dissipation via thermal in the antenna and the thermal dissipation rate.
- In order to observe the responses of non photochemical chlorophyll fluorescence quenching ( qN ) as well as the change courses and components of qN to drought and shade stresses, these parameters were measured in different treatments.
